Buy a photopolymer 3D printer

Photopolymer 3D printers are gaining popularity due to their incredible level of detailing and fast printing capabilities. The accuracy of photopolymer printers can reach up to 10 microns. To build models, they use special photopolymer resins that harden under UV light.

Differences in Technologies for Working with Photopolymer

Despite their external similarity, photopolymer 3D printers can operate using completely different technologies for creating 3D models:

• SLA (Stereolithography Apparatus). In SLA printers, a laser is used. It selectively cures the photopolymer resin that is inside of the printer’s tank. The laser shines on the bottom of the reservoir and is directed by galvo meters to the exact area that needs to be cured. This continues until the entire layer is solidified, then the build platform raises by one layer, and the process repeats until the model is fully printed.

• DLP (Digital Light Processing). DLP printers use projector instead of ultraviolet laser like in SLA. The projector illuminates over the entire layer of resin, selectively creating the printing model using thousands of tiny mirrors known as digital micromirror devices that direct the light projection. In these projectors, pixels are used to create images, and layers consist of voxels, similar to how conventional 2D or 3D cameras work.

• LCD Stereolithography (LSL). Like DLP, LCD printing involves illuminating entire layers at once to cure the photopolymer, but without the use of mirrors. Instead, powerful liquid crystal displays emit light onto the model with the help of LEDs. The LCD panel blocks the illumination in areas that should not be polymerized. The liquid crystal screen allows light to pass only through the sections that need curing, simplifying the process and eliminating the need for mirrors or galvo meters.

Purpose of Photopolymer Printers

• Creation of high-quality, highly accurate prototypes with great detail;
• Manufacturing of master models in a branch of production;
• Creation of finished products, toys, mechanisms, etc.;
• Production of tooling models and molds for small-batch casting.

Advantages of Using a Photopolymer 3D Printer

• Enables the creation of highly accurate models of any complexity;
• The surface of finished products is extremely smooth and easy to post-process;
• A wide variety of printing materials available;
• High printing speed;
• High operational stability and minimal defect rate in finished models.

Pay Attention! The printing speed of a photopolymer printer depends on the number of layers, not on the number of models on the build platform, as it is in FDM printers.

Application Areas of Photopolymer Printers

The photopolymer printer represents the next step in the evolution of 3D printing, that is why it is widely used in the following fields:

• Medicine;
• Science;
• Jewelry industry;
• Aerospace industry;
• Mechanical engineering;
• Education, ect.
