5 major benefits of 3D printing in education

There are a few considerations before you start:

What are the objectives of "getting" a 3D printer?

Who will be the main users of the 3D printer? - Students, Teachers or technical staff?

Budget

Location and position of the 3D Printer

A few considerations when choosing a 3D printer/vendor:

Ease of use of 3D printer and associated slicing software (more information on this below) - Check on levelling procedures and material loading/unloading procedures

Quality of prints - Are you able to get good prints with very little intervention or is the printer more technical and you need to be available to mess with settings?

Warranty and after-sales service - This is incredibly important, things will go wrong and you don't want to be left in a bad situation. Most warranties will not cover nozzle clogs, find out how much these will cost to remedy

Is the 3D printer able to use third-party materials? What are the materials used and tested on the 3D printer being considered?

What is 3D Printing?

An in-depth but not so technical explanation of 3D printing and the different technologies

The 3D Printing Process

The 3D Printing Process consists of 4 main steps.

Design -> Slicing -> 3D Printing -> Finishing

1. Design

You can either choose to design the products on your own or you could download models from the internet. Sites such as Thingiverse and Myminifactory provide users access to many files from various different interests, there is something for everyone. A good introduction would be to get students to explore and download models of interest to them from these sites.

2. Slicing

You would have to convert these 3D Designs (or CAD files, which should be in either STL or OBJ formats) into codes that your 3D printer will be able to understand. Slicing Softwares are particular to each 3D printer. Flashforge models available on our store use Flashprint. At this point, you would have to decide on the orientation of the print to minimise print time and supports (supports are like scaffolding, because 3D Printing is a layer on layer additive technology, you can't build layer 2 with layer 1 for support. Supports act as a bottom layer for top layers to be built on).

3. 3D Printing

Level your build plate -> Load Filaments -> Send the sliced files (from step 2 above). Make sure to watch the first (or first few layers of print) to ensure that the layers are sticking to the build plate and that they are sticking to each other. This is important. After which, you can leave the 3D printer to churn on it's own. Make sure to check back once in a while, you never know what problems can arise.

4. Finishing

Most of the time you would be doing basic clean-up like breaking off supports and cutting off any stray bits of filaments. You could also sand, spray paint or manually paint your 3D prints. Depending on materials you are working with, you would have to use different paints. But typically, acrylic spray paints work well.

Design Software for schools

There are a few design softwares that have been made specially for educational institutions.

1. Autodesk Fusion 360 - Free for educators and educational institutions. Plenty of free tutorials linked directly from the software and also on Youtube and a great community of creators online who are always happy to help. Most commonly used nowadays by design and engineering firms.

2. Makers Empire - Claimed to be one of the world's easiest-to-use 3D Design Software, it's specifically designed and suited for schools and educational institutions. They even have a monthly design competition that users can take part in to test their skills. One of the best choice for 3D Printing in Schools.

3. TinkerCAD - One of the early pioneers of 3D Design Software for Kids, it is also an offering from Autodesk. Simple easy-to-use interface and functions make this software great. It's also powerful- there have been many stories of designers using TinkerCAD to create professional/consumer products for sale.

Activities with students

As mentioned before, you can get students to explore and download their own models from sites such as Thingiverse and Myminifactory, or you can get them to design their own objects. An alternative is to get them to use generative design systems such as the Cell Cycle App from Nervous System. This helps students understand certain basic concepts with design and manipulation of models. It might even give them ideas about creating their own custom designs.

Explore more generative design apps.

There are plenty of other actives and subjects that can be covered with 3D printing, we'll add more as we go along.

Troubleshooting

3DVerkstan have most comprehensive and well-written guide on the internet to printing problems with an Ultimaker printer, but many of the troubleshooting tips apply to many other 3D printers http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide There is also an associated “Getting Better Prints” guide on the same site http://support.3dverkstan.se/article/30-getting-better-prints Simplify3D also has a great resource on troubleshooting print quality - https://www.simplify3d.com/support/print-quality-troubleshooting/

Epoxy coating for a smooth finish:

Small items - within a 5x5x5cm bounding box - $10

Medium items - within a 10x10x10 bounding box - $20

Large items - larger than 10x10x10 bounding box - $30

PLA

Polylactic acid is a versatile and low-cost 3D printing material. Due to its accuracy and ease of use, it is the widely accepted standard for 3D printing materials.

