Models made in steel are printed in steel powder that is infused with bronze. Steel is the cheapest form of metal printing, very strong and suitable for very large objects.
The price for Steel is based upon the volume of the model:
Our pricing scheme is meant to encourage compact models. The more material inside the imaginary box (bounding box) around your model, the bigger your discount becomes for the same model volume. To know the real (discounted) price, upload your design.
A model is considered compact when the ratio between model volume and bounding box is 20% or more.
Sparse models, with a ratio below 7-8%, might get a penalty as the machine space they occupy will be decisive in the cost and not the cost of the material, which is directly linked to the model volume.
The price is first calculated in USD and then converted to EUR for non-US customers.

With steel 3D printing, your part is created by binding together layers of steel powder. Specifically, after a layer of steel powder is spread across the base of a “build box”, a special print head moves back and forth over the layer, and deposits binding agent at specific points, as directed by a computer and your design file. Once the layer is finished and it has been dried via powerful overhead heaters, a new layer of powder is spread, and the process begins again. In this way, layer by layer, from the bottom up, your part is created.
Once the printing is done, the build box is placed in a curing oven and your part is sintered. The extra powder that was not bound, and is not part of your design, is then removed. At this point, your part is still very fragile. This so called “green state” will be the base of some of the design rules and limitations that follow below. Finally, via the use of a flute system, your design is infused with bronze, which replaces the binding agent. Your part is now solid metal, and after the flutes are manually removed, it is tumbled and polished to produce a smooth finish.
