Understanding the Basics of 3D Printing and Resin Printing
Before diving into the comparison, it’s essential to understand the basics of both technologies.
Fused Deposition Modeling (FDM) 3D Printing
FDM 3D printing is the most common type of 3D printing technology. It works by extruding melted plastic through a heated nozzle, which is then deposited onto a build platform layer by layer. The plastic cools and solidifies, forming a solid bond with the previous layer. This process is repeated until the entire object is printed.
FDM 3D printing is known for its:
- Affordability: FDM 3D printers are generally cheaper than resin printers.
- Ease of use: FDM 3D printing is a relatively simple process, and many printers come with user-friendly interfaces.
- Versatility: FDM 3D printing can produce a wide range of objects, from prototypes to functional parts.
Stereolithography (SLA) and Digital Light Processing (DLP) Resin Printing
Resin printing, on the other hand, uses a laser or projector to cure liquid resin layer by layer. The resin is photosensitive, meaning it hardens when exposed to light. This process creates highly detailed and accurate prints with smooth surface finishes.
Resin printing is known for its:
- High resolution: Resin printing can produce prints with incredibly high resolution and detail.
- Smooth surface finish: The cured resin creates a smooth, glossy surface finish.
- Accuracy: Resin printing is ideal for printing small, intricate parts with high accuracy.

Which is Better, 3D Printer or Resin Printer?
So, which is better, a 3D printer or a resin printer? The answer ultimately depends on your specific needs and applications.
- If you’re looking for a affordable, easy-to-use printer for prototyping and model making, an FDM 3D printer may be the better choice.
- If you need high-resolution, highly detailed prints with smooth surface finishes, a resin printer may be the better choice.
Hybrid Printers: The Best of Both Worlds
In recent years, hybrid printers that combine FDM and resin printing technologies have emerged. These printers offer the best of both worlds, allowing users to print with both FDM and resin materials.
Hybrid printers are ideal for those who need the versatility of FDM printing and the high resolution of resin printing. However, they can be more expensive than single-technology printers.
Conclusion
In conclusion, both 3D printing and resin printing have their strengths and weaknesses. While FDM 3D printing is ideal for prototyping and model making, resin printing is better suited for creating highly detailed and accurate prints.
