Prototype tool & precision modeling

REN Shape 460 is a moderate density precision modeling board that features a lower coefficient of thermal expansion to provide enhanced dimensional stability over a broader temperature range than other modeling boards. REN Shape 460 provides the same excellent definition and accuracy for which the REN Shape family of products is well-known. Machinable with carbide cutters, REN Shape 460 offers ultra-fine surface finish, outstanding resistance to shrinkage and warping and superior reproduction of intricate detail.
