Depending on the component size and orientation within the installation space, tolerances range from 0.1 mm to 0.3 mm. Please refer to our manufacturing tolerances for further details.

Overhangs: Depending on the material, overhangs with angles ranging from 42° (AlSi10Mg) to 45° (steel) can be printed parallel to the build platform. Overhangs smaller than 42° generally always require support structures. In the case of small areas, such as channels within drill holes (diameter up to approx. 8 mm), these areas are largely self-supporting. Channels: Depending on the material used, channels with a diameter of up to 8 mm can be printed without supports. It is important that the channels are accessible so that loose powder can be completely removed. We recommend designing channels of larger dimensions in a teardrop or diamond shape. Please contact us directly regarding this. Internal geometries: These can be printed provided the specifications regarding overhangs are followed. It is important to include appropriate openings for removing loose powder. Material jumps: Material jumps should be avoided, as high stresses occur in these areas and can lead to quality issues. Solid areas are prone to sink marks, while thin, large-area walls are prone to warping. Minimum wall thicknesses: Depending on the material, the selected layer thickness, and the print orientation, minimum wall thicknesses of up to 0.5 mm are achievable. Warping: Please avoid very long and thin components, as they are prone to warping.

Fine details and lettering can be reproduced, but should ideally run in the direction of printing.

Build volumes of up to 400 x 400 x 360 mm (steel) are available. For aluminum (AlSi10Mg), titanium, and Inconel, the maximum build volume is 280 x 280 x 360 mm. For bronze, we offer maximum dimensions of 80 mm in diameter and 80 mm in height. Please note that maximizing the use of the build volume for a part involves high costs, and the design should be optimized for the manufacturing technology. Otherwise, this will result in quality limitations coupled with very high part costs. Please take our design recommendations into account and feel free to contact us directly.

Blasting, vibratory finishing, mechanical finishing (turning, milling), electropolishing, wire EDM, painting.

2–4 business days for express delivery of AlSi10Mg, 6–8 business days for stainless steel/bronze, and 14 business days for specialty materials such as Inconel and titanium. Please refer to our current information in the online tool.

Support structures are used to compensate for internal stresses, dissipate heat, and support overhangs, making them essential for metal 3D printing.

Surface roughness is influenced by the orientation within the build volume, the attachment of support structures, and numerous other factors. Surfaces facing upward in the direction of printing are generally smoother and exhibit lower roughness values. The Rz values typically range from 35 to 100 µm in their untreated state.

Wall thicknesses of 0.5 mm can be modeled for bronze and aluminum. For all other materials, the minimum wall thickness is 1 mm.
