Traditional 3D Printing materials such as PLA and ABS have limited technical capabilities due to the nature of the polymers. But now Michigan-based startup 3DXTech, a division of Global Polymer Group (GPG) wants to change it by developing innovative solutions to solve difficult those technical challenges.
Back in May, 3DXTech announces three specialty 3D printing filaments that can be used in existing FDM/FFF 3D Printers. Responding to the needs of this global market, 3DXTech today introduced another two new grades of Electrostatic Discharge (ESD)-safe materials that have been developed specifically for use in desktop 3D Printers.
3DXNano ESD filaments are made from engineering-grade polymers and incorporate multi-wall carbon nanotubes (CNTs) to achieve a highly consistent ESD-level of conductivity.
"Our 3DXNano ESD products will work in practically any desktop 3D printer with a heated build platform," says Matt Howlett, President of 3DXTech.
"We chose to incorporate CNTs into these products because they offer exceptionally consistent ESD properties with very low loading rates. This allows for the filament to be more ductile and have less particulate contamination compared to traditional carbon black additives. The base resins we used - ABS and PETG - are very familiar to the 3D printing community and suitable for most desktop 3D printers. Whereas ABS is suitable for the majority of applications, we needed a more chemically resistant polymer for applications where improved chemical resistance is needed. We chose PETG because it is a permanently amorphous polyester that exhibits very good chemical resistance, exceptionally low moisture absorption, and excellent dimensional stability."
Benefits of CNTs include:

  • Consistent surface resistivity
  • Low additive loading rates
  • Improved retention of impact & elongation
  • Low particulate contamination
  • Minimal contribution to outgassing and ionic contamination

3DXNano ESD ABS Carbon Nanotube

3DXNano ESD ABS Carbon Nanotube (CNT) enhanced compounds are used in critical applications that require electrostatic discharge (ESD) protection and a high level of cleanliness.
Recommended Print Conditions:

  • Extruder: 245-255°C. 3DXNano ESD ABS is a filled product and has a higher melt viscosity vs. unfilled ABS. Therefore, it is sometimes necessary to print at higher temperatures to allow the resin to flow properly.
  • Bed Temp: 100-110°C
  • Bed Prep: Kapton Tape, ABS/Acetone Slurry (we typically use both)

3DXNano ESD ABS + Carbon Nanotubes is priced at $58 / 750g (1.65 lbs) or $78 /kg (2.2 lbs).
