Simulation software to predict & correct warpage or cracking during the sintering process
Live Sinter™, developed by Desktop Metal, is a breakthrough simulation software designed to reduce the trial and error often involved in the sintering process of the metal 3D printed parts made with the binder jetting additive manufacturing process. Rather than printing a part straight to have it warp out of spec, Live Sinter prints an oppositely warped part that will sinter to meet dimensional tolerances.
Decades-old sintering challenges
Sintering remains one of the main challenges to the broad adoption of metal binder jetting technology. However, it is used in metal injection molding or pressed and sintered to fabricate millions of parts each year. Desktop Metal’s advanced simulation software team designed Live Sinter to eliminate the trial and error required to achieve high-accuracy parts via powder metallurgy-based additive manufacturing processes.
The compounding dynamic forces represent the typical unwanted situations during the sintering process, and those are:
- Part deformation
- Stress concentration
- Varying densities

Optimized Support Generation & Surface Offsetting
Live Sinter provides optional support generation optimized to significantly reduce material usage while enabling distortion compensation to occur where needed. Users interactively generate supports in various sinter orientations while analyzing support volumes and stability characteristics as part of a trade-off analysis. Surfaces to be offset for downstream machining operations may also be specified for integrated manufacturing operations.
Scan-Based Adjustment for Fine Tuning
Scan adjustments work over the volume of the part, ensuring that thin walls and hidden interior regions move in concert with exterior regions. Live Sinter enables correcting for complex distortion effects, yielding parts that consistently fall within 1% of the target dimension with as low as +/- 0.3% deviation. Parts may be scan adjusted multiple times to reach higher levels of accuracy.