3D prints made with PLA are rigid and strong. PLA has been used to fabricate everything from decorative items to functional products for use in form and fit testing applications.

PLA is a bio-degradable polymer created from processing plant parts. It is considered more “Earth- friendly” than any other 3D Printing material.

PLA is available in about 60 different colors.

PET (PolyEthylene Terephthalate)

PET is one of the most commonly used plastics worldwide. It is a strong and tough material that can withstand higher temperatures than other 3D printing materials.

PET is available in a range of colors with varying translucency. Its glossiness and translucency can be manipulated to produce 3D prints with finish similar to glass.

PET is ideal for end-use and functional products including moving parts. It is one of the safest filaments to use for children’s toys and any part that would need to be in contact with food or drink (ensure your extruder is food-safe too).

Dissolvable Filaments (HIPS and PVA)

HIPS and PVA are two different types of dissolvable filaments commonly used to 3D print support structures. Using dissolvable filaments makes removal of support structures easy and less time consuming. Using dissolvable filaments also helps to create intricate shapes which would otherwise be impossible.

HIPS is best used with ABS while PVA is best used with PLA and other materials. HIPS dissolved in Limonene while PVA dissolves in cold water.

Wood-infused filaments

Wood-infused PLA Materials give a warm and tactile finish similar to that of wood. It is also one of the easiest 3D printing material to work with - no need for any specialised extruders and heated build platforms.

The final product can be sanded and stained just like normal wood. If your final product is to be made with wood, use these filaments to test the final feel of your products.

Carbon-Fibre infused filaments

Carbon-Fibre infused PLA filaments are comprised of approximately 20% chopped Carbon Fibre filaments infused with either Polylactic Acid (PLA) or PolyEthylene Terephthalate (PET) filaments. Carbon-Fibre Filaments are more rigid than conventional PLA and PET. Yet, it is easy to print with standard PLA settings. The matte-black of Carbon-Fibre infused PLA filaments gives a nice finish that helps to mask layer lines.

Carbon-Fibre infused PLA filaments are ideal for end-use products such as drones and RC cars.

Metal-infused filaments

Metal-infused PLA filaments are comprised of approximately 20% metal shavings infused with PLA filaments. Metal-infused PLA filaments cool and solidify very quickly which allows for faster printing speeds. This also allows the printing of designs that may not be possible with other filaments.

Models printed with metal-infused PLA filaments can be sanded to obtain a finish similar to metal.

Thermoplastic Elastomer (TPE) Flexible filaments

TPE is an exciting filament that allows you to print soft and flexible products with a finish similar to that of rubber. TPE is also resistant to UV and certain common chemicals.

TPE is ideal for projects that require flexibility and elasticity. TPE filaments are good for many wearable electronics applications. In addition, it can also be used to create shoes, handlebar grips and even tires for RC cars. With the right settings, TPE prints are watertight which is great for floatation devices.

Today, 3D printing is here to stay as millions of people are now taken advantage of its ability to create art by either becoming hobbyist or professionals in the continuously advancing field of 3D printing.

Now for those who fall into the ‘hobbyist category’, this should be viewed as a slightly more advanced guide on some of the tools you would require in taking your art to the next level. This guide will contain a short review of the listed items, their uses and approximate cost to help you make more informed purchasing decisions.

1. Refine with a Rotary Tool

There are certain sanding, cutting and smoothing tasks you may have undertaken only to discover that your traditional tools—pliers, knife, screw drivers etc.—couldn’t execute these tasks accurately or without slightly deforming the printed model.  This calls for a more powerful tool which can provide the leverage and strength needed to accurately handle the stated activities. The Dremel 4000 is a high performance rotary tool ergonomically designed to simplify handling regardless of your cut angle.

More importantly, the Dremel 4000 comes with multiple tool head accessories which are suited to cutting, smoothing and burring tasks. Its attachments are powered by a variable speed motor as well as an electronic feedback to track its speed.

