What is resin 3D printing?
Resin 3D printing is a technology that builds solid objects layer by layer using photosensitive liquid resins that cure under ultraviolet light. Unlike FDM (which melts plastic filament) and SLS (which fuses powder), resin 3D printing stands out for its precision and smooth surface finish.
| Technology | Light Source | Key Advantage | Real Image |
|---|---|---|---|
| SLA | UV Laser | Maximum resolution |  |
| DLP | Projector | Speed |  |
| LCD | LCD Screen | Affordability |  |
These technologies make it possible to print miniatures, jewelry, functional prototypes, dental parts, and automotive components with an extraordinary level of detail. For example, a dental piece made with resin displays smooth edges and millimeter-level precision, making it ideal for both professional and hobby applications.
According to Protolabs, SLA is the top choice for parts with intricate details and miniatures. In 2025, resin 3D printing continues to grow in popularity thanks to increasing demand for premium finishes and the arrival of safer, more eco-friendly resins.
Want to dive deeper into materials and explore what's available? Check out the resin types for 3D printing and find the perfect one for your projects.
Keep in mind that resin 3D printing does require specific equipment, proper ventilation, and a bit more space than a standard FDM printer. That said, the professional results and versatility more than justify the initial investment.
Types of resin and how to choose the right one in 2025
Wondering which resin is best for your 3D printing project? There are now options to suit every need and application, from standard resins for quick prototyping to flexible resins for parts that require some give. ABS-like resins are also a standout choice if you need strength comparable to industrial plastic.
Water-washable resins are a major trend in 2025, perfect for anyone who prioritizes easy cleanup and lower toxicity. If you'd like to explore further, take a look at this collection of water-washable resins and see why so many users prefer them for home printing.
| Resin Type | Popular Brand | Real Image | Main Advantage |
|---|---|---|---|
| Standard | Anycubic |  |
Easy to use and budget-friendly |
| ABS-like | Elegoo |  |
Strength and toughness |
| Water Washable | Anycubic |  |
Easy cleanup |
| Flexible | Elegoo |  |
Elasticity |
Don't overlook the latest eco-friendly and ultra-durable resins, which are gaining popularity for their low environmental impact and fast cure times. An interesting fact: the use of eco and water washable resins grew by 40% among home users this year.
Quick tips: store your 3D resin printing supplies in a cool place 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.
Can't decide between water washable and standard resin? Go with water washable if you want easy cleanup and less odour, or choose standard if you prioritise a wider range of colours and finishes.
Step-by-step guide to resin 3D printing
Ready to bring your ideas to life? Here's a simple, visual guide to achieving perfect resin 3D prints, from design all the way to finished part.
1. Model preparation and file setup
🖥️ 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 printer, such as Lychee or Chitubox. Adjust the orientation and add supports wherever the model requires them.
- Place supports on overhanging areas.
- Orient the model to minimise surface marks.
- Preview the result before sending it to print.
A well-prepared model is the key to successful resin 3D printing!
2. Printer and resin setup
🧴 Clean the build plate and make sure it is properly levelled. Fill the vat with the appropriate resin, following the manufacturer's recommendations.
Adjust the settings in the printer menu:
- Layer height based on the level of detail required.
- Exposure times suited to your resin.
- Controlled ambient temperature.
Always check compatibility between the resin and your machine. Incorrect settings can ruin your print.
3. The printing process
🚦 Start the print and keep a close eye on the first few layers, as this is where most resin 3D printing issues tend to occur.
Tips to avoid print failures:
- Watch out for bubbles in the resin.
- Ensure good adhesion to the build plate.
- Keep the area well ventilated and always wear gloves and a mask.
Interesting fact: getting those first layers right can increase your success rate by up to 80%. Don't take your eyes off this step!
4. Part removal and cleaning
🧼 Once the print is complete, carefully remove the build platform. Detach the part using a plastic scraper.
Wash it in isopropyl alcohol or use a Wash & Cure machine to remove any residual resin. Make sure it is fully dry before curing.
For professional and safe cleaning, check out these recommended post-processing and cleaning accessories.
That's it! Your print is ready for post-processing and finishing.
Professional post-processing and finishing for resin prints
Now comes the fun part — turning your resin 3D prints into true works of art! 😍 Post-processing is what makes your pieces strong, smooth, and ready to show off.
The first step after printing is UV curing. Use a UV lamp or curing station to fully harden the resin, maximizing strength and achieving a professional finish. No curing station? You can cure in sunlight, though the results are less consistent and take longer.
When removing supports, take your time and use precision pliers to avoid damaging fine details. Then clean your print with isopropyl alcohol or a Wash & Cure machine, which speeds up the whole process and keeps you safe.
Now for the most creative part: finishing. Sand gently with fine-grit sandpaper to remove any imperfections. Apply a spray primer to prep the surface, then a varnish to seal and add shine. According to community surveys, 70% of users see a significant improvement in their results when using primer and varnish. Explore professional finishing tips and discover recommended paints, brushes, and sprays for resin 3D printing.
Key tips:
- Cure every corner thoroughly — don't rush!
- Wet sand to avoid scratches.
- Always wear a mask and gloves.
- Experiment with different painting techniques to personalise your print.
Follow these steps and your resin 3D prints will stand out for their quality and realism. Don't be afraid to experiment — and share your results with the community!
