Things That Hold Back 3d Printing World

3D printing is the most practical and economical way of mass prototype production. But creating a 3D model is not really as easy and simple as everyone expects it to be. You don't only need to learn how to use the cad  program but you also have to learn how to design a working model. You also need to learn how to fix models by yourself to be able produce a satisfactory resoult. It really takes a lot of time and skill and trials to create a working cad model.
There are many 3D model libraries in the Internet that you can download for free. However, most of the cad models are either not moderated or incomplete and will not be able to produce satisfactory results. Moreover, you can’t really be sure that a downloaded model will work in tune with your 3D printing solution. Most 3D printing technology in the market requires a certain design technique for it to deliver good results. This is also why 9 times out of 10, a single model will not create a quality part of a different 3D printer.

Additive manufacturing or 3D Printing improved tremendously on reduction of material costs this year. But printing expenses are only a small drop in ocean of problems . Many 3D printers today are limited to material of choice which is plastic like ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid) to create products as needed. Such materials work just fine for small prototypes with no working parts. However, they are still too far weak to be employed to create working common household products. They can’t take a lot of pressure making the product to break apart completely.
3D prints are also in additional to that, different 3D printing technologies are using proprietary consumables which only works for a specific 3D printer. You still have to purchase a specific material for it to work in tune with your equipment. It is rather annoying but unfortunately, we can’t do anything about it until 3D Printing Companies decide to standardize the materials.

And lastly there many 3D printer types available in the market. Each type of printer has its own pluses and minuses. The main consumer-level 3D printers are the FDMs. These kind of 3D printers extrudes ABS or PLY plastic in a relatively safe container and the materials cools down pretty quickly to assume a shape,form or model. The print outputs are safe to touch right from a machine while leaving little mess.
That however, is not the same for many other types of 3D printers. For example, 3D printing solutions that use Resins as the main consumable can produce more detailed products. But they are much more expensive to run and they are messy. Powder-based printers are the most dangerous types and messy and is literally explosive-bomb. Another 3D printing solution either operate at high temperatures, produce horrible parts or leave an intolerable amount of unrecoverable waste.
