CRITT hosted the first roundtable of the day on the theme of Indirect Additive Manufacturing or “PIM like” of metal and ceramic parts. Here are the 5 speakers:
Today, FA “PIM like” 3D printing machine suppliers are multiplying and we have chosen to use one of them, Mr. Arnoul from Millenium, to present his new technology, the Markforged Metal X, a technology that has been present at the EPF in Troyes and at UTC recently, which makes it possible to print stainless steel and tool steels using FDM technology.
Then, we wanted to have feedback from the MIM-Alliance company that has been producing parts by the PIM process for almost 25 years and which has diversified towards the “PIM like”, the company, represented by its CEO, Mr Bihr tested FDM, extrusion and Binder jetting technologies to make parts directly into smaller series than into injection or for plastic injection molds.
Scientific input was provided by CNRS Lille, represented by Mrs Lecomte, with whom, at CRITT, we have just started a European project FABRICAR3V on indirect 3D printing with extrusion-type pellets.
Finally, to conclude this round table, we presented the experience feedback of a Troyes start-up, DI STUDIO 3D, represented by its director, Mr. Contat, who trains on 3D printing, sells printers and also produces parts. With this start-up, CRITT conducted investigations on FDM of filaments loaded, in which the CRITT-MDTS presented the first print results through the European project PEPS.
In conclusion, we learned that:
3D printing makes it possible to grow the parts around these holes as underlined by the CEO of Alliance, that the product becomes the process, that it allows us to become agile as well the research centers, the schools, companies than the laboratories, that we can today produce parts in additive manufacturing, that we can design the parts from the pixel, that is grain of powder and that productivity yields will become bigger and bigger especially with indirect manufacturing processes with cheaper process costs (purchasing, energy, tools, etc …)
