Homebuild Smoothing Tumbler for 3D Printed Parts

Mancave developed this simple to build tumbler for smoothing 3d printed parts. It works best with metallic filaments like Bronzefill and simillar. It tumbles the part with small screws giving it shiny and smooth surface.

Here is the build and operation video:

GMASS tungsten and bismuth filled high density ABS filament

GMASS is a new filament with high density ABS as main component with added tungsten or bismuth metal particles.

Only limited information is available without any tests or detailed review. There are almost no pictures of it.

GMASS is priced at 95 USD range for 0,5 kg spool.

From GMASS product page:

GMASS™ is a patent pending specially-formulated high-density ABS-based filament for 3D printing applications. It offers the ability to rapidly prototype high-density components. Using a variety of metallic fillers, it has a 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.

Possible applications:
Consumer – Sporting goods, add weight, balancing
Healthcare – Medical x-ray shielding, nuclear medicine components, laboratory equipment
Industrial – X-ray shielding, reactor shielding, vibration dampening, inertial weighting

Specifications:
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.

What is a price of Sciaky machines? Well, If you have to ask you can not afford it. They do not list the prices which is common practice among industrial equipment manufacturers.

Update (15.5.2015.):

Sciaky announced a release of several new electron beam 3d printers for industrial applications. next to their well known flagship large volume EBAM 300 series, Sciaky has released the EBAM 150, 110, 88, and 68, with nominal part volumes all listed below:

EBAM 150: 146” (3708 mm) wide x 62” (1575 mm) deep x 62” (1575 mm) high
EBAM 110: 106” (2692 mm) wide x 47” (1194 mm) deep x 63” (1600 mm) high
EBAM 88: 84” (2134 mm) wide x 35” (889 mm) deep x 63” (1600 mm) high
EBAM 68: 64” (1625 mm) wide x 25” (635 mm) deep x 63” (1600 mm) high
