Description

The world’s first HDPE filament with Low Warp technology.

Spectrum HDPE is a modern filament made from high-density polyethylene (HDPE) — one of the most durable and chemically resistant thermoplastics available on the market. It is among the first HDPE filaments in the world featuring Low Warp technology, making it suitable for reliable printing on desktop 3D printers. The innovative formulation developed by Spectrum ensures that HDPE, previously considered difficult to print, is now accessible to every 3D printing user.

A breakthrough technical filament with exceptional durability

Spectrum HDPE stands out for its balanced combination of moderate density (1.1 g/cm³), high strength, and excellent rigidity, making it a reliable engineering material for durable applications. HDPE characteristics makes it ideal for producing lightweight, high-strength structures. The filament offers a Rockwell hardness of 80 HRM, heat resistance exceeding 110°C, and excellent dimensional stability, providing strong layer adhesion and outstanding abrasion resistance.

Durability and resistance you can rely on

Spectrum HDPE features high impact strength, excellent wear and crack resistance, and very low moisture absorption, ensuring long-lasting printed parts. Due to its resistance to acids, bases, oils, and solvents, it performs exceptionally well in industrial, laboratory, and technical environments. Additionally, the material is UV-stable, non-flammable, and fully recyclable, making it both versatile and environmentally friendly.

Versatility and functionality

Beyond its technical and structural applications, Spectrum HDPE can also be used as a cleaning filament, effectively removing material residues from the 3D printer’s nozzle.

PETG ESD - Professional ESD Protection and Safety for EX Zones.

PETG ESD - Professional ESD Protection and Safety for EX Zones.

Professional ESD Protection and Safety for EX Zones.

Spectrum PETG ESD is a high-quality antistatic filament developed on the basis of a proprietary polymer blend designed to provide durable protection against electrostatic discharge (ESD). The material is intended for industrial and technical applications where reliability, safety, and precise surface properties are essential. It combines the mechanical strength typical of PETG with excellent layer adhesion and printability, while offering a unique matte surface finish that gives printed parts a professional appearance.

Unlike standard PETG filaments, Spectrum PETG ESD uses a permanent, non-migrating antistatic formulation whose performance is independent of ambient humidity. This means the material maintains its ESD-protective properties in both dry and humid industrial environments, ensuring consistent and safe protection of electronic components throughout their service life.

How Spectrum PETG ESD works

ESD (Electrostatic Discharge) is a phenomenon of sudden discharge of static electricity, which can damage sensitive electronic systems. Spectrum PETG ESD effectively prevents such discharges, ensuring that 3D-printed parts made from this filament are safe for use in contact with electronic devices and measuring equipment. The 3D-printed parts made from Spectrum PETG ESD exhibit a surface resistivity in the range of 10⁷–10⁹ Ω/sq, corresponding to the levels typically required for ESD (Electrostatic Discharge protection) and EX / ATEX safety, i.e., applications in potentially explosive environments.

The achieved resistivity values place Spectrum PETG ESD in the optimal functional range for ESD-safe materials, ensuring effective and controlled dissipation of electrostatic charges without the risk of sparking. The electrostatic energy is dispersed in the form of low-energy corona discharges, guaranteeing full safety of electronic components even in the absence of grounding.

Key Advantages

  • Surface resistivity: 10⁷–10⁹ Ω/sq (ESD & EX safety range)
  • Permanent, non-migrating antistatic protection
  • ESD properties independent of ambient humidity
  • Halogen-free formulation – environmentally friendly
  • High stiffness and precise surface quality
  • Easy processing typical of classic PETG
  • Excellent interlayer adhesion and low shrinkage

Applications

  • Housings, mounts, and covers for electronic devices
  • Accessories and tools used in ESD-protected areas
  • Measuring instruments and service components
  • ESD-safe trays, containers, and handling tools
  • Prototypes and parts requiring permanent electrostatic protection
  • Components and measuring equipment for EX / ATEX environments
  • Assembly parts used in the chemical, energy, and automotive industries

PLA ESD Filament - designed for ESD protection

PLA ESD Filament - designed for ESD protection

PLA ESD Filament - designed for ESD protection.

Spectrum PLA ESD is a modern, antistatic 3D printing filament based on a modified PLA biopolymer that provides permanent protection against electrostatic discharge (ESD) and sparking in explosive (EX / ATEX) environments. The filament has been developed for applications where electronic safety, print precision, and ease of use are crucial. Spectrum PLA ESD combines the eco-friendly nature of PLA with protective properties, offering high stiffness, excellent surface quality, and fully predictable printing performance.

Unlike standard PLA filaments, Spectrum PLA ESD uses a permanent, non-migrating antistatic formulation which effectiveness is independent of ambient humidity. The filament maintains its protective properties in both dry and humid environments, ensuring stable and long-lasting protection of electronic components. This makes PLA ESD an excellent choice for precise industrial, laboratory, and service applications.

How Spectrum PLA ESD works

Electrostatic discharge (ESD) occurs when electric charges accumulate on the surface of a material, potentially damaging sensitive electronic circuits. Spectrum PLA ESD effectively eliminates this risk by safely dissipating static charges in a controlled manner. 3D-printed parts made from Spectrum PLA ESD demonstrate surface resistivity in the range from 10⁷ to 10⁹ Ω/sq, which corresponds to typical for ESD (Electrostatic Discharge) protection and suitable for EX / ATEX safety, i.e., applications in potentially explosive environments.

These resistivity values place Spectrum PLA ESD within the optimal functional range for ESD-safe materials, ensuring effective and controlled dissipation of static charges without the risk of sparking. Electrostatic energy is released as low-energy corona-type discharges, ensuring full protection of electronic components even without grounding.

Advantages of Spectrum PLA ESD

  • Surface resistivity: 10⁷–10⁹ Ω/sq (ESD & EX safety range)
  • Permanent, non-migrating antistatic protection
  • ESD performance independent of ambient humidity
  • Halogen-free, environmentally friendly formulation
  • High stiffness and precise surface quality
  • Easy printing typical of standard PLA
  • Excellent interlayer adhesion and low shrinkage

Applications

  • Housings, holders, and covers for electronic devices
  • Tools and accessories used in ESD-protected zones
  • Measuring instruments and service components
  • Trays, containers, and tools for ESD-safe areas
  • Prototypes and parts requiring permanent electrostatic protection
  • Components and measuring tools for EX / ATEX environments
