3D Printing vs. CNC Machining of Plastic Parts

3D PRINTING vs. CNC MACHINING of PLASTIC PARTS
By Dean West
 
The process of 3D Printing, also known as additive manufacturing, has now been developed for several materials including plastic and metal. This article will focus on 3D printing compared to CNC machining of plastic parts.
The 3D Printing process is an additive process during which layers of molten plastic are added until the part is completely formed.  These layers can often be noticed,…

ABS: Acrylonitrile Butadiene Styrene

ABS: Acrylonitrile Butadiene Styrene
Acrylonitrile butadiene styrene (ABS) is a plastic that is a terpolymer, a polymer consisting of three different monomers. ABS is made by polymerizing styrene and acrylonitrile in the presence of polybutadiene.  Acrylonitrile is a synthetic monomer made up of propylene and ammonia while butadiene is a petroleum hydrocarbon, and the styrene monomer is made by the dehydrogeneration of ethyl benzene. Dehydrogenation is a chemical reaction that involves the removal of hydrogen from an organic molecule and is the reverse of hydrogenation.…

History of the Screw

The screw is one of the six classical simple machines.1 It is a mechanism that changes rotational motion to linear motion and rotational force or torque to a linear force.  If looked at geometrically, a screw can be regarded as a narrow incline plane wrapped around a cylinder. The screw is one of the most common simple machines and consists of a cylindrical shaft with helical grooves or ridges around the outside called threads.  …
