How many kinds of UV 3D printers we could find?

3D Printing

In the former, we used to introduce sufficiently the most common 3D printing technology, FDM printing. There is another common type of 3D printer we always see: LCD, SLA, and so on. What are these 3D printers?

 

SLA, LCD, DLP, and POLYJET are the 4 usual classifications of UV(Ultraviolet) 3D printers. Different from FDM, which heats the linear filament until melting and squeeze it through the nozzles. UV 3D printing technology applies a light source to the liquid printing material. Due to the different light sources and modeling methods, UV 3D printers are subdivided into SLA, LCD/DLP, and PLOYJET

 

Theories of SLA, LCD/DLP, and POLYJET

 

SLA

Apply laser point on the printing material from points to a flat. After recycling this process and getting a final 3D product.

 

LCD/DLP

Apply digital light flat on the printing material. After recycling, get a final 3D product. 

 

POLYJET

Spray photosensitive resin layer by layer on the printing plate and irradiate ultraviolet light instantly on each layer to solidification 

 

Advantages of SLA, LCD/DLP, and POLYJET

 

For SLA and LCD/DLP 3D printers, the most outstanding point is their printing accuracy and smooth surface. Despite FDM 3D printers, SLA and LCD/DLP occupy the majority of the consumer 3D printing marketing share . Sometimes these three types of 3D printers are used in dental institutions for medical treatment. Most consumers, apply this 3D printer as a daily life decoration and garage kit DIY. The picture below shows the LCD 3D printer, Foto 8.9’s artwork, and the Nergigante from Monster Hunter: World.

For the POLYJET 3D printers, the unignorable point is: it could print different material at the same time and apply it to a single model. The most basic printers can only use one resin at a time, but more sophisticated printers can combine multiple resins during the printing process, providing great flexibility in creating a unique look for parts, and even providing independent material qualities for different areas of the same part.
 


The shortcoming of SLA, LCD/DLP, and POLYJET


After advantages, the drawbacks are a significant part as well, for the consumer to choose the proper resin printer in their personal studio. The common weakness of UV 3D printers is producing exhaust fumes. It is also an urgent problem to solve for UV 3ZD printers: eliminate the polluted air at the minimum. 

 

The shortcoming of LCD/DLP:
·    the application scenario is limited. Mostly in garage kit processing.
·    To test the model’s appearance is the first goal. Need repeated printing to perfect. 
·    Could cause deformation in large size printing. 
·    High requirement in post-process
·    

The shortcoming of SLA:
·    The printing size is limit in small to medium. Such as dental, jewelry, and small-size garage kit. 

 

The shortcoming of POLYJET:
·    Printing material loss in alternate the printing material is more than other UV 3D printers
·    The service time of the nozzle is short and prohibitive in nozzle replacement.
·    The mechanical capacity is lower than others.
