If you mix concrete or plaster to go into your mold, you may store it temporarily in the CNC lab, under the Precix. It must have cardboard underneath it, so that no concrete or plaster spills onto the tile floor.
All,
The below is a link to anchoring cement. It has no aggregate, and has more strength than concrete if you were looking to test your blocks that you make:

Another option is to use plaster. Do not forget to add draft angles to your molds so that the block will come out!!!
For the next phase I decided to experiment using the CNC Mill.
Using double sided tape to secure the foam to the platform.

Initial cuts on the foam
Because this particular piece of foam measured 15×15 I had to scale down my patterns to 7 5/8″. To save time and material, we programmed the CNC mill to block out the portion with no pattern
one hour and fifteen minutes later!
Very happy with the end results of this pattern.
My second pattern is also successful with this one I played around with the elevations of the rings.
Pattern #3 wasn’t as successful as the others. I’m not sure what exactly went wrong, or what was over looked prior to beginning.
Not happy with the initials result of this pattern I went through my art supplies and found a drill bit.
I used it to carve out the excess foam I didn’t want
Although manually carving the foam is not as neat and clean like the CNC mill I’m much happier with this end result.
holding my patterns up against my lamp. I really like the transparency
Fresh out the laser cutter. This second pattern is more like overlapping rings. It Also reminds me on a dream catcher.
created this cute using 4×4 pattern
This third pattern reminds me of a spider web.

Since you all are starting to look at joinery, I wanted to post the following so you all can think about CNC joints. There are also examples of some of these joints in the CNC lab as well.

I began by creating three different patterns on AutoCAD.
I decided to Laser cut my patterns in three different sizes 16×16, 8X8 and 4×4 (inches)
I played around with the patterns
This organic Pattern is my personal favorite. This cube was made using the 8×8 patterns
I used the same pattern in 16×16 to create this lamp like object.
All,
Please use the below to understand how to use the Roland CNC machines. There are both primers and tutorials to show you how to load the machine as well as set your file up in Rhinocam.
The link below is a short document that we would like you to fill out each time you try an iteration. This is meant to help others when they look at your projects to see where and how the failures happened in your process.
