Do you have a business where it would be practical to have a 3D printer? For such cases, the best choice is affordable but still high-quality DLP 3D printers that work by solidifying liquid resin in layers using light. In addition to professional 3D printers, FDM 3D printers, and spare parts for printers, you can also find resin 3D printers. If you do not know which one to choose, please don't hesitate to contact us and we will prepare some options for you.

What is a Resin 3D printer and how does it work?

The most common 3D resin printing techniques are stereolithography (SLA) and digital light processing (DLP). Resin 3D printers are popular for making high-precision models, isotropic and waterproof prototypes, and also individual parts from advanced materials with fine properties and sophisticated surface treatment. Such technologies used to be demanding and costly, but today they are available with smaller 3D printers, at an affordable price, and with unparalleled versatility in the use of different materials. Both printing technologies work by selectively exposing liquid material to a light source - an SLA laser beam and a DLP projector - to form a thin and solid layer that creates a 3D model. Although the two printing technologies are very similar, each has its own specific characteristics. DLP 3D printers are built around resin with a transparent bottom and a construction platform that drops into the resin container and creates upside-down, layer-by-layer parts. Such printers use a digital projector screen for printing, so the image of each layer consists of square pixels, which results in a three-dimensional layer formed of small rectangular cubes or voxlov.

What are the benefits of Resin 3D printers?

First of all, resin 3D printers are more affordable compared to 3D professional printers. Because they use light to solidify liquid resin in layers, resin 3D printers are extremely accurate and suitable for making high-precision models. 3D printers (SLA or DLP) also offers one of the highest Z-dimensional accuracy, and the height of each layer can be adjusted, giving designers the perfect balance between detail and print speed. In terms of print speed, resin 3D printers are comparable or even faster when printing smaller models, and DLP 3D printers are even faster when printing larger models. Of course, the speed also depends on the capacity of the printer and the materials. One of the key advantages of resin 3D printers is also the possibility of a wide selection of materials from which 3D models can be printed. Unlike other 3D printers that melt materials, resin 3D printers dry and solidify the liquid resin, which means they have no temperature limits like when printing FDM filaments. However, due to the smell, they must be in a well-ventilated area at all times. Unlike FDM printers, they also take up much less desktop space.

What are resin 3D printers suitable for?

Due to their exceptional accuracy, print speed, and finished product quality, DLP 3D printers are suitable for printing smaller, highly accurate printed products and for printing molds such as miniature objects or figures with many details, jewelry models, dental prostheses, crowns and bridges, figures for making 3D animations…
