SLS 3D Printing
Selective Laser Sintering (SLS) 3D printing has long been perceived as expensive and out of reach for small businesses and startups. However, with recent advancements like the Formlabs Fuse 1+, the landscape is changing dramatically.
Cost and Accessibility
While traditional SLS setups may require investments of $40,000 to $60,000 for a complete system (including essential equipment like sifters and blasters), the Fuse 1+ now makes entry into SLS printing possible for about $20,000 for the base unit.
This shift makes SLS viable even for businesses with smaller budgets, opening doors for startups and established enterprises alike.
Why Should Businesses Consider SLS Printing?
The Fuse 1+ offers a streamlined workflow, producing highly accurate, robust parts with minimal effort. Unlike traditional FDM printing, SLS requires no bed adhesion, no supports, and minimal supervision, making it ideal for batch production.
For businesses producing parts in materials like Nylon 11, Nylon 12 Tough, or Carbon Fiber, the savings can be significant when compared to traditional injection molding — especially for small to medium production runs.
Material Options for SLS Printing
SLS 3D printers are capable of printing a wide range of materials, including:
- Nylon 12 Tough – Durable and versatile.
- Nylon 11 Carbon Fiber – For stronger, more heat-resistant parts.
- TPU (Thermoplastic Polyurethane) – Flexible material for specific applications.
Polypropylene has recently been discontinued by Formlabs due to inconsistent results, reflecting their focus on quality and reliability.
Maximizing Efficiency with the Fuse 1+
One of the Fuse 1+’s greatest strengths is its ability to maximize build volume. Users can load a full chamber with parts, press “print,” and return the next day to a completed run — a huge time-saver over traditional 3D printing methods that often require constant supervision.
This efficiency makes it especially useful for both short-run production and on-demand manufacturing.
The Micronics Acquisition: What It Means for the Future of Affordable SLS Printing
There has been some controversy regarding Formlabs’ acquisition of Micronics, a company developing lower-cost desktop SLS printers. While some feared this acquisition would suppress affordable SLS solutions, Formlabs has indicated they are working to expand accessibility rather than restrict it.
Micronics’ team has been integrated into Formlabs, continuing their mission to develop more accessible SLS systems with sustainable business practices.
Is SLS Right for Your Business?
If your company requires durable, production-ready parts with minimal manual intervention, SLS technology may be the perfect solution. While not for everyone, businesses seeking cost-effective alternatives to traditional manufacturing should explore the potential of SLS printing.
