Before designing a 3D CAD file for 3D printing, it's important to consider the technology and material you'll be printing with. Each process‚ FDM, SLA, MJF, or VCJ‚ has its own design rules around wall thickness, overhangs, support needs, tolerances, and orientation.
Here are key things to keep in mind:
Wall thickness: Don't go too thin‚ each material has a minimum requirement (e.g., 0.8mm+ for most plastics).
Tolerance planning: If your part involves mating features or assemblies, build in clearance based on the material's accuracy.
Overhangs and supports: Avoid extreme angles or unsupported geometry, especially for FDM and SLA.
Orientation: Design knowing how the part will be printed‚ flat surfaces, fine details, and structural load all benefit from correct orientation.
Export correctly: Always export a watertight STL or STEP file, at actual size and in millimeters.
