Thick pellet layers sag past 45° and pellet supports fuse to the part. Orient it, chamfer under ledges, or use Dual Filament (IDEX) for soluble supports.

On a large part the inside is where the hours go. Shell every solid; 10 to 25% infill gives most of the strength, above 50% is paying for nothing.

1 mm: up to 2.5 mm line, 0.75 mm layer. 3 mm: 8 mm line, 2 mm layer. 5 mm: 14 mm line, 3 mm layer. Walls in whole beads.

Round every corner (5 to 10 mm over 500 mm), break up flat floors, keep walls within a factor of 2, let the part cool on the bed.

Scale = 100 ÷ (100 − shrink %). A 1,000 mm part at 0.8% shrinks 8 mm. Calibrate at full size, X and Y apart from Z.

Half a bead in XY and half a layer in Z on faces you machine, solid pads under bores, critical faces vertical.

Hours = part mass ÷ real throughput (1.15 to 1.4 kg/h on our logged prints), plus 10 to 30% for travel and slow layers.
