What software is required for the Shop System™?
Desktop Metal will provide build prep software for use with the Shop System™ that facilitates uploading parts, generating supports, nesting builds, and slicing as well as sending files to the printer for processing. Customers will be able to use leading third party additive manufacturing build preparation tools (e.g., Materialise, Autodesk, and more) and import nested build boxes into the Shop System™ software. In the future, we anticipate supporting direct integrations for third party software tools to the printer, although this will not be available at launch.
What is the maximum part size?
Theoretically, the entire Shop System™ print bed can be printed as one part, a 350 x 222 x 200 mm block (for the 16L Shop System™ printer configuration). However, larger parts are (i) more delicate to handle in the “green state” after printing and (ii) more likely to distort and/or crack during sintering. For best results during printing and sintering, we recommend limiting the part size to 150 x 100 x 50 mm.
How much shrinkage occurs during the sintering process?
Shop System™ parts experience shrinkage during the sintering of roughly 15-20% depending on the geometry and the dimensions. Shrinkage is calculated and automatically compensated for in the accompanying Shop System™ build preparation software.
Are supports required?
Supports (or "setters") are not required for the Shop System™ binder jetting process — during printing, parts are supported by the loose powder in the build box.
However, depending on the part geometry (for example, parts with large overhangs), setters may be required during sintering in order to maintain tolerances and minimize the likelihood of distortion or cracking. Customers can use the Shop System's build preparation software to generate supports automatically — in this scenario, customers can print the software-generated “live” metal supports in conjunction with the parts in the build box, and they will shrink along with the parts during the sintering process.
For larger quantity parts or for parts that may not require a significant amount of support, reusable ceramic setters (similar to those used in metal injection molding processes) may be a more economic alternative than printing “live” metal supports -- although these must be designed and manufactured separately.
What are part tolerances?
Tolerances for the Shop System™ will be similar to casted steel parts. If an application requires specific tolerances for critical features or surfaces, parts can be easily and quickly machined (e.g. using a bridgeport) after sintering.
What are the compatible materials?
The Shop System™ will support a broad range of metals, ranging from stainless steels to tool steels and other super alloys. At launch, 17-4PH Stainless Steel will be qualified for use with the Shop System™ and available for purchase from Desktop Metal or Authorized Resellers.
Are third party materials allowed?
The Shop System™ is a turnkey solution including everything you need to go from digital file to sintered metal part — software, hardware, and consumables. Desktop Metal metal powders and proprietary binders are engineered to maximize print repeatability while optimizing yield and sintered part properties. To ensure system performance and part quality, the Shop System™ will only support consumables (including metal powder, binder, and printheads, among others) purchased from Desktop Metal or Authorized Resellers. Any use of third party consumables or materials may void the Shop System™ warranty.
Are there facilities requirements?
The Shop System™ prints using loose metal powder, so adequate ventilation is required in addition to the power, electrical, and other physical / interface requirements set forth in the Shop System™ Site Prep Guide. Companies are required to design facilities to meet all local, regional, national building code, fire code, and Environmental Health and Safety (EHS) requirements. Adequate ventilation takes into consideration these applicable requirements as well as room layout, existing equipment on hand, materials processed, and procedures utilized, in addition to the specific requirements of the equipment provided by Desktop Metal.
