A dinner service for six, nested in one SLS build

Drag to orbit, pinch or scroll to zoom. Slide the build order to watch the bed fill from the bottom; turn on the cutaway to see the bowls inside bowls and the pieces under the rims.

Nested against boxed

The same 30 pieces, the same packer, the same 3 mm gap and the same search. The only difference is whether a piece's hollow is usable space.

How the pieces fit together

• Bowls in bowls. The 18 bowls sit inside one another, smaller in larger, each one clear of the bowl around it by 3 mm of powder.
• Plates in plates. Dinner and side plates stack into each other's wells, upright and upside down, foot ring into well.
• Under the rims. Pieces tuck under the overhanging rims and flanges of the pieces above them. In a powder bed nothing needs a path in or out, only a gap.
• Proved twice. Every pair of pieces is checked on the real triangles by cad_nest's own proof and again by a second, separately written checker. Both report 0 collisions and a closest gap of 3.00 mm.

Each piece is a revolved solid from the NativeCAD kernel: well, rim and foot ring. The build is SLS, PA12 at 3 mm between parts and 5 mm off the chamber walls.

X1 Carbon plate: 15 Labs Planetary pendants

15 working Labs Planetary pendants, each a print-in-place gearbox with six planets, nested on one Bambu X1 Carbon plate at 54% utilisation. No two pendants come closer than 5.2 mm, proved on the real triangles. Every pendant prints back face down, the orientation the X1C rule pack ranks first, and the plate takes about 7 h 30 min at 0.12 mm layers in two colours. That figure is an estimate from the part volumes, not a slice.

Drag inside the scene to orbit, scroll to zoom. Each pendant is 52.8 × 68.1 × 14 mm with its bail; cad_nest turned them in 90° steps so each bail tucks in between its neighbours, 5 mm apart and clear of the purge corner.
