1. Model Makers

2. Model Maker (MM) is a commercial rapid prototyping (RP) system using tiny jets to deposit materials onto a platform to build physical models. Also, a cutter is employed to plane off the deposited surface in order to maintain smaller layer thickness and hence, model accuracy.

3. History of MM
(MM) was developed by Sanders Prototype INC. in the early 1990’s
Wanted to revolutionize the RP industry in accuracy

4. Original Model Maker Materials
Build Material
−Wax based thermoplastics
Support Material
−Wax based material with very low
melting points

5. Modern Materials for MM
Metallic compounds
Thermoplastic compounds

6. MM Process
MM system builds up layers of materials using the method of melting and fusing
Uses a solid modeler , inkjet print heads , and high precision milling techniques

9. MM Materials
Below is a 4-inch model made by the Extrude Hone "ProMetal“ process.  Made of stainless steel powder which is infiltrated with bronze to braze it together, it should be quite long lasting.
