Why Should You Buy a Resin 3D Printer?

For those that desire one, home 3D printers are now widely available and reasonably priced. They’ve evolved from a nerdy curiosity to practical instruments that can be used to make art, develop projects, and address minor issues around the house. A 3D printer’s applications are only limited by your creativity!

However, a whole new kind of 3D printer is already making its way into the home market. These “resin” 3D printers produce 3D items using entirely different principles from the ones you may have seen before. What is a 3D resin printer, and should you purchase one over the existing, more conventional models?

The “Cartesian” style of 3D printer is the most popular FDM device. The print head on this can accurately position the tip of the head at any XYZ coordinate within the build volume of the printer since it is positioned on adjustable rails.

What unites all FDM printers, regardless of the technology they use, is the layered filament extrusion process. In this way, resin printers are fundamentally different.

How Resin 3D Printers Work?

Resin 3D printers and FDM printers are fundamentally different from one another. First, rather than being a spool of filament, the substance is a liquid resin. A reservoir is used to store this liquid. Even though it is often turned upside down, the resin printer still utilizes a build platform for the object that is being produced. As each layer is created, the platform is raised out of the resin vat. When exposed to the proper kind of light, the resin itself cures since it is light-sensitive.

Each layer is built up using a precise light source until the complete final sculpture has been removed from the vat. Compared to FDM printing, it unquestionably seems lot more futuristic!

Resin printer types

Although the underlying idea of curing photosensitive resin with light is the same across all resin printers, how each one does it varies. 3D resin printers really come in three main sorts.

Stereolithography (SLA)

The first 3D printing method was really SLA, which has a long history in engineering, particularly in the aerospace industry. A laser and moveable mirrors are used in this kind of printer to focus a tiny point of light. Each layer may be drawn quickly since the resin will get harder wherever the UV laser is concentrated.

Aside from the upright design, which lowers the platform into the resin tank as each layer is finished, SLA printers may also feature the upside-down inverted design, which makes the model seem as if it has been dragged up out of the tank. SLA printers often provide very smooth surfaces and provide finely detailed prints.

Digitized Light Processing (DLP)

The word “DLP” may have come up previously in connection with projector technology, and that is indeed the relationship in this case. The same digital micromirror technology that DLP projectors use to display pictures is also used by DLP resin printers. Since a complete layer of resin is being cured at once, DLP printers are a bit quicker than SLA models, which can only print one spot at a time. Although big print areas may not exhibit the same level of precise and exact detail as SLA machines based on lasers, DLP resin printers are also noted for their lovely smooth surfaces.

Liquid Crystal Display (LCD)

Each layer is cured separately by these printers using a monochrome LCD display with a UV backlight. By letting light through or selectively filtering it out, the LCD display basically serves as a mask. This smart use of established and well-understood LCD technology has significantly reduced the price of resin printers. The majority of the low-cost resin printers on the market today use LCD technology.

Compared to SLA machines and DLP printers, which are prone to distortion, LCD resin printers are both quicker and more precise. The disadvantage of LCD printers is that they need more maintenance and have a shorter lifetime than the aforementioned technologies.
