Why are PETG supports so hard to remove?

PETG bonds to itself, so its supports fuse across the default 0.2 mm gap. Raise Top Z distance 0.05 to 0.1 mm at a time, or print the interface in PLA at 0 mm.

Answer·Materials·November 7, 2026

Which support interface material works with each filament?

Print only the interface in a material that won't bond: PETG under PLA, PLA under PETG, ABS or ASA under nylon. Makers then allow a 0 mm top Z distance.

How do you remove stringing from a 3D print?

Pull or cut the loose strings, then hit the fine wisps with a heat gun at about 200 °C for one or two seconds. Longer can deform PLA, which softens at 54 to 60 °C.

Answer·Troubleshooting·October 30, 2026

Why is PETG so stringy?

Shipped profiles run PETG 20 to 35 °C hotter than PLA, and its melt draws out into threads. Dry it, drop the nozzle 5 to 10 °C, and expect a few fine hairs.
