These two main plastic, you can not 3d print out to do the original form!

Two compared to 3d printing out East Rail Line Extension more suitable CNC lathe raw materials are polypropylene and paraformaldehyde (alias acetal). Make us explore such issues one by one:

Up to now, no key rapid property management software prototyping technology companies give PP as a raw material for 3D printing out. The only way to prototype it is to apply CNC lathes. There are some SLA and Polyjet raw materials that claim to be "similar to PP", but there are limitations to the similarity of raw material properties. For example, the original shape of a live door hinge made in this "similar pp" material does not easily exceed multiple bending cycle times; it will easily break. Or, to prevent the original hinge from breaking, you may have to adjust the design of it. This often destroys the original intention of designing the original shape of the product, and thus, in a sense, it is insufficient. The application of CNC lathe laser cutting PP daily life door hinges is the best choice for the new technology on the market at this stage.

Acetal (polyformaldehyde, prototype plastic parts POM) transmission gear is also called acetal):
Similar to the case of polypropylene, there is not a single key rapid protoform company giving acetal as a raw material for 3D printing out. Even if you could print out with acetal, you would lose some of the important characteristics that acetal gives. For example, acetal is often applied because of the finish its surface layer has (it has a low frictional resistance). This property makes it a respectable plastic cumbersome to organize involving transmission gear or touching the surface layer. In general - and this is the condition of all 3D printed out surfaces, not only acetal - 3D printed out surfaces are not easily as polished as molded or machined components. This means that, all else being equal, the frictional resistance will expand.

In the case of acetal, this is also particularly relevant because one of the features you want is low friction. Raising some additional friction on a slippery part will make it increasingly difficult to detect the role of the part, which in turn prepares the whole process for a larger range of fabrication. Because of these reasons, CNC lathe machining is usually the better way to protoform new design solutions with acetal that must some software performance testing.

Generally speaking, the effect of 3D printing out and CNC lathe machining lies in the conclusion of the prediction (naturally, there is also the technicality of the machine equipment and raw materials that can be used). At the beginning of the development and engineering project process, the technicality of 3D printing with the application of "special polymer-like" raw materials is likely to be sufficient to complete the design optimization and rapid prototype development. In other words, if the prototype has to be tested for other kinds of software performance prior to manufacturing, then the prototype will be tested for validity on the specific material and it will be mass produced. The most cost effective and efficient way to do this is to use a CNC lathe for a small number of prototypes. If more rigorous testing must be carried out on a large number of prototypes, then small-scale taxpayer manufacturing on an injection molding machine is the next step in respecting the facts. In all such cases, innovative mechanisms are there to assist.
