Powder Bed Fusion 3D Printed Parts Design Guideline

These design guidelines for powder bed fusion help optimize part performance by addressing critical aspects such as feature size, wall thickness, supports, orientation, and more. Following these recommendations improves precision, structural integrity, and overall print quality.

Design Aspect	Guideline	Reasoning
Minimum Feature Size	Typically 0.5 mm or greater	Ensures that small features are robust enough to be built and remain intact.
Wall Thickness	Minimum of 0.8 mm; recommended 1 mm or greater	Thinner walls may not fully fuse or could be too fragile to handle post-processing.
Supports	Often required for overhangs greater than 45° and large spans	Supports stabilize the structure during printing and prevent warping.
Orientation	Optimize to reduce the need for supports and minimize exposure to the heat source	Reduces post-processing and potential distortions due to heat stress.
Escape Holes	Include for enclosed and hollow parts to allow powder removal	Ensures that unsintered powder can be removed from complex internal cavities.
Clearance	Minimum of 0.5 mm for parts intended to fit together	Compensates for powder fusion inconsistencies and ensures proper fit post-processing.
Layer Thickness	Typically ranges from 20 to 100 microns	Finer layers yield better surface finish and detail but increase build time.
Post-Processing	Necessary for surface finishing and to improve mechanical properties	Powder bed fusion often leaves a rough surface that requires smoothing.
Aspect Ratio	Keep aspect ratio low for unsupported features	High aspect ratios may lead to failure during build due to insufficient support.
Infill	Solid infill isn't always necessary; strategic use can save material and time	Using less than solid infill can reduce weight and material usage without compromising strength.
Surface Quality	Bottom surfaces in contact with powder may differ from top surfaces	Powder-contact surfaces might be rougher and require post-processing.
Thermal Distortion	Consider the effects of localized heating and cooling	Designs should minimize large cross-sectional areas to reduce thermal distortion.
Tolerance	Expect ±0.1 to ±0.3 mm depending on material and machine	Accounts for thermal expansion and variability in powder particle size.
