What is SLS print?
What is SLS print?
SLS printing is the fastest additive manufacturing technology for functional, durable prototypes and end-use parts. The lasers that fuse the powder have a much faster scanning speed and are more accurate than the layer deposition methods used in other processes like industrial FDM.
How does SLS printers work?
The SLS 3D printer uses a laser as a energy source which selectively melts powdered plastic material, fusing them together into a 3D printed part. After the melting process is completed, the building platform is lowered, and a new layer of powder is added.
How expensive is SLS printing?
With a starting price of around $100,000 that goes well beyond that for the full solutions, traditional industrial SLS has been inaccessible for many businesses.
What are the disadvantages of SLS?
Selective Laser Sintering Disadvantages / Limitations
- Very expensive. The machines can often cost $250,000+, and the materials cost $50-60/kg.
- Cool-down time of 50% of print time can mean up to 12 hours of waiting. This leads to longer production time.
- Parts have a grainy surface without any post-processing.
What are the advantages of SLS?
SLS Advantages
- High levels of resolution.
- Fast turnaround times.
- Fantastic mechanical properties.
- High strength and stiffness.
- Wide selection of materials.
Is SLS cheaper than SLA?
Another factor is cost. SLA and resin-based printers are now available for less than $500 USD, while SLS machines are still well over $5,000 per unit. And in both designs, the cost is compounded over time, as the materials are often proprietary and quite expensive.
Is SLS or FDM stronger?
The largest difference in tensile strength between the two orientations was 10MPa, occurring at -60°C. Comparatively, the FDM parts tested at -60°C show a difference in tensile strength 30MPa greater than SLS.
Why is nylon used in SLS?
Nylon is ideal for complex assemblies and durable parts with high environmental stability. SLS 3D printed nylon parts are strong, stiff, sturdy, and durable. The final parts are impact-resistant and can endure repeated wear and tear. Nylon is resistant to UV, light, heat, moisture, solvents, temperature, and water.
Who manufactures SLS?
This series has been developed by the French manufacturer PRODWAYS, specialized in industrial and professional 3D printing. Specifically, the P1000 3D printer uses SLS technology to create parts with a maximum size of 300x300x300 mm.
