Are you a 3D printing enthusiast seeking the highest level of print quality? Or could you be frustrated with poor finished 3D object surfaces?

Better still, are you looking for a technology that will guarantee you a faster printing speed? Look no further than the UV-curing 3D printing.

Stereolithography (SLA) is the earliest 3D printing technology that uses UV curing resin to create printed parts. UV 3D printing helps you achieve faster and better quality prints.

What Is UV 3D Printing Technology?

SLA printers use UV resin to create 3D printed parts. A galvanometer guides laser beams to hit the resin tank. Then the laser cures that part of the resin exposed to it.

Next, the elevator then raises the build platform by a layer. Thus, the light source cures the subsequent layer. The printer repeats the process until it completes printing the part.

Stereolithography (SLA)

What Is SLA Technology?

Stereolithography is a 3D printing technology that uses computer pre-programmed CAD software to move laser beams. The UV light source helps cure the print part exposed to it.

Industrialists predominately use SLA printers to create concept models, complex prints with intricate geometry, and rapid prototyping.

How Does An SLA Printer Work?

An SLA 3D printer uses a high-powered laser to cure or harden the liquid resin. Such resins are contained in a resin tank. The quick curing process enabled by the UV light in the build plate helps create 3D objects with desired mechanical properties.

The SLA process or the resin 3D printing converts UV curing resin into solid 3D plastics. The conversion from resin to solid shape happens in a layer-by-layer fashion through photopolymerization.

Digital Light Processing (DLP)

Digital Light Processing (DLP) is a three-dimensional printing technology that printers manufacture photopolymer 3D prints. Notably, DL P remains quite similar to the SLA but retains a significant difference.

While SLA uses a laser beam to trace a layer to harden, DLP uses a projected source to cure an entire layer at once. Also, DLP 3Dprints parts or objects layer by layer.

Best 3D Printer UV Resin

You use plastic filament in 3D printing, such as FDM printing. Likewise, you use liquid resin in resin 3D printing to create printed models.

Liquid resin is a mixture of various chemicals and additives that determine the mechanical and chemical properties of the resin.

So, just as the plastic filament quality determines 3D print quality in FDM processes, liquid resin quality fully accounts for the final object print quality in resin 3D printing.

Here is a list of some of the best three printer UV resins:

Siraya Tech Company produces the Siraya tech liquid resin. The Siraya tech brand of resin remains one of the best resins you can find for your resin 3D printing.

It smoothens out any layer lines that may appear on the printed part. Also, it is perfect for creating hallow prints. The resin allows the printed object to strengthen without turning brittle.

More importantly, it provides the advantage of printing and curing faster.

The Anycubic plant-based resin is a popular resin that has a lower odor. Additionally, it doesn’t get as thick when subjected to cooler temperatures as with standard resin.

More fundamentally, it is an affordable liquid resin good enough for most applications. It is easy to print with and offers beautiful model clarity.

It is used for producing objects with minute details. Also, it is rigid but not brittle.

Phrozen Onyx Rigid Pro 410 is a tough and durable resin with great flexibility. The flexibility enables it to achieve dimensional stability. Thus, it is suitable for drops in the tiles as they can’t easily shatter into pieces upon such drops.


What Is a UV 3D Printer?

A UV 3D printer is a printing technology that uses liquid resin and light to produce solid 3D printed parts.

How Does the UV 3D Printer Work?

It uses a UV laser light that applies the object’s shape to the surface of a photopolymer tank. The resin solidifies to form a 3D print. This process is done repeatedly until the whole 3D model is complete.

Do 3D Printers Use UV Light?

Yes! Digital Lighting Processing (DLP) 3D printers use UV light to print 3D models. The 3D model is sent to the printer using CAD software.

The printer projects the model image onto the Vat of the liquid. The liquid solidifies where the light hits, and the object is cured layer by layer, forming a 3d printed part.

What Is 3D Printing in UV Resin?

It is a 3D printing technology in which liquid resin is stored in a container. The print resin is not injected through the nozzle, as with filament3D printing.

A UV light source then hits the part of the resin exposed to it, resulting in the hardening of that layer. The process is repeated layer upon layer until the 3D model actualizes.


Resin 3D printing has improved the 3D print quality in a big way. Professionals and enthusiasts embraced it for its fast printing speed, wide range of application areas, and lower printing costs.

Significantly, you’ll find numerous resin types in the market for your resin 3D printing. The choice depends on your individual print needs.
