As the 3D printing industry continues to grow and evolve, users are faced with an overwhelming array of options when it comes to choosing the right printing technology for their needs. Two of the most popular technologies on the market today are Resin and FDM (Fused Deposition Modeling) printing. While both types of printers have their own unique advantages and disadvantages, the decision of which one to choose ultimately depends on your specific requirements, preferences, and budget. In this article, we’ll delve into the details of both Resin and FDM printing, exploring their key differences, benefits, and limitations, to help you make an informed decision.
Understanding the Basics of Resin Printing
Resin printing, also known as Stereolithography (SLA), is a 3D printing technology that uses a liquid resin to create solid objects. This process involves the use of a laser or light source to cure and solidify the resin, layer by layer, resulting in a highly detailed and accurate print. Resin printing is known for its ability to produce prints with incredibly fine details, smooth surface finishes, and a high level of precision.
Key Benefits of Resin Printing
- High Resolution and Detail: Resin printing offers some of the highest resolutions available in 3D printing, making it ideal for applications where fine details and textures are essential.
- Smooth Surface Finishes: The liquid resin used in Resin printing allows for the creation of smooth, glossy surface finishes that are often unmatched by other printing technologies.
- Low Layer Thickness: Resin printing can achieve layer thicknesses as low as 0.01mm, resulting in prints with minimal visible layer lines.
Limitations of Resin Printing
- Post-Printing Process: Resin prints often require a post-printing process, involving washing and curing, to remove excess resin and achieve the desired finish.
- Toxicity and Safety Concerns: Some resin materials can be toxic and hazardous to health, requiring users to take necessary safety precautions when handling and printing with these materials.
- Expensive and Limited Material Options: Resin printing materials can be expensive, and the range of available materials is limited compared to other printing technologies.
Understanding the Basics of FDM Printing
FDM (Fused Deposition Modeling) printing is a 3D printing technology that uses melted plastic to create solid objects. This process involves the use of a heated extruder to melt and deposit plastic filament, layer by layer, resulting in a solid print. FDM printing is one of the most widely used 3D printing technologies, known for its affordability, ease of use, and versatility.
Key Benefits of FDM Printing
- Affordable and Accessible: FDM printing is one of the most affordable 3D printing technologies, with entry-level printers starting at under $200.
- Easy to Use and Maintain: FDM printing is generally easy to learn and maintain, with a wide range of resources and communities available to support users.
- Wide Range of Material Options: FDM printing offers a wide range of material options, including PLA, ABS, PETG, and more, each with its own unique properties and benefits.
Limitations of FDM Printing
- Lower Resolution and Detail: FDM printing typically offers lower resolutions and detail compared to Resin printing, resulting in visible layer lines and less precise prints.
- Warpage and Distortion: FDM prints can be prone to warpage and distortion, particularly when printing with certain materials or at high temperatures.
- Noise and Vibration: FDM printing can be noisy and produce vibration, particularly when printing at high speeds or with certain materials.
Head-to-Head Comparison: Resin vs FDM
When it comes to choosing between Resin and FDM printing, the decision ultimately depends on your specific needs and priorities. Here’s a head-to-head comparison of the two technologies:

| Surface Finish | Smooth, glossy | Can be rough, layered |
| Material Options | Limited, expensive | Wide range, affordable |
| Post-Printing Process | Required (washing, curing) | Optional (removing support, sanding) |
| Cost | Higher-end printers (>$500) | Entry-level printers (<$200) |
Who Should Choose Resin Printing?

Whether you’re a professional model maker, a hobbyist, or an educator, there’s a 3D printing technology out there that’s right for you.
What are the main differences between Resin and FDM 3D printing technologies?
Resin 3D printing technology uses a photosensitive resin that is cured layer by layer to create a solid part. It produces highly detailed and accurate parts with a smooth surface finish. FDM (Fused Deposition Modeling) technology, on the other hand, uses melted plastic to build parts layer by layer. It is a more widely available and affordable technology, but it can produce parts with layer lines and less detailed features.
The choice between Resin and FDM ultimately depends on the specific application and requirements of the project. If high detail and accuracy are required, Resin may be the better choice. However, if the project requires larger builds or a more affordable solution, FDM may be a better option.