2. Keep Watch with a Wireless Camera

Every 3D printing enthusiasts has his or her time keeping method when printing time-consuming projects. Some set timers on their printers when printing components, while others have ears which are fine-tuned to understanding every sound their printer emits but there is an easier way. Installing a camera to cover your work space while receiving periodic updates on your mobile device is a much better method of keeping track of projects. Blink is a wireless camera with approximately a years’ battery life. After installation, you can watch live feeds on your mobile device and also receive motion alerts if you are a parent who suffers from the ‘snooping kid’s syndrome’.

3. Light it up with a Flashlight

Although more modern domestic 3D printers are being built with integrated lighting to aid a user’s sight, the average 3D printer in today’s market does not come with this feature. Therefore, the responsibility of strategically lighting up your workspace falls on you. But if like most of us, you still experience some blind spots when printing or finishing a model, you should consider purchasing a LED flashlight to increase all-round visibility.

4. Track Temperature with a Laser Thermometer

As a true 3D printing professional, it is important to note that you are now playing in the big leagues and as such, it is important to keep track of every aspect of the 3D printing process that may affect the quality of your work. Some of these aspects to track are; inadequate heating when using a heated print bed, the temperature of the 3D printer’s nozzle and the heat distribution to the outer edges of the heat bed. The Kkmoon contactless laser thermometer is the perfect tool for keeping track of your workspace’s temperature and at $24 this precise thermometer with an intuitive display screen is a steal.

5. Build Models on a Polycarbonate Board

Carrying out 3D printing projects by printing on the traditional masking tape should be considered the ‘old way of doing things’ for they get in the way when removing completed builds. On the other hand, polycarbonate boards are a thin yet durable alternative to masking tapes and they provide an optimal surface for 3d printed models to adhere to. Another added advantage it has over its contemporary is its re-usable nature which eliminates the need for constant replacements and waste.

6. Dry Filaments with Desiccant (or a dry-cabinet, if you are really serious)

As a 3D enthusiast, you must have definitely realised that water is an enemy to your equipment and workstation which means it must be kept out by every means necessary. Most people I know make use of sealed plastic bags and containers to keep out the moisture from their filament stash. While this isn’t completely fail-proof putting desiccant bags into the container or bag may prolong the lifespan of your materials.

Image source: Amazon

There is now an alternative that is better than Desiccant and much cheaper than a Dry-Cabinet. Meet PrintDry. PrintDry is a filament feeder that actively dries the filaments placed within, much like a dry-cabinet or oven.

7. Size Difficult Angles with the Sliding Bevel

When working on small designs with intricate angular edges, the need to accurately measure small angles become extremely important in order to retain your model’s exact dimensions.  In such circumstances, your digital angle finder cannot read these minute angles. Therefore, purchasing a sliding bevel as an added accessory to compliment efforts of a digital angle finder is the way to go. To do this, simply fit the bevel onto the angle and then use the digital angle finder to read it. The sliding bevel can also be used as a check and balancing instrument for maintaining angle consistency along the length of an object.

8. Capturing Curves with the Contour Gauge

The contour gauge is a tool designed to accurately capture the profiles or outline of surfaces spotting multiple curves. For a better understanding, simply imagine trying to build a holder to stick to your car’s dashboard and the difficulties you encounter trying to accurately get the dimensions of its curves. Simply slap the gauge on the dashboard and then trace its shape on paper. You can then import this shape into your digital model or CAD application as either an SVG or DXF file, before proceeding to the 3D printing process.

9. Troubleshoot with a Mechanic’s Stethoscope

This tool is for the serious hobbyist and DIY enthusiast who are willing to dig deep when solving problems associated with his or her 3D printer. The mechanic’s stethoscope is equipped to help with the locating of errant noises emanating from your printer. Simply press the probe firmly to faulty areas to listen to the sounds coming from them.

10. Computer Aided Design Software

The next professional stage for every competent  artist looking to gain some renown is creating original art works that showcase one’s creativity and the world of 3D printing is no different. Mastering the interface of a computer aided design application (CAD), gives you the freedom to be creative while viewing the results of your art in real-time. With CAD, you can design virtually anything you choose and import the finished product for printing on your 3D printer. This gives you the unlimited creative control you desire that cannot be experienced using a 3D scanner or purchasing stock 3D models from the internet.

