German company LAY-Filaments has launched an improved version of its waxy 3D printing filament Moldlay. Moldlay is used for casting processes based on 3D-printed models.
According to LAY-Filaments, the revised MOLDLAY250° already flows out of the mold at 230 to 250 degrees Celsius. It thus behaves like liquid wax. In conventional ovens, models can thus be removed from the mold. Other filaments for this application, on the other hand, have to burn at over 500 degrees.
According to the manufacturer, MOLDLAY250° is also characterized by optimum dimensional stability. It can be processed without a heated print bed because no deformation occurs. This reduces printing costs, especially for large parts. In addition, it is suitable for sculptures because no warping occurs.
MOLDLAY250° will be available from September. It can be used for two common casting processes: In lost-wax casting, the model is coated with a heat-resistant material. After the filament is heated and flows out, the negative mold remains for casting. Permanent mold casting uses a reusable mold.
According to LAY-Filaments, MOLDLAY250° is the only filament that does not require high temperatures for burnout. Other materials have to be heated in special ovens at up to 600 degrees for this, which causes unpleasant emissions. MOLDLAY250° enables a clean and energy-efficient casting process and is particularly interesting for artists.
