GMASS™ is an excellent choice for rapid prototyping in applications that require weighting, balancing, or radiation shielding: Consumer ? Sporting goods, add weight, balancing Healthcare ? Medical x-ray shielding, nuclear medicine components, laboratory equipment Industrial ? Industrial x-ray shielding, reactor shielding, vibration dampening, inertial weighting It offers the ability to rapidly prototype high-density components. Using a variety of metallic fillers, this material has density approaching traditional metals, while offering the design flexibility of ABS plastic. Now your plastic parts can have the weight and feel of metal castings! Colored filament is available in limited configurations to allow further design enhancements. The non-toxic fillers in GMASS™ make it an excellent choice for radiation shielding without the environmental impact of lead. While designed for rapid prototyping, GMASS™ also makes an excellent material for low-quantity additive manufacturing processes. Filament diameter: 1.75 +/- 0.10 mm Base material: ABS Plastic Filler material: Proprietary compounds of bismuth and tungsten Density Range: 2.7 +/- 0.1 g/cc for bismuth, 4.0 +/- 0.2 g/cc for tungsten Note that stated densities are for the filled filament material. Printed part densities may vary due to printer processing parameters, and should be confirmed by the user prior to use. PROCESSING NOTES Recommended printing temperature: 230C Recommended printing speed: 40 ? 90 mm/s We recommend using a heated bed: 100 ? 110C Advised nozzle size: 0.5 - 0.6 mm Note: The filament will have a higher likelihood of clogging smaller nozzles such as 0.4mm and smaller because of the tungsten particles. Therefore a larger size nozzle is recommended. RECOMMENDATIONS: A heated bed should be used to prevent warping The tungsten in the filament will wear down the brass nozzle after several hours of printing. Check nozzle before each print and replaced if worn. To ensure proper adhesion to print bed, a small amount of ABS slurry can be applied to the bed before starting to print. To achieve maximum density, you may need to increase the flow rate about 5 ? 10%. We have also found that using a larger nozzle but using a 0.4mm size nozzle in the software settings will give you better density. Note: Print at 100% in-fill to achieve full density on your printed parts. Only $95.45 - Click here to buy now! |
