Selective Laser Sintering (SLS)

The strongest and highest temperature thermoplastics with quality finish 

Design Guidelines

Please note that these are are GUIDELINES, not hard and fast rules. Follow these and you should be in pretty good shape, but we'll let you know if we see any problems.

Parameter Inches Milimeters
Maximum part size 27.6 x 15 x 22.9* 700 x 380 x 580*
Expected Tolerance +/- 0.3%** +/- 0.3%**
Minimum Supported Wall Thickness 0.030 0.75
Minimum Unsupported Wall Thickness 0.030 0.75
Minimum Supported Bosses 0.030 0.75
Minimum Unsupported Bosses 0.040 1.00
Minimum Embossed Detail (Height and Width) 0.020 0.50
Minimum Engraved Detail (Height and Width) 0.020 0.50
Clearance 0.020 0.50

*Build volume is up to 27.6 x 15 x 22.9 inches. Larger models can be made in sections and pieced together after printing.

**Large SLS parts can be prone to warp, which explains the scaling tolerance. Minimum tolerances are +/- 0.010.
