Unlock the potential of micro-scale 3D printing with smarter CAD design.


When you’re designing at the micron level, the rules change—tiny walls collapse, channels clog, and tolerances that work at the macro scale fail at the micro scale. This guide shows engineers how to adapt their CAD models to take full advantage of Boston Micro Fabrication’s (BMF) 2µm resolution, ±10µm tolerance printers.

What You’ll Learn

  • Resolution vs. Tolerance – How to set realistic tolerances and avoid over-specifying.

  • Wall Thickness & Structural Integrity – Minimum guidelines, reinforcement tips, and orientation strategies to prevent collapse.

  • Supports & Overhangs – How to design parts that minimize support use and simplify removal.

  • Microfluidic & Channel Design – Best practices for channel diameters, aspect ratios, resin drainage, and flow performance.

  • Material Selection & CAD Settings – Matching resin properties to applications and exporting high-resolution CAD files for success.
