FAQs

FDM 3D Printing:

1. What is FDM 3D printing?

FDM (Fused Deposition Modelling) is an additive manufacturing technology that creates objects by depositing layers of thermoplastic material, such as PLA or ASA, layer by layer.

2. How does FDM 3D printing work?

FDM 3D printers use a heated nozzle to melt and extrude plastic filament, which is then deposited layer by layer onto a build platform. The material solidifies as it cools, forming the final object.

3. What are the advantages of FDM printing?

FDM printing is known for its affordability, accessibility, and ease of use. It's great for producing durable, functional parts and prototypes.

4. What are the limitations of FDM printing?

FDM prints may have visible layer lines, and the level of detail is typically lower compared to resin printing. It can also be slower for intricate designs.

5. What materials can I use with FDM 3D printing?

FDM printers can use a variety of thermoplastic materials, including PLA, ASA, PETG, and TPU, among others.

Resin 3D Printing:

6. What is Resin 3D printing?

Resin 3D printing, also known as Stereolithography (SLA) or Digital Light Processing (DLP), uses liquid resin cured by UV light to create highly detailed, precise objects.

7. How does Resin 3D printing work?

In resin 3D printing, a light source, usually a UV laser or projector, selectively cures a liquid photopolymer resin layer by layer, creating intricate and precise parts.

8. What are the advantages of Resin 3D printing?

Resin printing offers high detail, smooth surface finishes, and excellent accuracy, making it ideal for detailed prototypes, miniatures, and jewelry.

9. What are the limitations of Resin 3D printing?

Resin printers tend to be more expensive and the resin itself can be toxic if not handled properly. They also have a smaller build volume compared to FDM printers.

10. What types of resins are available for 3D printing?

There are various resin types, including standard resins, flexible resins, and specialty resins with unique properties. Each is tailored for specific applications, such as dental, jewelry, or engineering.

These FAQs provide a basic understanding of both FDM and Resin 3D printing technologies, their advantages, and their limitations. When choosing between them, consider your specific project requirements and budget to determine which 3D printing method is best suited for your needs.