So there you have it, our top 10 3D printing tools listed for those looking to expand their abilities to the next level. Note that you can easily purchase some of these items online or at your local store depending on your location. In conclusion, it is important to note that practice makes perfect, so keep surprising everyone including yourself, by building innovative items which could add that little piece of magic to our world.

As popularity increases, you might consider getting your own personal device. You may wistfully think about how nice it could be and shelve the idea with so many other thoughts in your head. Before you do, consider the real-life practicality that these machines can offer.

Even though quality printers feel very expensive today, there are a number of good reasons to invest sooner than later. Even if you find yourself waiting in the short-term, you can expect prices to fall as rapidly as most new technologies, and as they continue to come down in price, homeowner level models offer more and more potential. This is only the very beginning of what a 3D printer could do for you.

Print Your Household Needs

3D printers were originally designed to create extremely precise, specialized tools for scientific and engineering research projects. As researchers wanted the freedom to try some designs at home, they pushed the market into more domestic reaches. What does this mean for the home-end user? Well, the sophisticated resources of 3D printing can give you access to tools that used to cost hundreds or thousands of dollars apiece. Now, with the right design, you can make such things for a few dollars worth of materials.

With every tool under the sun at your fingertips, worlds of possibility open. Need a special pipet to decorate a cake? Print it. Can’t reach a bolt to fix your car? Print a ratchet joint. The custom size washer broke in your plumbing? You can print them all. Any job around the house that might need a specialized tool is now within your domain when you master your personal printer. The best part is that you don’t have to make the designs yourself. Places like YouMagine and Thingiverse offer downloadable models that give you professional level precision for every situation.

Fix Anything

As useful as the infinite options for tools are, many repairs require a special part to fix. Obscure plastic latches seem to be the linchpin for all modern construction, and ordering the right replacement part is a dubious prospect. A 3D printer solves this as easily as you might imagine, making an exact part to replace exactly what is wrong. Whether you are fixing furniture, appliances or toys, the sky's the limit.

If you worry about being able to successfully model the right part when you need it, fear not. Like with everything else on the list, there are communities dedicated to providing parts for every need imaginable. Groups like Kazzata have dedicated their efforts to helping manufacturers create and maintain 3D printing designs for every spare part. They uphold their obligations to supply replacements while minimizing production and storage costs. Those savings are returned to end users and everyone wins. Now you can skip waiting for shipments, arguing with customer service or long drives to acquire special pieces.

Prepare for the Future

This is definitely a technology where you want to be ahead of the curve. Investors are poised to put 3D printers in every home, and it’s only a matter of time before manufacturers are able to make that a reality. Researchers have successfully printed: customized bionic limbs, replacement human organs, entire meals, medication, musical instruments, clothing, bicycles and houses. So, while a 3D printer at home might feel like a large investment today, you can see the unlimited potential that these tools hold for tomorrow.

“Why not wait?” You might wonder. 3D printers are not as simple and straightforward as the paper eating monsters that sit in every office and many homes. They require some learning and familiarity to operate with success. While innovations promise to reduce some of the user burden, you will ultimately need to learn how to use the technology if you want to have access to all of these wonderful promises. Much like with smart phones, adopting early will put you ahead of the curve and prepare you to make the most of the endless potential that is inevitably headed your way.

Have Fun

All of these uses and potentials can be dizzying, but there is one reason that stands above the rest to invest in a 3D printer: fun. All of the good intentions for designing and fixing things are great, but unless you latch onto a personal enjoyment, the printer is likely to collect dust with a number of other things in your home. This tool is a resource to help you unlock every corner of your creative mind, so go into it expecting a good time. Make things that appeal to you on a personal level and use that drive to gain familiarity and mastery of your printer and software. If you do, the other uses will always be at your beck and call.

But would it surprise you to know that 3D printing technology could also be making its way into your favourite restaurant reproducing the swirls on your favourite dessert. What’s next outer space? Would it surprise you to hear that NASA is developing the technology right now to produce food through the use of 3D technology? What if you were told that a 3D printer could extend your life?

