3D printing has rapidly evolved from an experimental technology to an essential tool for industries ranging from healthcare and automotive to fashion and engineering. One of the most popular 3D printing methods, especially for those seeking high-quality prints with incredible detail, is resin 3D printing.
But with advancements in technology and changes in material costs, is resin 3D printing still worth the investment in 2025? In this article, we’ll explore the key factors that determine whether resin 3D printing is the right choice for you this year. From print quality to cost, safety to maintenance, and practical use cases, we’ll weigh the pros and cons of resin printing to give you a comprehensive guide.
What is Resin 3D Printing?
Resin 3D printing, also known as photopolymer printing, uses liquid resin that is cured layer by layer using a light source—usually UV light. The most common types of resin printers are SLA (Stereolithography), DLP (Digital Light Processing), and MSLA (Masked Stereolithography Apparatus).
These printers create high-resolution objects with smooth finishes, making them ideal for applications requiring fine details. Unlike FDM printers, which extrude plastic filament, resin printers cure each layer of liquid resin, offering exceptional precision and an ultra-smooth finish.
The Pros of Resin 3D Printing in 2025
1. Exceptional Print Quality and Detail
One of the primary reasons resin printing is still highly valued in 2025 is its superior print quality. Resin printers can achieve sub-millimeter layer resolution (typically ranging from 25 to 100 microns). This allows for intricate details that are difficult to replicate with FDM or other printing methods. If you’re creating highly detailed models, miniatures, jewelry, or dental molds, resin printing stands out as the superior option.
2. Smooth Surface Finish
Resin prints are known for their smooth and glossy surface finish. The absence of layer lines, a common issue in FDM prints, makes resin-printed objects look cleaner and more polished. In industries where aesthetics matter, such as fashion and jewelry, resin printing provides a finish that requires little post-processing, saving both time and effort.
3. Variety of Specialized Resins
By 2025, resin formulations have expanded, and there are now a wide variety of specialized resins available, each suited to different needs. These include:
- Standard resins for everyday models
- Tough resins for engineering parts
- Flexible resins for creating bendable products
- Castable resins for jewelry making and lost-wax casting
- Dental resins for medical applications
This versatility ensures that resin printing can meet the demands of a broad range of industries.
4. Precision for Complex Designs
Because resin printing can produce highly detailed prints with fine features, it’s particularly beneficial for projects requiring precision. Miniatures, prototypes, and detailed molds are prime examples of objects that benefit from the capabilities of resin printers.
The Cons of Resin 3D Printing in 2025
1. Higher Initial and Ongoing Costs
While resin printing offers unmatched quality, it comes at a higher price point than FDM printing. In 2025, entry-level resin printers can range from $200 to $500, with higher-end models exceeding $1,000. The price of resin material is also higher compared to FDM filaments, with a liter of resin typically costing between $30 to $70.
Beyond the initial purchase, resin printing often requires additional supplies such as:
- Isopropyl alcohol for cleaning prints
- Post-curing stations to harden the print further
- Specialized gloves and filters for safe handling of resin
In the long run, resin printing can be a more expensive choice than FDM, especially for users who print frequently or at larger scales.
2. Complex Post-Processing Requirements
Post-processing is a significant part of resin printing. After printing, the model must be carefully removed from the build platform and cleaned in isopropyl alcohol to remove excess resin. UV curing is then required to fully harden the print.
This extra step can be time-consuming and requires additional equipment such as a UV curing station or a dedicated curing chamber. For users looking for a more streamlined experience, this post-processing phase can feel like a burden.
3. Health and Safety Concerns
Resin materials, especially in their raw form, are toxic and require proper handling. Users need to wear gloves and masks to protect themselves from resin exposure, and the workspace must be well-ventilated. Fumes emitted during printing and curing can be harmful, especially in poorly ventilated areas.
While some resins in 2025 are marketed as low-odor or biocompatible, the safety measures required for handling resin still make it less user-friendly compared to FDM printing.
4. Limited Build Size
Most resin printers are typically limited to a smaller build volume than FDM printers. For example, many resin printers offer build sizes of around 120 x 120 x 200 mm. This makes them unsuitable for larger objects or full-scale prototypes. In 2025, larger resin printers are available, but they come at a significantly higher price point.
If you need to print large parts, FDM printing is still the better choice.
Comparing Resin vs FDM in 2025: Which One is Right for You?
1. Print Quality: Resin Shines for Detail
When it comes to print quality, resin printing has the edge. The precision and resolution offered by resin printers are unmatched by FDM. Whether you’re printing miniatures, detailed sculptures, or medical models, resin printing will give you the best results.
However, FDM has improved in recent years, with higher resolution options available at lower price points. But resin printers still excel in fine details that FDM cannot replicate, especially for items with complex geometries.
2. Cost: FDM Wins for Budget-Conscious Users
For hobbyists, makers, or anyone on a budget, FDM printing remains the more affordable option. The initial cost of an FDM printer is lower, and filament prices are much cheaper than resin. Additionally, FDM printers are easier to maintain, with fewer ongoing costs.
If you’re printing larger objects regularly, FDM is likely your best bet, as it provides an efficient, budget-friendly solution.
3. Ease of Use: FDM is More User-Friendly
In terms of ease of use, FDM printers tend to be more beginner-friendly. They have fewer post-processing requirements, and handling the filament is simple and straightforward.
On the other hand, resin printers require more effort for setup and maintenance. From handling toxic resins to dealing with post-curing and cleaning, resin printing demands more attention to detail.
4. Material Variety: FDM Wins for Flexibility
FDM printers are compatible with a wide range of materials, including PLA, ABS, PETG, TPU, and even filaments infused with carbon fiber, metal, or wood. This flexibility allows for functional parts, prototypes, and consumer products that can be tough, flexible, or lightweight.
In comparison, resin printing, while offering a variety of specialized resins, still has fewer options for creating functional parts. Most resins are inherently brittle, limiting their application to decorative objects and fine details.
5. Post-Processing: Resin is More Labor-Intensive
One of the biggest drawbacks of resin printing is the post-processing involved. After a print is complete, users must clean and cure it. This process can be time-consuming and requires the right equipment to do properly.
In contrast, FDM prints require little more than removing support structures and minor sanding. If you’re looking for a hassle-free printing experience, FDM will likely be more appealing.
