Basicly there are two tipes of 3D printing technology. In the first the point is to make many micro layers from some material that gets hardened. The second is to make prints on a white plaster with the shape of the object sliced horizontal. After printing it is soaked in epoxy resin or some super glue.
These 3D printers are on everyday use but are expensive yet. The prices are between $45k-$70k. So they are worth only if you will make business from the 3D objects these days.

I want to show you some of the good models on the maket recently.

Alaris30 Desktop 3D Printer can print in exeptional detail depth with a combination of 28μ layer made of very small drop and in very high resolution of 600×600 dpi.

ZPrinter 650s is designed for the hardest commersial and educational tasks. It’s performance is said to be best in the available 3D printers.

3D printing with the VersaUV LEC-300 inkjet printer and cutter. This machine can print raised textures on mostly every material out there. Cool, despite it’s not that much 3D printer.