3D-Printed Hearts Help Surgeons Save Babies’ Lives

After a table saw accent Richard Van lost two fingers, and mangled two others. He was determined to find a way to return to work, but after some research realized that prosthetics were too expensive. After some further research and collaboration with Ivan Owen, Van developed a working mechanical finger. He continues to make hands at no cost to children in his region. He calls these hands Robohands.

Make Your Own Robot

3D printing is giving animals needing prosthetics a second chance at life. While traditional prosthetics were an option, 3D printing allows these prosthetics to be made low-cost and on-demand - and this is important as the prosthetics needs to be revised several times to keep up with the animal’s growth.

Developed by Tatsuya Honda, this 3D hairclip, called the Ontenna, transfers the vibrations through the hair to enable the wearer to differentiate one sound from another.

Print Your Dinner (Edibly!)

Image Source: Inhabitat

Yes, 3D printed foods are a thing - just think, hot food with the touch of a button! Choose your cartridge, add some water and voila - dinner is served. The catch is we are still years away from perfecting this type of 3D printing. With the projected increase in world population to reach 9.7 billion by 2050 3D food printers will help to reduce food waste and feed the growing population. Furthermore, printing foods, as they did in Star Trek, will allow people to venture further into space.

Personalize Your Exercise Gear

Shoes, swimming gears, and even racing cars can be 3D printed. While 3D printed shoes may be more costly than those in stores, athletes report that 3D printed shoes allow more agile movements because they are lightweight. Currently, these shoes are not available to the consumers, but it will be a thing in the near future.

Make Your Own Tools

If you’ve ever misplaced that wrench, or didn’t have the right size wrench, don’t go out and buy one! Make one with your 3-D printer!

Micro Batteries for Miniature Devices

Image Source: Top Info Post

Harvard researchers have created 3D printed lithium-ion batteries that can be used in portable and remote devices useful for industries like communications, defense, and medicine. Applications include the use for miniaturized devices, including medical implants, flying insect-like robots, and tiny cameras and microphones that fit on a pair of glasses.

The Future of 3D Printing

It would appear that 3D printing will change the world. 3D printers are helping people heal bones, pick up a pen for the first time, a dog run, and an eagle eat. Does this mean our future’s looking brighter? Well, if it is then you need a pair of sunglasses - and the 3D printer can always print you a pair.

No crowds - my favourite reason to do any sort of online shopping

A 3D printer should in no way be an impulse purchase, it’s a tool that requires plenty of attention and care. So read on and get in touch with us at [email protected] should you have any questions.  

1. Reliability

Can you do a long print without worrying about the 3D printer stopping halfway? What must you take note of? Is the extruder mechanism a workhorse?

2. Ease of use

From importing your design file to actually pressing print on the 3D printer, how do I do it? Is it an intuitive system? Can I explore and make changes to the settings easily?

3. Build platform

What sort of preparation must I do to the build platform before 3D printing? How do I ensure that the materials being extruded stick to the build platform and when the print is done, how do i remove it?

4. Slicing Software

Does it come with it’s own slicing software? What is the update schedule like? Can the software generate supports automatically? (Supports are sort of like scaffolds, they are necessary to 3D print more complicated designs.)

5. Warranty

How long is the manufacturer’s warranty? What happens after that? What does the warranty cover and what doesn’t it cover?

6. Materials capability

So does your 3D Printer require 1.75mm filaments or 3mm filaments?

Does your 3D printer need any special modifications to take other specialty filaments such as Ninjaflex or any other flexible 3D printing materials?

Look for what has been tried and tested, see some test prints. This may not seem so important now, but when you get bored of the norm, this becomes necessary.

7. Test prints

Can I see some test prints from the 3D printer? Can I see a whole print process till the start of printing? What are the retraction settings and capabilities of this 3D printer. How have they been tested? One of my favourite test prints for clients is the Voronoi Torso. With this print, you get to see the movements, speed of printing and retraction - all at the same time. Of course, you don’t have to complete the print, just go about 10-20 minutes in.
