At present, for the shell required by the advertising luminous characters, the materials must be resistant to high temperature, tough, transparent and opaque, non-conductive, and not afraid of ultraviolet rays. There are many materials on the market that can meet these characteristics, and PLA materials specially used for melt lamination molding can also meet these characteristics. The most important thing is that under the environment of greatly improving environmental protection production in China, PLA is still made of degradable materials, which is a real environmental protection material. Combined with 3D printing technology, the current production method of advertising channel letters becomes more flexible and more in line with the market demand for creativity. Of course, in addition to PLA materials, there are many other kinds of materials used for 3D printing. Let's give you a brief introduction:

Keweide - what are the 3D printing consumables suitable for channel letters?

First: PLA
Of course, the first one to appear is the PLA mentioned by kovid at the beginning, which is polylactic acid. This consumable is probably the most widely used and widely used consumable in the whole FDM technology. The main reason why it is so good is that it is easy to print, easy to form, odorless and more environmentally friendly. However, the disadvantage is that PLA is relatively brittle and cannot be bent, twisted or repeatedly dropped, which will cause damage and fracture of the finished product.

Second: ABS
ABS is acrylonitrile butadiene styrene. As an FDM consumable, ABS has the advantage of high printing strength, and the durability and high temperature resistance of the products are higher than those of PLA. It can also be recycled and used, and its practicability is even better than that of PLA. However, when using ABS consumables, you should pay attention to the printing temperature at all times during the printing process, and pay attention to the warpage when cooling. Moreover, the printing process will emit a relatively unpleasant smell.

Third: PETG
PETG is polyethylene terephthalate glycol. This kind of consumables is second only to those commonly used by PLA and ABS. However, this kind of consumables is more widely used. For example, our common bottle containers are made of this material. PETG combines the advantages of PLA and ABS into one. It is higher in toughness than ABS. It is easier to print than ABS. It does not have warped edges, no odor and no bubbles. Although it combines the advantages of PLA and ABS, its disadvantages are obvious, such as easy moisture absorption, sometimes sticking nozzles during printing, easy wire drawing, and not suitable for supporting materials.

The above three types of printing consumables are more suitable for advertising luminous characters, while there are many other types of consumables, such as ASA, TPU, PA, etc., but these are not mainly used for advertising luminous characters. Well, the 3D printing consumables for advertising channel letters are introduced. If you need to know more about 3D printing, please click on other pages of the website.
