Week Three: CNC Milling, Vacuum Forming, Material Exploration, Workshop Network

Hi All, 

This week we have another busy schedule ... lots of exciting things to see and try. Below are some videos for inspiration and to get you thinking about how you might use the techniques introduced in the Design Lab. 

CNC Milling: Richard 

In contrast to 3d Printing CNC Milling is a more traditional subtractive process. CNC Milling is a development of traditional milling processes that have been around for over 200 years. CNC stands for Computer Numerically Controlled which means that the machine is controlled by software which gives a level of control/manipulation that exceeds what traditional Mill operators are able to do through hand-eye coordination. You can see that clearly in the clip below.



Vacuum Forming: Gabe

In vacuum forming a thin sheet of plastic is heated up until it becomes pliable. It is then draped over a form and vacuum is applied to suck the plastic towards the contours of the form until it is a precise fit. The wikipedia has a good explanation including typical uses and problems to avoid; here.



Material Exploration: Daniel

Daniel will use models and prototypes found around the Design Lab to illustrate a range of approaches in the application/exploration of materials. He'll show you where you can get free materials and go over whats available in the Design Lab shop. The materials in the shop have the advantage that the Design Lab staff have confirmed that they will work with our machines and are safe; they don't give off noxious fumes for example.

Workshop Network: Nichola

Nichola will go over the "Badge" system and then take you on a tour of our growing UNSW workshop network. The Michael Crouch Innovation Centre (MCIC) and the Engineering Maker Space are on the list. You might even get to see a waterjet cutting demonstration!



Casting: Maddy (?)

Casting is a fascinating process that several of you have expressed interest in. It also works really well in combination with some of the other techniques you've been introduced to. The video below shows how 3d printed parts can be used in sand casting aluminium. We don't have a high temperature furnace to melt metal, but the technique is very similar for creating latex moulds and casting resin for example.



See you in the Design Lab.
