What is resin 3D printing?
Resin 3D printing is a technology that allows you to create solid objects layer by layer using photosensitive liquid resins that harden under ultraviolet light. Unlike FDM (which melts plastic filament) and SLS (which fuses powder), resin 3D printing stands out for its precision and smooth finishes.
| Technology | Light source | Key advantage | Real image |
|---|---|---|---|
| SLA | UV laser | Maximum resolution |  |
| DLP | Projector | Speed |  |
| LCD | LCD screen | Accessibility |  |
These technologies make it possible to print miniatures, jewelry, functional prototypes, dental parts, and automotive components with an incredible level of detail. For example, a dental part made from resin shows smooth edges and millimeter-precise accuracy, ideal for both professional and hobby applications.
According to Protolabs, SLA is the preferred option for parts with intricate details and miniatures. In 2025, the trend points to the rise of resin 3D printing thanks to the demand for premium finishes and the emergence of safer and more eco-friendly resins.

Do keep in mind that resin 3D printing requires specific equipment, adequate ventilation, and slightly more space than a domestic FDM 3D printer. However, the professional results and versatility more than make up for the initial investment.
Types of resin and how to choose the ideal one in 2025
Have you ever wondered which is the best resin for your resin 3D printing project? Today there are options for every taste and need, from standard resin for rapid prototypes to flexible resins for parts that require a degree of elasticity. ABS-like resins also stand out, perfect if you are looking for strength similar to industrial plastic.
Water-washable resins are a trending choice in 2025, ideal for those who prioritize easy cleaning and lower toxicity. If you would like to explore further, take a look at this water-washable resin collection and discover why so many users prefer them for home printing.
| Resin Type | Popular Brand | Real Image | Main Advantage |
|---|---|---|---|
| Standard | Anycubic |  |
Easy to use and affordable |
| ABS-like | Elegoo |  |
Resistance and toughness |
| Washable | Anycubic |  |
Easy cleaning |
| Flexible | Elegoo |  |
Elasticity |
Don't forget the new eco-friendly and ultra-resistant resins, which are gaining ground for their low environmental impact and fast curing. An interesting fact: the use of eco and water-washable resins grew by 40% among home users this year.
Quick tips: store your 3D printing resins in cool places away from light, always wear gloves and shake well before use. Avoid common mistakes like mixing incompatible brands or leaving the bottle open for too long.
Unsure between water-washable resin and standard resin? Choose the water-washable resin if you want easy cleaning and fewer odors, the standard resin if you prioritize variety of colors and finishes.
Step-by-step guide to 3D printing with resin
Ready to turn your ideas into reality? Here is an easy, visual guide to achieving perfect 3D printing results with resin, from design to finished piece.
1. Model and file preparation
🖥️ Start by selecting or designing your 3D model in software such as Blender or Fusion 360. Export the file in STL or OBJ format.
Use a slicer compatible with your 3D printer, for example Lychee or Chitubox. Adjust the orientation and add support where the model requires it.
- Place support on overhanging areas.
- Orient the model to minimize marks.
- Preview how it will look before printing.
A well-prepared model is key to success in resin 3D printing!
2. 3D printer and resin settings
🧴 Clean the print bed and make sure it is properly leveled. Fill the tank with the appropriate resin, following the manufacturer's recommendations.
Adjust the settings in the 3D printer menu:
- Layer height according to the desired level of detail.
- Exposure time according to the resin.
- Controlled ambient temperature.
Always verify compatibility between resin and machine. Poor settings can ruin the job.
3. Printing process
🚦 Start printing and watch the first layers, as this is where most problems in resin 3D printing tend to arise.
Tips to avoid failures:
- Watch for bubbles in the resin.
- Ensure good adhesion to the print bed.
- Maintain good ventilation and wear gloves and a mask.
Interesting fact: reducing errors in the first layer can increase success by 80%. Don't lose sight of this step!
4. Removing and washing the piece
🧼 When printing is complete, carefully remove the platform. Take the piece off using a plastic spatula.
Wash it in isopropyl alcohol or with a Wash & Cure machine to remove resin residue. Dry it before curing.
For professional and safe cleaning, you can check out these recommended post-processing and cleaning accessories.
All done! Your piece is ready for post-processing and the final finish.
Professional post-processing and finishing of pieces
The time has come to transform your resin 3D printing creations into true works of art! 😍 Post-processing is key to making your pieces strong, smooth, and ready to shine.
The first step after printing is UV curing. Use a UV lamp or curing station to harden the resin, achieving maximum strength and a professional finish. If you don't have the equipment, you can also cure in sunlight, although the result is less uniform and takes longer.
To remove supports, do so carefully using precision pliers. This way you avoid damaging fine details. Afterwards, clean the piece with isopropyl alcohol or a Wash & Cure machine, which speeds up the entire process and protects your health.
Now comes the most creative part: the finish. Sand gently with fine-grit sandpaper to eliminate imperfections. Apply spray primer to prepare the surface and varnish to seal and add shine. According to community surveys, 70% of users noticeably improve their results by applying primer and varnish. Here you can explore Tips for professional finishes and discover recommended paints, brushes, and sprays for resin 3D printing.
Key tips:
- Cure every corner thoroughly — no rushing!
- Sand wet to avoid scratches.
- Always wear a mask and gloves.
- Try different painting techniques to personalise your piece.
With these steps, your resin 3D printing models will stand out for their quality and realism. Dare to experiment and share your results with the community!
