This research project is done by Denzel Vonk and will focus on the making of 3d printed models for composite mold production. The goal is to reliably print 3d models that are dimension accurate and capable of withstanding the making of the mold. In this project I will also be looking at the way of milling the material so I get a smooth surface finish. The first thing I will look at is the material that I will be using to print after that the shrinkage is next. To know how big the model needs to be printed, the shrinkage is important. When the model is the right size it need to be milled. It’s a amorphous material so the milling process Is a bit different than that of steel. The model will then be taken to Nedcam where we can make a mold form it. After the model is used it needs to be recycled and then used again for mold production.
To print such big models the use of pellets is very useful. They are cheaper and can be used in higher quantity’s without changing a roll unlike filament. To print with pellets your 3d printer needs to be a bit different. I will also make a concept of a 3d pellets printer in this project. When the concept is working it can be scaled up to a big 3d printer that can print big models.
