    Absolutely amazing, another fantastic use for 3D printers.

    I like how many patterns can be printed at once. Ideal for batch manufacture.

    I worked SLA machine that makes any wax parts, layer by layer. In this machine technique is like the SLA technique but connection between layers makes by the glue spraying or sand welding.

    Neato. An original use for sand!

    A print head applies binder where the model is to be produced, whereby the binder infiltrates the most recently applied layer and connects it with the
    layer below. So we are not using a laser.

    Good Job, really complex, what material that cores?Wax?

      Hi there,
      the cores were printed in standardized silica sand and furan resin. Basically traditional and foundry proven materials. We also offer other resins, such as phenolic resin.

    How does 3d printer work to make core ?

      It's binder jetting, it use a binder on a sand layer.

    Can reused that mold
    Or only for 1 time use..

      Hi there,
      these molds and cores are printed and utilized as lost mold. So for single casting only.

    Für die innovative Firma voxeljet technology GmbH hat unsere Übersetzungsagentur auch schon Übersetzungen geliefert. Vielleicht besteht bei Gelegenheit mal wieder Bedarf.

    These germans in engineering make me sick - can't they just leave one area where they don't excel.

    Seems like it would be easier to carve this out of a billet rather than printing a mold, cleaning it, shipping it, casting it, sanding it, x-raying it, etc.

      there is no way to machine that from a single piece, no tool can get in those shapes and reach the inner sections
