In 3D printing, various additive techniques work by curing liquid polymers one layer at a time to form a solid object. In the industry, resin printing is also known as VAT polymerization printing or stereolithography. There are high-quality printers such as the LCD-002R resin 3d printer that you can use correctly with this technique. In 3D printing, photopolymerization happens to a liquid material, changing its fluid properties when exposed to UV or laser light. These different liquids used in 3D printing are called light-activated resins, or photopolymers. Let’s focus on the advantages of resin-based 3D printing.
Distinct characteristics of resin-based 3D printing
- All the materials used are kept in resin tanks/baths.
- The photopolymers rely on UV or daylight for activation
- Objects in resin-based 3D printing are created using photopolymerization principles
- In resin-based 3D printing, a machine generates code from digital models that have been uploaded into the system.
- Solidifying is the specific photopolymerization reaction implemented in 3D printing.
How resin 3D printing works
First, a resin tank is filled with suitable resin material, and this is done either automatically or manually. But note, skin contact should be avoided during manual filling by a specialist. Afterward, the 3D printing machine lowers the build platform and lifts it to establish a thin resin layer in contact with the build plate. During the procedure, a light source creates a pattern in the form of a single layer inside the resin, and this forces it to solidify. As the machine platform moves, this permits the non-solid resin to pass through and create a new layer residing above the build plate.
Advantages of resin 3D printing
- Resin 3D printing using devices like the LCD-002R resin 3d printer involves higher resolution, which results in better-looking finishes containing finely detailed models. In addition to this, resin-based prints possess smooth finishes that are not easy to achieve using FDM printing.
- Resin-based 3D printing is faster since it involves no filament. Instead, the machine reorients to point the laser to the resin at pre-defined locations.
- The products developed through 3D resin printing are generally more durable compared to products of FDM printing. Resin-based printing also involves curing, which means that the adhesion between layers is stronger. This ultimately creates more uniformity across all the angles and axes. In addition to this, resin 3D printing are generally preferred for creating functional engineering parts.
How objects are formed in 3D resin printing
In practice, 3D printers are capable of creating objects upside down or right side up. It all depends on the positioning of parts inside the 3D resin printer. The product output also depends on the drop or lift of the build platform on a printer like the LCD-002R resin 3d printer. For most 3D printer artists, upside-down orientation is widely available on desktop machines since it is easier to fabricate without compromising on quality. What matters the most in 3D resin printing is the supporting structures and print adhesion.
As far as manufacturing technologies go, 3D resin printing is a shining example of additive techniques used to form solid objects by curing liquid photopolymers layer by layer. Quality 3D resin printers such as the LCD-002R resin 3d printer are the best option for quality products.
