FDM Technology works with specialized 3D printers and production-grade thermoplastics to build strong, durable and dimensionally stable parts with the best accuracy and repeatability of any 3D printing technology.
Stratasys founder Scott Crump invented FDM Technology more than 20 years ago, and Stratasys has continued to lead the 3D printing revolution ever since.
How accurate are 3D FDM Printers?
Remember that a 3D printer works by depositing raw material layer by layer along the X, Y and Z axis. The accuracy of the 3D printer therefore depends upon the minimum distance the nozzle can travel vertically (the Z axis). Minimum the distance it can move, more the points along the sinusoid that it can capture, and better the accuracy.For Stratasys 3D printers, which are the pioneers of the FDM printers, the current best possible dimensional accuracy is about 0.127 mm. Of course, the choice of raw material too plays an important part in achieving dimensional stability. It should also be remembered that the accuracy comes at the cost of printing time required.
