An SLS lattice is often the first idea for a lightweight part. On 3D Printing Stack Exchange, a designer planned a 30 × 30 × 10 cm tricopter frame made from a tetrahedral honeycomb, with struts about 1 mm thick and 15 mm long, printed in nylon on SLS. They asked...

SLS minimum wall thickness questions usually come after a part has already failed. On 3D Printing Stack Exchange, a customer had a Nylon 12 part printed by an online SLS service. It “looked great” but didn’t work as expected, and they wanted to try...

SLS internal channels look great in CAD, but every channel prints full of unfused powder. On 3D Printing Stack Exchange, a designer planned 1.5 to 2 mm wire raceways inside a polypropylene SLS part and asked whether they were worth the trouble, and what tools could...

Customers ask bureaus to paint SLS parts when dye can’t hit the color they need. On the Formlabs forum, a Fuse 1 user wanted Nylon 12 parts painted opaque white, “with no see through,” to match powder-coated metal plates in RAL 9003 Signal White. Can...

SLS bead blasting should leave parts clean, but sometimes it leaves something behind. On the Formlabs forum, an operator two weeks into using a Fuse Blast found a “tacky” white residue on parts coming out of the tumbler. It felt like a woodworker’s...

SLS scaling calibration is how you get parts to come out at their nominal size. A Fuse 1+ user on the Formlabs forum reported that every component came out 0.3 to 0.5 mm short in Z. X/Y scaling kept flat dimensions in check, but they wanted the same kind of fix for Z....
