Dimensional accuracy of 3D printed parts

This commodity presents the expected dimensional accuracy of parts produced via 3D printing and discusses why part inaccuracies occur.

Metal printing (specifically DMLS and SLM) apply a laser to selectively sinter or melt metal powder to produce metal parts. Much similar SLS, metal printing produces parts one layer at a fourth dimension in a controlled, heated environment on industrial-sized machines. This layer-by-layer construction coupled with the very high temperatures involved in the process creates farthermost thermal gradients, and the net effect is that stresses are built into the part.

As a event, metal printed parts are at a high take a chance of distorting or warping, significant good design practices and part orientation are critical to achieving an accurate part. Dissimilar SLS, support structures are vital to minimize distortion of the part during production. Parts are also mostly congenital upon a solid metal plate and need to exist removed one time the print procedure is complete. A sound understanding of the process is required along with solid and lattice back up structures to keep the part deeply attached to the print bed and cease information technology from detaching. About parts are also stress relieved (via a heat handling process) after they're built and before removal from the build plate (doing so allows the crystalline structure to relax, preventing failure afterward).

Since the price of metal 3D printed parts is high, simulations are ofttimes used to validate the accuracy of a design, earlier starting the impress job.

Dimensional tolerance	± 0.1 mm
Shrinkage/warping	Parts at a high run a risk of shrinkage or warping. Bracing and support are used to help reduce the likelihood of this occurring.
Support requirements	Essential to achieve an accurate part.
