About Aluminum (AlSi10Mg) – 3D Printing Material
Aluminum 3D printing material is both lightweight and strong, recommended for functional parts requiring durability, stiffness, and high accuracy. Aluminum 3D printing relies on Selective Laser Melting (SLM) technology. Aluminum or 3D printed aluminum (alloy AlSi10Mg, 10% Silicon 0.5% Mg) offers great corrosion resistance, making it an ideal material for outdoor applications, also providing high electrical and thermal conductivity. 3D printed aluminum can be machined, milled, and tapped too.
Color & Finishes
Standard
In certain areas the surface of 3D printed aluminum can be slightly rougher than others, due to where supports were added.

Design Guidelines
Bounding Box
Bounding Box Max
250 x 250 x 200 mm
Bounding Box Min
X + Y + Z > 30 mm
The bounding box is a 3D imaginary outline of a box that encloses the smallest area occupied by your model. Your model must be within the minimum and maximum bounding box sizes. If the size of the model is close to the maximum bounding box, then the printing orientation will be restricted.
Walls
Supported Wall Thickness Min
1.0 mm
Unsupported Wall Thickness Min
1.0 mm
Wires
Supported Wires Min
1.5 mm
Unsupported Wires Min

Escape Holes
Single Escape Hole Diameter (Min)
4.0 mm
Multiple Escape Hole Diameter (Min)
2.0 mm
A single escape hole at the end of a cavity will not allow material in the corners near the escape hole to fully escape. So we recommend multiple escape holes at both ends of the cavity.
Clearance
Min
0.6 mm

Accuracy
Accuracy
± 0.2 mm for 3D printed aluminum products under 10mm in all dimensions, ± 1.5% for 3D printed aluminum products over 10 mm in any dimension.
For example: a product with dimensions of 50 x 50 x 100 mm can be 0.015*100 mm = 1.5 mm bigger or smaller in any direction.
