Resin 3D Printing (SLA / DLP / LCD)
Resin 3D printing is one of the most popular and advanced 3D printing technologies in the world. It is used in applications that require excellent detail, smooth surfaces, and high precision.
What is SLA 3D Printing?
SLA technology uses a UV laser to polymerize photosensitive resin, building the object layer by layer with precision.
Advantages:
High resolution up to 25 microns
Smooth and clean surfaces
Ideal for detailed models and molds
Accuracy in geometrically complex structures
What is DLP & LCD Printing?
DLP relies on a digital projector that projects the entire surface of one layer at a time, while LCD (or MSLA) uses an LCD screen with UV LED lighting to cure each layer simultaneously.
Advantages:
- Faster printing compared to SLA
- Ideal for small batch production
- Fewer moving parts, reduced maintenance costs
Resin Types
The choice of the appropriate resin depends on the application. The main categories include:
Standard Resin
Good overall quality, ideal for models and prototypes
Flexible Resin
Flexible components and protectors
Tough Resin
For mechanical components with durability
Clear Resin
Transparent parts for optical applications
Castable Resin
Ideal for casting in jewelry and industrial prototypes
Dental Resin
Resins for dental use
Comparison of SLA with FDM
| Feature | SLA | FDM |
|---|---|---|
| Detail analysis | Very high | Moderate |
| Speed | Medium – High | High |
| Endurance of components | Average to good | High (depending on the material) |
| Production cost | Higher | Lower |
| Applications | Jewelry, Medical | Prototypes, functional |
Resin Printing Applications
3D printing with resin is ideal for:
Jewelry
Ideal technology for complex jewelry designs. Thanks to the absolute detail and the choice of castable resins, it allows the creation of components ready for casting in precious metals.
Modeling and art
Artists, sculptors and modelers use it to render sculpture-level details. It is suitable for statuettes, museum replicas, props and collectibles.
Product prototypes with a need for precision
For prototyping products that require precise geometries, smooth surfaces and functionality. Widely used in architecture, industrial design and mold making.
Medical/Dental models
Resin printing has proven to be extremely effective for producing tooth models, dentures, splints, and surgical guides, utilizing biocompatible resins with medical certification.
Figures, statues, miniatures
Thanks to its high resolution (up to 25 microns), resin printing is the ultimate choice for tabletop gaming figures, characters, and collectible sculptures, faithfully rendering every detail.
Post-processing
After printing, the object goes through a “curing” process for complete hardening. In addition, the following is performed:
Cleaning with IPA or other substances
Remove supports
Sanding, priming and painting (optional)

Frequently Asked Questions (FAQ) – SLA 3D Printing
🔹 What accuracy can SLA 3D printing achieve?
SLA technology can achieve extremely high precision, typically 25–50 microns, making it ideal for applications such as jewelry, molds, and dental models.
🔹 What is the difference between SLA, DLP and LCD 3D printing?
The main difference is the way the resin is cured:
- SLA It uses lasers and is more accurate.
- DLP uses a projector and is faster on small surfaces.
- LCD/MSLA It uses an LCD screen with UV light and is a more economical solution.
They are all based on light polymerization but differ in speed, detail and cost.
🔹 Is the object ready to use once printed?
No. After printing you need:
- cleaning (with IPA or similar cleaner),
- drying and complete hardening with UV curing,
- removing supports and possibly sanding or priming.
Post-processing is a key step in the quality of the final product.
🔹 How much does resin printing cost?
The cost of SLA printing depends on:
- the size and volume of the object,
- the resin to be used (standard, tough, castable, etc.),
- printing and post-processing time.

🔹 Which applications are ideal for SLA?
SLA 3D printing is ideal for:
Transparent components (with special resins)
Jewelry (molds for casting)
Dental applications (aligners, braces)
Miniatures & modeling
🔹 How can I send my file for printing?
You can send us your 3D file (.STL, .OBJ or .3MF) via contact form or by email. We will evaluate the construction and respond to you with a time and cost within 24 hours. Alternatively, you can book a online meeting with us so that we can guide you through your project.
🔹 What is the difference between Castable Resin and Standard Resin?
Castable Resin It is designed for casting in jewelry or metals. It burns cleanly without residue and is ideal for molds.
Standard Resin It is used for general applications and models, not for final production or casting.
🔹 Is there a possibility for mass production with SLA?
Yes. We have industrial SLA/DLP printers with parallel production capabilities. Whether you want 10, 50 or 100 pieces with precision and consistency, we can serve you with consistent quality and delivery time.
