Concrete Coasters
Various nerd coasters.  They start life in Adobe Illustrator before they are imported into CamBam and cut out of MDF on the CNC.  A quick sanding job and the “masters” are ready to be coated with a mixture of silicone caulking and corn starch.  After 2 hours the silicone is cured and the mold is ready – spray the mold with release agent, pour in your concrete (or resin), wait a bit and then success, a coaster is born!coasters5 coasters4 coasters3 coasters2 coasters1 coasters
