Analysis of dimensional performance for a 3-D open-source printer based in FDM technique

by Luigi Galantucci, Ilo Bodi, Jorgaq Kacani and Fulvio Lavecchia

Abstract

In this paper an analytical dimensional performance evaluation and comparison is illustrated, done on benchmarks manufactured using two different 3D FDM printers: an industrial system, and an open-source one (a modified Fab@Home Model 1 printer). Using a factorial analysis design of experiment (DOE), optimum process parameters were found to improve dimensional accuracy on rectangular test specimens, minimizing changes in length, width and height. Fab@Home printer demonstrated to be a good platform, simple, flexible and inexpensive.

3 thoughts on “Analysis of dimensional performance for a 3-D open-source printer based in FDM technique

  1. Can you explain and state why only two (Raster width and Slice height) of the three selected parameters are similar for the FDM 3000 machine and the Fab@Home Model 1?

  2. The post-processing of a part with a cleaning bath can alter the dimensions and superficial appearance of the part, so, generally, measurements must be carried out before post-treatments. Could you specify if, in your application, the built specimens were post-treated before dimensional measurements?
