Professional Lab PETG Copper / Bronze 1 kg

Professional Lab PETG Copper / Bronze 1 kg – durable PETG with an attractive copper-bronze effect

Professional Lab PETG Copper is a high-quality PETG filament with a metallic bronze shade, designed for reliable printing of functional components, prototypes, and design models. It combines the classic advantages of PETG – toughness, chemical, and thermal resistance – with an impressive look resembling copper/bronze.

Thanks to its wide printing range and stable diameter, it is suitable for beginners and advanced users, in home workshops, makerspaces, and smaller series production.

Main advantages and use

• High toughness and impact resistance – suitable for functional parts that must endure stress.
• Good thermal resistance – higher resistance than PLA, suitable for parts exposed to commonly elevated temperatures (interior, technical applications).
• Low shrinkage and warping during printing – ideal for larger objects and precise technical prints.
• Excellent layer adhesion – strong layer bonds, lower risk of cracking.
• Metallic bronze appearance – attractive surface for decorations, design models, cosplay, accessories, or presentation prototypes.
• Universal compatibility – suitable for most FDM/FFF 3D printers with a nozzle for PETG printing.

Typical applications:

• functional and technical parts (covers, holders, mounts, fixtures)
• prototypes and mechanical components
• design and decorative items with a metallic effect
• models and accessories for cosplay or props

Printing properties

Professional Lab PETG is designed to provide stable printing and consistent quality throughout the 1 kg spool.

Recommended print settings (typical range for PETG Professional Lab):

• Nozzle temperature: approximately 220–245 °C (recommended to start around 235 °C and fine-tune according to the printer)
• Bed temperature: approx. 70–85 °C depending on the bed type
• Print speed: approximately 40–60 mm/s for a quality surface with a metallic effect
• Cooling: low to medium (excessive cooling can degrade layer adhesion)

For best results, it is recommended to print on a clean, degreased bed (glass, textured PEI, glue stick, or special adhesive spray) and protect the filament from excessive moisture by storing it in a sealed container or dry box.

Appearance and surface

• Color: copper / bronze (copper, bronze metallic)
• Surface: slightly glossy metallic effect that highlights the contours of the model and creates a premium look.
• Particularly suitable for aesthetically demanding projects where attractive design is as important as function.

PETG material properties

• Material type: PETG (polyethylene terephthalate glycol)
• Characteristics:
  • higher toughness than PLA
  • better chemical resistance than PLA (resistance to common chemicals and cleaning agents)
  • lower shrinkage than ABS – easier printing without an enclosed chamber
  • suitable for functional prints and long-term use indoors

Compatibility

The filament is intended for FDM/FFF 3D printers using PETG and a standard nozzle (brass or hardened). The metallic bronze pigment does not have the character of an abrasive filler like actual metal composites, so a special hardened nozzle is usually not required – nevertheless, regular wear inspection is recommended.

Summary

Professional Lab PETG Copper / Bronze 1 kg is a great choice for anyone looking for a reliable PETG filament in an attractive copper-bronze shade. It offers a combination of mechanical durability, good thermal stability, and excellent printability, making it ideal for both functional technical parts and representative design prints.

Key features:

• Metallic copper-bronze look for attractive design prints
• Universal PETG for functional and aesthetic models
• High toughness and impact resistance compared to PLA
• Low shrinkage and good dimensional stability – suitable for larger parts
• Wide printing range and easy printability on most FDM printers
• Good resistance to common chemicals and elevated temperatures
• High-quality spool winding and stable filament diameter for reliable printing
