![]() Choose Mesh Design from the Start Page menu.But in the Slic3r manual there is a section which describes how to use FreeCAD for repairing my STL file: The silicone rubber cast is used to cast the paraboloid parts that will reflect light rays from the transmitter LED and to the receiver PhotoDiode. ![]() The wax matrix would serve to make a silicone rubber cast. So this matrix was going to be made out of wood. or it can be a 3D process (moving in the 3 dimensions at the same time).Īt first, the wax was not available for cutting a matrix.Machining can be a 2.5D process (routing the material one layer height at a time, each at different routes).There are two ways to give shapes to models in 3 dimensions in machining: While cutting serves the purpose of making 2D shapes, machining gives the piece a 3D shape. In machining, only some (not all) of the material at a centain horizontal point is vertically removed.It could take several passes to get to the bottom, but the endmill ends up milling to the bottom hence it cuts. In cutting, the mill goes to the bottom of the material on each route.Quiliro's lesson: Computer controlled machining Computer Controlled MachiningĪ Computer Numerically Controlled (CNC) router behaves differently with computer controlled cutting in contrast with computer controlled machining.
