3D Printing

3d printer

Overview

The 3D printer is not like a common inkjet printer. On a 3D printer, the object is printed with the third dimensions. A 3D model is built up of multiple layers. this makes the whole process called rapid prototyping, or 3D printing.

A common process of rapid prototyping is to layer a fine powder (plaster, bioplastic, polyurethane, polyester, epoxy, metal, etc.) in such a way to build layers. 3D Printers, print out the layer of powder on a bed and form a solid object. The design is defined by a (CAD) Computer Aided Design file.

The version of 3D printing I use and most use is fused deposition modeling (FDM) is another method in which molten polymer is injected on to a  support layer (raft) and the model is built layer by layer.

Another way is to use liquids, such as a photopolymer, this is also printed layer by layer.

Following, an ultraviolet light is used to activate the photopolymer liquid that makes liquid layer become a solid layer. This process is also well-known as stereolithography.

The 3D printing process starts from a number of projects from MIT in 2000 but has progressed extensively over the last few years. This is an extension of the rapid prototyping process where the basic concern was to cut the time prototyping a model to make.

The first practical application was in production from a metallic material.

Printer Size

The resolution of the current printers is among the 328 x 328 x 606 DPI (XYZ) at 656 x 656 x 800 DPI (XYZ) in ultra-HD resolution. The accuracy is 0.010 mm – 0.05 mm per inch. The model size is up to 737 mm x 1257 mm x 1504 mm.

Usage

Nowadays, a 3D printer is mainly used in business enterprises and concepts which demand time-saving. These include medicine, architecture but also the entertainment industry such as game and film industry. Even artists use a 3D printer for their creations in a comparatively short time in a solid shape to print.

Companies

Today there are more and more companies that specialize in the printing of 3D models and supply services for business and individuals. Make My Ideas use Shapeways as a means to sell our designs.

Conclusion

3D printing still has its disadvantages for the hobby home user they are still the high cost of a 3D printer. Another disadvantage is that it takes hours or even days to print a 3D model (depending on the difficulty and design of the model). Excluding the above, the professional 3D software and 3D model design is also in a high-cost range.

Alternatively, there are already simplified 3D printers for hobbyist which are much cheaper. And the materials it uses is also less expensive. These 3D printers for home use are not as accurate as a commercial 3D printer.

But can be modified to be a lot more accurate and less time-consuming follow are guides.
