3D printing technology has revolutionized the way we approach manufacturing, prototyping, and even home crafting. Among the most popular 3D printing technologies today are Resin and Fused Deposition Modeling (FDM) printers. Each of these has its strengths and ideal use cases, making them suitable for different kinds of projects. In this article, we will explore the best projects for each, helping you determine what to print based on the type of printer you own.
Understanding the Differences Between Resin and FDM 3D Printing
Before diving into the best projects for each type of printer, it’s essential to understand how Resin and FDM printers differ.
Resin 3D Printing
Resin 3D printers use photopolymer resin to create objects layer by layer. A laser or light source cures the resin, solidifying it to form intricate details. These printers are known for their high resolution and are capable of producing highly detailed and smooth prints.
Pros of Resin Printing:
- High precision and detail, ideal for small, intricate parts.
- Smooth surface finish, reducing the need for post-processing.
- Great for complex geometries and supports minimal structure.
Cons of Resin Printing:
- Generally slower than FDM printing.
- Requires post-processing to remove supports and cure the resin.
- Resin can be more expensive than filament.
FDM 3D Printing
FDM printers work by extruding melted filament, which is deposited layer by layer to build up the object. The material cools and solidifies as it is laid down. FDM printing is known for its versatility and cost-effectiveness, especially when working with various filament types.
Pros of FDM Printing:
- Faster than Resin printing.
- Cost-effective, especially with a wide range of filament options (PLA, ABS, PETG, etc.).
- Good for functional parts and larger prints.
Cons of FDM Printing:
- Lower resolution and rougher surface finish compared to Resin printing.
- May require support structures for overhangs, which can affect the final appearance.
Best Projects for Resin Printers
Now that you understand the differences between Resin and FDM printers, let’s explore the best projects to print with a Resin 3D printer.

Why Resin is Ideal:
- Exceptional detail and accuracy.
- Smooth finish reduces the need for extensive sanding or finishing.
- Ideal for artistic and intricate designs.
5. Prototyping Small, Complex Parts
Resin printers are great for prototyping small, complex parts that require a high level of detail and precision. Whether you’re working in engineering, product design, or innovation, Resin printing helps visualize prototypes that require an excellent fit and finish.
Why Resin is Ideal:
- Perfect for highly detailed and precise prototypes.
- Smooth surface finish minimizes the need for post-processing.
- Ability to print complex geometries.
Best Projects for FDM Printers
Now let’s shift focus to the best projects for FDM 3D printers. Due to their versatility and cost-effectiveness, FDM printers are ideal for a wide range of functional and larger-scale prints.
1. Functional Prototypes
FDM printers are fantastic for producing functional prototypes for various industries, including automotive, electronics, and engineering. These prototypes are often used to test the functionality and durability of parts before moving into production.
Why FDM is Ideal:
- Cost-effective for producing larger batches of prototypes.
- A variety of filament materials (PLA, ABS, PETG) allow for testing different material properties.
- Faster print times for larger, less detailed prototypes.
2. Home Décor Items
FDM printers can be used to create functional and decorative home items, including vases, planters, lampshades, and other unique designs. The wide range of filaments and ease of use make FDM printing perfect for these projects.
Why FDM is Ideal:
- Wide range of materials allows for different finishes and durability.
- Larger print volume allows for larger home décor items.
