Product Guide, Usages & Technical Reference
Product Overview
Kingroon PETG Basic 1.75mm (Jet Black) is the quintessential workhorse filament for makers, engineers, and prototyping labs. Delivering a deep, satin-gloss black finish, it hides layer lines exceptionally well while offering industrial-strength mechanical properties that outlast standard PLA prints outdoors and under stress.
Kingroon uses premium raw PETG resin with advanced pigments that maintain consistent optical density without compromising melt flow or layer bonding. Ideal for professional enclosures, brackets, automotive accessories, and robotics assemblies.
- Satin jet-black finish masks layer lines and produces production-ready parts
- High tensile strength (approx. 50 MPa) and fatigue resistance under cyclic loads
- Excellent UV resistance; will not yellow, degrade, or become brittle under direct sunlight
- High chemical resilience against greases, oils, alcohols, and household detergents
- Tangle-free neat spool winding with tight ±0.02 mm tolerance
- Highly sensitive to ambient humidity; wet filament causes popping sounds and surface zits
- Can exhibit stringing over open travels if travel acceleration and retraction are low
- Highly aggressive adhesion to glass and smooth PEI beds without a separation layer
- Automotive Interior Accessories: Phone mounts, cup holder adapters, cable clips, and glovebox organizers.
- Robotics & CNC Components: Structural motor mounts, endstop brackets, sensor housings, and drag chain links.
- Workshop Fixtures: Tool holders, pegboard brackets, drill bit cases, and dust extraction ports.
- Production Enclosures: IoT gateways, electronic sensor housings, and rugged test enclosures.
Pro Tuning Tip: When printing black PETG for structural parts, drop print speed to 50 mm/s and run the hotend at 242°C. Lower speeds give the polymer chains more time to thermally weld, yielding near injection-molded break strength.
