What is DFM?
According to Google, DFM means "design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering art of designing products in such a way that they are easy to manufacture.
The machines that were used for this project were the VersaLaser 4.60, the Makerbot Replicator, and the Roland-SRM-20.
Subtractive manufacturing is a process by which 3D objects are constructed by successively cutting material away from a solid block of material. Subtractive manufacturing can be done by manually cutting the material. (Staff 2017)
The same article states, "similar to the other prototype development technology, FDM (3D printing), CNC relies on digital instructions from a Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) file like Solidworks 3D. The CNC machine interprets the design as instructions for cutting prototype parts. The ability to program computer devices to control machine tools rapidly advances shop productivity by automating the highly technical and labor intensive processes. Automated cuts improve both the speed and the accuracy with which prototype parts can be created - especially when the material is critical (Staff 2017).”
The SRM-20 machine was used to create a South Korean boy band logo (BTS aka Bangtan Boys)
"Additive manufacturing is an appropriate name to describe the technologies that build 3D objects by adding layer-upon-layer of material, whether the material is plastic, metal, concrete or one day…..human tissue." ("AM Basics | Additive Manufacturing (AM)")
The 3D printing process includes the inputting of a filament into the machine, finding the finished file on the connected computer, starting the machine, waiting for it to heat up the filament, the watch it work its magic.
The Makerbot Replicator was used to 3D print a heart with Korean characters on it
