GMASS High-Density Tungsten Filled 4.0g/cc Sample - 100g
Metal-like Weight and Feel
High-density Tungsten Filled ABS (4.0g/cc)
GMASS™ is a specially-formulated high-density ABS filament for use in specialized 3D printing applications.
Developed by Turner MedTech, this patent pending ABS-based metal-filled filament offers the ability to rapidly prototype high-density components. By using high-density fillers, this product approaches the density of traditional metals, while still offering the design flexibility of ABS plastic.
According to Turner MedTech, the non-toxic fillers in GMASS make this an excellent choice for radiation shielding without the environmental impact of lead. The high metallic content may help attenuate EMI emissions when making 3D printed enclosures and shields for electronic devices.
When sanded and polished smooth, a solid printed piece with GMASS has the weight and feel of metal parts, giving a truer experience to prototypes of designs that ultimately will be made in metal.
This highest-density 4.0g/cc version of GMASS is offered in dark grey.
For simulating the density of aluminum parts, we also offer the 2.7g/cc version of GMASS in three different colors.
IMPORTANT USAGE NOTES
The metallic filler used to produce GMASS filament will lead to a much faster wear of the print nozzle (compared to standard non-filled plastics). To improve overall printing performance, Turner MedTech recommends the use of a larger nozzle diameter (0.5 to 0.6 mm). We offer high-lubricity nozzle replacements that come in both 0.4mm diameter and 0.6mm diameter.
