![]() The use of sintering supports, while effective in controlling a part’s deformation, also constrain the part from achieving its naturally-desired shape, resulting in a higher concentration of stress points. In the absence of this type of simulation technology, many powder-metal manufacturers rely on static sintering supports to control shrinkage. By contrast, geometries generated by Live Sinter are printed intentionally to aid the transformation that occurs during sintering, instead placing the part in a state of compression while it shrinks, reducing the chance of cracking. This tension results in a greater likelihood of cracking and internal fractures. Typically, a part during sintering experiences tension and various other forces during densification when particles resist mass transport within the part. In addition to generating parts with more reliable dimensional accuracy, Live Sinter also renders parts of higher quality.
