When you shrink a successful macro design down to micro-scale, things break: walls collapse, channels clog, and “good enough” tolerances stop being good enough. We put together a concise guide to help you design CAD models that actually print and perform at the micron level.
Inside, you’ll get:
- Resolution vs. tolerance—decoded: set tight specs only where they matter most.
- Wall thickness & structural integrity: minimums that survive printing and post-processing, plus ribs/fillets that add strength.
- Overhangs & supports: orientation tricks to minimize supports and simplify removal.
- Microfluidic channels: go-to diameters, aspect ratios, and drainage strategies for clean, functional flow.
- Materials & CAD export settings: match resin to application and avoid mesh/export pitfalls that derail accuracy.
Why this matters: BMF printers deliver feature resolution down to 2µm and tolerances to ±10µm—but unlocking that precision starts in CAD. Design smarter and you’ll cut failed prints, reduce iteration cycles, and reach validation sooner.
