When it comes to architectural model making, the technology you choose directly impacts how your vision is perceived.
Should you go with SLA or FDM?
In the latest blog by Fixie 3D, the key differences between these two popular 3D printing technologies are broken down specifically for architectural applications — not just general manufacturing.
🔍 SLA (Stereolithography) • Exceptional surface smoothness • High detail accuracy • Perfect for intricate façades, window frames, and presentation-ready components • Ideal for client-facing display models
However, SLA typically involves higher material costs and longer production times.
🔧 FDM (Fused Deposition Modeling) • Cost-effective and scalable • Faster for larger structural components • Suitable for massing studies and early-stage prototypes
But when it comes to ultra-fine detailing, FDM may require post-processing to achieve presentation quality.
For architecture firms, developers, and model studios, the decision isn’t about which technology is “better” — it’s about which one aligns with your project goals, timeline, and presentation standards.
In many cases, a hybrid strategy delivers the best results: SLA for fine-detail elements and complementary fabrication methods for larger structures.
If you’re planning your next architectural model, this guide provides practical insight to help you choose wisely.
