Nebula PETG V0 FR Black 1 kg

Product Description

Nebula PETG V0 FR Black 1 kg is a technical filament based on PETG enriched with flame retardants. Thanks to this, it combines the classic properties of PETG – easy printing, high strength and durability – with significantly increased fire safety. The material is designed to meet the UL94 V0 flammability class*, which means that when ignited in a vertical position, it extinguishes quickly and does not spread the flame.

This filament is intended for functional and long-term stressed parts, especially where they may be exposed to elevated temperatures, electrical components or the risk of sparks. The black variant offers an elegant appearance, covers the internal structures of the print well and is suitable for covers, boxes, jigs, cable holders and switchboards.

Note: To achieve the required flammability properties, it is necessary to print within the recommended temperature range and on a well-tuned printer.

Key Features

• Self-extinguishing PETG (FR – Flame Retardant) – the material is designed to meet UL94 V0*, suitable for applications with requirements for higher fire safety.
• High mechanical resistance – strong, tough and impact resistant, suitable for mechanically stressed parts.
• Thermal resistance – thanks to PETG modification, the material is suitable for environments with increased temperature compared to regular PLA.
• Low shrinkage and good dimensional stability – suitable for precise parts and larger prints, reduces deformation and warping.
• Easy printing on common FDM printers – a closed chamber is not necessary, a heated bed is sufficient.
• Universal black color – elegant technical appearance, ideal for electronics covers, instrument cases and functional components.
• Standard 1 kg spool, diameter 1,75 mm – compatible with most desktop 3D printers.

Recommended Use

Nebula PETG V0 FR Black is an ideal choice for:

• electronics covers and housings (control units, power supplies, switchboards)
• holders and jigs near heat sources or electrical equipment
• technical parts for automotive, industry and hobby projects where increased safety is required
• components with a requirement for thermal and chemical resistance
• functional prototypes and small series of spare parts

Printing Recommendations

Specific values may vary by printer, but for PETG V0 FR the following ranges usually prove successful:

• Nozzle temperature: approx. 235–260 °C
• Bed temperature: approx. 70–90 °C
• Print speed: medium speeds, typically 30–70 mm/s
• Cooling: rather lower to medium (to avoid worse layer bonding), around 0–50 % depending on geometry
• Chamber: closed chamber is not necessary, but can improve the quality of larger prints
• Adhesion: use of a suitable adhesive layer (PEI, glue stick, adhesive spray) is recommended for secure print holding

It is recommended to dry the filament before printing to minimize stringing, bubbles and surface degradation.

Technical Parameters

* UL94 V0 is a laboratory test method for classifying the flammability of plastics. For printed parts, actual properties depend on print settings, geometry and infill density.

Advantages over common PETG and PLA

• Safety: thanks to self-extinguishing properties, it is more suitable for proximity to electronics and heat sources.
• Better thermal resistance than PLA: parts deform less at higher temperatures (e.g., in switchboards, technical cabinets).
• Higher toughness than PLA: suitable for impact-stressed and functional parts.
• Still relatively easy printing compared to materials like ABS, PC or nylon.

Safety and Storage

• Ensure sufficient ventilation of the workspace during printing.
• Store the filament in dry conditions, ideally in a resealable box with desiccant.
• Protect from direct sunlight and high humidity to maintain print quality as well as mechanical and self-extinguishing properties.

Nebula PETG V0 FR Black 1 kg is a great choice for users who want a reliable technical filament with a higher level of safety without having to sacrifice typical PETG printing comfort.
