      What is the speed of the printer?

      The maximum build rate of the Studio System™ printer is 16 cc/hr. The average print rate (inclusive of acceleration and deceleration, printhead switches, etc.) is approximately 6 cc/hr when printing with the "standard" print profile at 150 μm layer height.

      How do supports work?

      Desktop Metal’s Fabricate™ software automatically generates support structures required to stabilize your part during both printing and sintering. The software also automatically creates a Ceramic Release Layer™ in between the part and its supports, both of which are printed in metal. The Ceramic Release Layer is deposited with a second printhead during printing and enables the fabrication of complex geometries and multi-component assemblies as it resists sintering in the furnace, allowing for easy, manual separation of the part from its supports after sintering.

      Does shrinkage depend on the material?

      Shrinkage in the Studio System™ process occurs during the sintering step and depends on the material. That said, regardless of material, parts are typically expected to shrink in size by about 15%. Shrinkage is relatively uniform, with slightly more shrinkage in the z-direction (as printed).

      Fabricate™ software calculates estimated shrinkage based on the selected material and print profile, and automatically applies the appropriate scaling factor to the model before printing.

      What is the role of infill?

      Most parts printed with the Studio System™ contain infill, which not only reduces print and debind time, but also enables lightweighting -- a key advantage of additive manufacturing. With the Studio System™, users have the ability to adjust infill spacing using the custom settings in Fabricate™ software. Reducing the space between infill toolpaths increases part strength and fabrication time while increasing infill spacing results in a reduction in part weight and fabrication time. Parts that have thicknesses less than 8.5 mm can be printed without infill by using an increased shell thickness.

      Can parts be machined after sintering?

      Yes, sintered parts out of the furnace can be post-processed similar to parts manufactured via traditional methods, including machining, heat treating, welding, grinding, etc. If your application requires specific tolerances for critical features or surfaces, you can do a quick machining operation to achieve those on the sintered part.

      What is the atmosphere in the furnace?

      The Studio System™ furnace sinters parts under vacuum with low flow rates of inert gas. Depending on the material, the gas used by the furnace to achieve this environment may either be an argon / hydrogen forming gas, or pure argon. Sintering under vacuum allows for high material densities and consistent material chemistry while using a minimal amount of inert gas.

      What are part tolerances?

      Tolerances for the Studio 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 types of parts are best suited for the Studio System?

      Generally, if a part costs > $200 to manufacture using traditional methods or takes a few weeks to obtain via outsourced manufacturing, is needed in low volumes, or is difficult to machine (e.g. needs a 5-axis machine or multiple fixturing set ups) then it is probably a good candidate for the Studio System™. One other great criterion is any part that may eventually be die cast or sand cast in larger volumes — these parts are great to prototype on the Studio System and eliminate the need for upfront tooling.
