“…One of the ways to reduce the coefficient of friction between the stretch die and the workpiece is the production of stretch dies from plastics using fused deposition modeling (FDM technology). [9] Stretch dies obtained by this method are lighter and more repairable than stretch dies from recycled cast aluminum. [5] There is practically no waste in the production of stretch dies from engineering plastics using the FDM 3D printing method, while the production cycle of traditional products from recycled cast aluminum involves milling the working surface and the base bottom surface mounted on the frame or plate.…”

The paper is devoted to the assessment of the possibility to use a new design of a stretch die made of plastics used for fused deposition modeling (FDM) 3 D printing. Studies were conducted to assess the stress-strain state of a stretch die, from the normal pressure of a deforming sheet blank in a NASTRAN solver, using the finite element method. The convergence assessment of the simulation results was carried out for different quantities and corresponding sizes of finite elements. The optimal thicknesses of the hollow structure of the stretch die were determined by step-by-step calculations of its stress-strain state for acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG). On the basis of the conducted studies, a general algorithm was developed for the structural design of stretch dies made of plastics used for fused deposition modeling (FDM) printing.
