FDM
Advantages:
- Easy to operate and maintain
- Cost-effective and more economical compared to other methods
- Environmentally friendly, as it does not require the use of harsh chemicals
- Compact design, making it suitable for desktop placement
- No additional equipment is needed
- Supports a wide variety of materials
- Affordable equipment, which helps reduce product delivery time
Disadvantages:
- The surface often shows visible layering or texture
- Lamination quality can affect the physical strength of the final part
SLA
Advantages:
- Capable of achieving high precision and fine detail in parts
- The surface of the finished part is smooth with minimal layering visible
- Excellent for producing detailed small parts
- The integrated system is relatively easy to operate
- A wide range of materials with different properties can be printed
Disadvantages:
- Raw materials can be chemically irritating, pungent, and flammable
- Post-processing requires the addition of chemicals
- The material is sticky and can stain the surrounding environment
- Support structures are typically needed, which may leave marks on the surface
- Only one material and color can be used per print
- Limited print volume compared to other technologies
- Holes must be prepared in hollow parts to allow uncured resin to drain
SLS
Advantages:
- The finished parts have minimal powder residue and no visible layering
- Good mechanical properties in the finished parts
- No support material is needed
Disadvantages:
- The equipment is relatively large
- Protective masks are required during post-processing to prevent inhalation of powder
- Fewer material options and color choices compared to other technologies
- Equipment and materials can be expensive
- Powders need to be properly processed and recycled
- Most cost-effective when printing large volumes that fill the entire build chamber
Each of these three methods has its own advantages. Choose the most suitable one based on your specific needs.
