What you should pay attention to when choosing a 3D printer for the implementation of your projects.

  1. The size of the working chamber, the diameter of the nozzle and the height of the print layer.
  2. Materials used.
  3. Printing technology.

Working chamber size.

Pay attention to the size of the working area. The large area of ​​the 3D printer not only allows you to produce large-sized parts without the need to break the model into components, but also launch many small parts in one "sitting". This reduces the makeready ratio and directly affects the cost of manufacturing products. However, in the case of FDM technology, it is worth paying attention to which nozzles a particular machine prints. The nozzle directly affects performance. The larger the nozzle, the more material is squeezed out per unit of time by the extruder, which makes it possible to print with a higher layer height. The print time of the product is shortened and the quality of workmanship is reduced. It is worth choosing between cost and quality. In the case of 3D printing with photopolymers, in addition to the size of the camera, it is worth paying attention to the layer height. The lower the layer height, the less shagreen on the surface of the product. The difference in cost when changing the layer height is calculated in the same way as FDM.

Materials used.

As a rule, the choice of material most often already determines the choice of a 3D printer. However, there are 3D printers that allow you to print products from various materials. In this case, you should pay attention to the presence of a closed case for a 3D printer. It will be a critical factor in the accuracy of highly shrinkable materials. In addition to the above, it is worth paying attention to the possibility of printing with two materials. This fact will allow not only printing with two nozzles, but also printing a supporting material from a soluble material. Such printing is one of the most expensive in terms of material cost, but the best in terms of surface quality over the supporting material.

Printing technology.

XNUMXD printing technology is usually determined by the choice of material. In different technologies, print quality is characterized by different parameters. In order to understand in detail, you will have to delve into the details. You can read more about accuracy in the article: ACTUAL PRODUCT SIZE AFTER 3D PRINTING.
