Design Guidelines: Selective Laser Sintering
Our basic guidelines for selective laser sintering include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
We offer a number of secondary services to further enhance your 3D-printed project design or finish. These services are available when ordering a part manufactured by Protolabs.
|PA 12 White||676mm x 367mm x 564mm|
|PA 11 Black*||269mm x 320mm x 406mm|
|PA 12 40% Glass Filled||269mm x 320mm x 406mm|
|PP Natural*||269mm x 320mm x 406mm|
|PA 12 Carbon Filled||490mm x 490mm x 740mm|
|TPU-88A Black||330mm x 280mm x 440mm|
*PA 11 Black and PP Natural - Suggested maximum dimensions: 200mm x 200mm x 200mm (higher dimensions may increase warping and dimensional inaccuracy risk)

|Minimum Feature Size||0.75mm* / 1.00mm**|
*PA 12 White, PA 11 Black
** PA 12 40% Glass Filled, PP Natural, PA 12 Carbon Filled, TPU-88A
Typically, expected tolerances on well-designed parts are +/-0.2mm, plus +0.002mm/mm
*For TPU-88A Black, tolerance of ± 0.3mm plus ± 0.002mm/mm can be expected (for parts bigger than 100 mm in this material, tolerance will be ± 0.3% of nominal dimension)
|STANDARD||Bead blast to remove all powder, which leaves a consistent overall texture.|
||Secondary options include a primer or dye colour that can be applied as well as taps and inserts.|
Our SLS equipment includes sPro140 machines, which have a large sintering build volume, and feature fully digital high-speed scanning systems, unparalleled process consistency, and closed systems for powder blending and delivery for reliable part quality. We also use SPro 60 machines, which allow for multiple materials and high throughput.
