PETG
A thermoplastic polyester material modified from PET, offering good toughness, chemical resistance and interlayer adhesion; it is commonly used in 3D printing and has a glass transition temperature of approximately 80°C.
Timeline (last 90 days)
Glass-fiber PETG is a reinforced filament made by mixing chopped glass fibers into ordinary PETG; it improves rigidity, heat resistance and dimensional stability, but accelerates nozzle wear, so wear-resistant hotends such as hardened steel or ruby are recommended, and printing temperatures typically need to be around 250-260°C.
The Homelab rack was entirely 3D-printed using PETG material on a Bambu Lab X2D printer, with the design from Ilan Kushnir.
Structural parts printed in PLA or PETG are low-cost and allow flexible iteration, but are inferior to metal in rigidity and durability.
PLA has poor heat resistance and softens at approximately 60°C; PETG balances printability and toughness; TPU is elastic and suitable for flexible parts.
PLA has poor heat resistance (softening at approximately 60°C) and is unsuitable for parts under long-term stress; PETG balances printability and toughness; TPU is elastic and suitable for making flexible parts.
Desktop 3D printer prices have dropped to the 1,000–3,000 RMB range, and materials such as PLA and PETG can meet the strength requirements of most non-load-bearing assistive devices.
