  Abstract

  The manufacture of curing tools for composite materials using 3D printing represents an innovative, rapid, and economical solution, especially for small production runs. It is an efficient alternative to traditional machining, although its influence on the mold must be known. A method for manufacturing high-temperature laminating tools is proposed, based on a 3D printed model and short fiberglass-reinforced epoxy resin, which allows its use at temperatures up to 160 °C. The influence of the tool will be studied through a dimensional analysis of the geometric variations of the model throughout each stage, from 3D printing to the post-curing required for working at high temperatures. The results of this analysis will be discussed and will allow the development of compensation techniques to minimize deviations between the final part and the nominal geometry and the reduction of residual stresses to improve the precision and repeatability of the process.
