Product manufacturing method producing patterns for immediate use or for positive or negative patterns for production of further heating plastic coated particles

摘要

The product comprising bonded particles is subsequently pressed under hot isostatic conditions to evaporate the plastic and compress the product, the shrinkage being calculated beforehand, to ensure that the final product is the correct size after releasing the pressure. Preferred Features: Coated particles may be heated in layers by a laser beam. The final compressed product can be used as a mold or former for producing other items. Particles may have cores of different materials.
