Design Engineering





Working with Alchemy Models is refreshing. We can work with any input that you might have, from 2D AutoCAD files to 3D SketchUp! files. These files are converted to 3D solid models that are suitable for 3D printing. Before the model is actually built, however, the client will have a series of renderings to approve. If there are changes, they are made, and new renderings submitted. This insures that the conversion process was accurate, and that the final model is correct.
What is 3D printing? 3D printing is very similar to the 2D printing that we're all familiar with at home. When we print a document, the laser or inkjet printer slides a piece of paper in, and prints the document, back and forth, from top to bottom, until it is done. With 3D printing, the same process occurs, except that this process is repeated about 250 times for each vertical inch of a model. Instead of paper, the process uses a proprietary, high performace plaster-based powder. Instead of ink, we use a high tech binder that reacts with the powder.

Here's the process.

1. A model is loaded for print.

2. The operator kicks off the job.
3. The print software slices the model from bottom to top (.004" per slice).

4. A slice is sent to the printer.
5. The printer spreads a thin layer of powder over the build area.

6. Print heads travel back and forth over the area, printing the layer.

7. A new slice is sent to the printer.
8. The process repeats until the job is complete.

Once the 3D print process is complete, the model is removed from the machine, and finished to order.
