# What filament should I use for electronics enclosures?

The comments are about a printer enclosure, not a case around a hot board. One comment printed those parts in black PLA and says that person is not dealing with temperatures above 100f or much load. Two comments say PLA softens in a closed box while you are printing it. PETG and ASA temperatures here are print settings. They are not a clearance for an enclosure next to heat.

An electronics enclosure and a printer enclosure are different heat problems. The comments are the second one: printed parts that hold a printer box, and PLA that softens while the printer is closed. [Heat resistance](/answers/heat) is how hot a finished part can get before the published deflection numbers. [ASA printing](/answers/asa_print) and [polycarbonate](/answers/pc) are the hotter print windows. [Printer enclosure parts](/answers/enclosure_parts) is the hardware those comments are actually about.
## Settings on the rows

[Bambu PLA Basic](/brand/bambu-lab/pla-basic) lists 190–230 °C (374–446 °F), a bed of 35–45 °C (95–113 °F), and drying at 50 °C (122 °F) for 8 h, sheet checked 14 October 2026. [PolyLite PETG](/brand/polymaker/polylite-petg) lists 220–250 °C (428–482 °F) and a bed of 70–90 °C (158–194 °F) in the Open Filament Database, dataset imported 13 October 2026, and drying at 65 °C (149 °F) for 6 h on the technical data sheet, drying checked 18 October 2026. [Bambu ASA](/brand/bambu-lab/asa) lists 235–260 °C (455–500 °F) and a bed of 90–110 °C (194–230 °F) in that same database import, and its sheet checked 18 October 2026 stores drying at 80 °C (176 °F) for 8 h. No safety certification is listed. PLA is first because the three-year comment names it. The order is not a ranking for a case around a board.
