S.A.M. Spring Aided Machining (CNC with solvent) is a school project designed by three architecture students at CCA, San Francisco: Matt Boeddiker, Abelino Robles, and Tim Henshaw-Plath. (www.cca.edu) The machine is capable of rapidly prototyping and creating subtractive formwork that can be used to cast material. The machine was designed with the instruction of Jason Kelly Johnson, and Michael Shiloh in the Creative Architecture Machine class Fall 2013. Tecnically this is a transformative process where by material mass is maintained while volume is reduced ie a global increase in density.

Step 1: ASSEMBLE BODY

First step is to laser cut 1/4 inch acrylic frame. This should include a rigid stable truss to span width of desired length. Our width is two feet and height is about five feet.
Second step is to build basic 1/2 inch plywood frame as foundation for acrylic frame.
Third step is to attach 3/8 inch threaded rod through plywood foundation and connect to acrylic frame using laser cut acrylic pieces or simple zip ties.

Step 2: CREATE SPRING

Picture of CREATE SPRING
Model a 3D spring that can be printed with PLA.
Make sure that you design a central hole that is wide enough to allow a tube that caries adhesive remover liquid to pass through.
The spring should have 4 small holes that form a square shape, north, east, and south that are used to allow threaded wire to connect spring to motor.
If access to a 3D printer is difficult, a file can be sent to the online ordering company Shapeways to print your spring. (www.shapeways.com)

What are you making with this machine ??
we are dissolving foam in a process that is neither subtractive nor additive more transformative. In doing so we are creating form work with complex surface area and because the dissolving process continues for 48 hrs the form work is self releasing. In addition we are affecting the R value (or resistance to thermal conductivity) of the insulation opening the door to aestheticizing insulation a material that essential to all buildings and is never celebrated... The 3d printed spring is a second branch of research on this project in that this mechanism allows or increased degrees of freedom with a reduced cost increase only an increase in complexity of control software.
