The Table will be a wood product composite, that I will do a report on during the construction phase. The Gantry will evolve into a molded, cored, Fiber Reinforced Epoxy, which will be fiber glass or carbon depending on test of actual machine. The first one will be used to make the subsequent ones and will probably not have all of the same style as the model.
Thanks for asking, the need for the engraving is part of a new product launch that will be in February.
