Additional Info

Parts built from EOS CobaltChrome MP1 conform to the chemical composition UNS R31538 of high carbon CoCrMo alloy. They are nickel-free (< 0.1 % nickel content) and are characterized by a fine, uniform crystal grain structure.

As built EOS CobaltChrome MP1 meets the chemical and mechanical specifications of ISO 5832-4 and ASTM F75 for cast CoCrMo implant alloys, as well as the specifications of ISO 5832-12 and ASTM F1537 for wrought CoCrMo implants alloys except remaining elongation. The remaining elongation can be increased to fulfil even these standards by high temperature stress relieving or hot isostatic pressing (HIP).

Min Supported Wall Thickness A supported wall is one connected to other walls on two or more sides.	0.9 mm
Min Unsupported Wall Thickness An unsupported wall is one connected to other walls on less than two sides.	1 mm
Min Supported Wires A wire is a feature whose length is greater than five times its width. A supported wire is connected to walls on both sides.	0.9 mm
Min Unsupported Wires A wire is a feature whose length is greater than five times its width. An unsupported wire is connected to walls on less than two sides.	1 mm
Min Hole Diameter The accuracy of a hole not only depends on the diameter of the hole, but also on the thickness of the wall through which the hole is printed. The thicker the wall section, the less accurate the hole becomes. Through holes must also allow for line-of-sight clearance to ensure all material is cleared during post-processing.	1 mm
Min Embossed Detail A detail is a feature whose length is less than twice its width. The minimum detail is determined by the printer’s resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Details that are too small can also be smoothed over in the polishing process. To ensure details come out clearly, make them larger than the indicated minimum. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.	0.6 mm
Min Engraved Detail A detail is a feature whose length is less than twice its width. Engraved or debossed details go into a surface.	0.6 mm
Min Clearance Clearance is the space between any two parts, walls or wires. To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. You can also try a material with a smaller minimum clearance.	1 mm
Min Escape Holes Escape holes allow unbuilt material inside hollow products to be removed. Normally you don’t need to consider this, our technician will add escape holes before printing. When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it.	0 mm
Interlocking/moving or enclosed parts? Sometimes the interlocking/moving parts can’t be printed, since the supports inside the cross section can’t be removed.
Require Support Material? Because each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.	Yes

Material Spec Sheet

DMLS Cobalt Chrome is 3D printed using SLM/DMLS (Selective Laser Melting) technology.

Selective Laser Melting creates objects from thin layers of powdered material by selectively melting it using a high power laser. The process takes place in a low oxygen environment in order to reduce thermal stresses and to prevent warping.

Industrial metals are best used for high-tech, low-volume use cases from prototyping to creating end-use parts. Metal 3D prints are comparable to traditionally manufactured parts in terms of chemical composition, mechanical properties (static and fatigue) as well as microstructure.

Once the printing is done, the extra powder that was not bound, and is not part of your design, is removed. Your part is now solid metal, and after the flutes are manually removed, it is tumbled and polished to produce a smooth finish.
