Why do my supports keep falling over?

Tall, thin supports on a small foot get knocked loose. Widen the first layer (OrcaSlicer 2 mm, PrusaSlicer 3 mm by default), thicken branches, turn on Z hop.

What bed temperature should you use for ABS?

Use 90 to 100 °C for ABS: Bambu Lab's range on PEI and Engineering plates. Prusa defaults to 100 °C, and the Bambu Lab P1S bed tops out at 100 °C.

What bed temperature should you use for ASA?

Set the bed to 100 °C for ASA, Bambu Studio's default. Data sheets run from 75 °C (Polymaker) to 110 °C (Prusa), always with glue and an enclosure.

Is the bed surface as hot as the temperature you set?

Usually not. Prusa puts its steel sheet about 5 to 10 °C below the heatbed sensor, and a thermal camera read 56 °C on a Prusa i3 MK3 bed set to 60 °C.

Does a higher bed temperature help adhesion?

Yes, up to a point: Prusa adds 5 to 10 °C when a material won't stick, but makers stop near the glass transition, 61 °C for PLA and 81 °C for PETG.

Bed temperature chart: what bed temperature does each filament need?

Bambu Lab sets PLA at 45 to 65 °C on PEI, PETG 60 to 80 °C, ABS and ASA 90 to 100 °C, PC and nylon 100 to 120 °C. Fiber-filled grades match their base plastic.

What bed temperature makes a print easiest to remove?

Let it cool: Prusa waits for room temperature and Bambu Lab for 35 °C or lower on textured PEI. On Bambu's SuperTack plate, reheat a stuck print to about 50 °C.

What happens if the bed temperature is too high?

The first layers stay soft and squash out into elephant foot; Polymaker caps PLA at 60 °C. Too hot also clogs nozzles and bonds PETG hard enough to tear PEI.

Does bed temperature affect warping?

Yes. In a 2021 ABS test, corner lift was lowest at a 90 °C bed, 0.89 mm, and grew both cooler and hotter: 1.65 mm at 80 °C, 1.37 mm at 100 °C.

Does PLA need a heated bed?

No. Prusa says PLA does not require a heated bed, and Polymaker and Overture start their bed range at 25 °C. Prusa still recommends a 60 °C bed.

How do you find the right bed temperature for a filament?

Take the bed range from the data sheet's recommended print settings, for your plate (Prusament PLA: 40 to 60 °C). Raise 5 to 10 °C if the first layer won't stick.

Should the first layer bed temperature be different from the rest?

Most slicer defaults use one bed temperature for all layers. PrusaSlicer starts PETG at 85 °C then 90 °C; OrcaSlicer starts ABS at 105 °C then 100 °C.

What bed temperature does nylon need?

Bambu Lab sets 80 to 100 °C for its nylons on a glued PEI or Engineering plate, Prusa 110 °C on a PA Nylon sheet. Polymaker's nylons run at 25 to 50 °C.

What bed temperature should you use for PETG?

About 70 to 80 °C. Bambu Lab lists 60 to 80 °C for all its PETG, Prusa runs 85 then 90 °C. Put glue stick on smooth PEI or glass first.

What bed temperature does polycarbonate need?

Polycarbonate needs a 90 to 120 °C bed. Bambu Lab lists 90 to 110 °C, Polymaker 90 to 105 °C and Prusament PC Blend 110 ± 10 °C; PC-ABS takes 90 to 105 °C.

What bed temperature should you use for TPU?

30 to 45 °C covers most TPU. Bambu Lab lists 30 to 35 °C for its 85A, 90A, 95A HF and 68D grades; Polymaker allows 25 to 60 °C and Prusa 60 to 75 °C.

What does bed temperature do in 3D printing?

It keeps the first layers stuck and stops them shrinking off the plate. Polymaker sets it just under the glass transition: PLA at 25 to 60 °C against a 61 °C Tg.

Do you need glue stick on textured PEI?

Not for PLA, PETG or TPU. Prusa requires a glue stick for ABS, ASA, nylon and PC Blend on textured PEI, and Bambu Lab says those four may need one.

How often should you wash a PEI build plate?

Wash it when prints stop sticking, not on a schedule. Prusa wipes with about 90% IPA and saves soap for a last resort; neither maker allows acetone on textured PEI.

Why did my print warp on only one corner?

One lifted corner has less grip or more cooling than the other three. Five causes to check: bed height, a draft, a cool bed zone, skin oil and a sharp corner.

Why won't TPU come off the build plate?

TPU welds itself to a hot bed, a squashed first layer or bare smooth PEI. Bambu Lab lists 35 to 45 °C on PEI plates. The causes, the fixes and a safe way to peel it.
