Although it just launched in March 2025 (and is available in Q2 2025), there’s a lot to be excited about in the Suzy from Sinterit. The most talked about feature so far is price: it’s under $20K, which, considering the exit of Sintratec from the industry in mid-2024, makes it the most affordable SLS machine currently on the market.

This new Suzy SLS machine is a more affordable entry to the powder bed technology, the company says and aims to satisfy companies looking for small-scale production and prototyping in nylon.

Compared to the company’s Lisa X ($24,500), Suzy has the same build volume (130 x 180 x 330 mm) and the same laser power, 30W, but is 35% faster, printing at up to 20 mm/h compared to Lisa X’s 14 mm/h.

The Lisa X prints with nine materials, whereas Suzy only prints with one material so far, nylon PA12.

Sinterit’s Lisa X is the 3D printer manufacturer’s third SLS printer, introduced in late 2021, after the Lisa and Lisa Pro. Lisa X takes what made the Lisa Pro good and makes it better. After her makeover, Lisa X now offers a larger maximum print size (180 x 130 x 300 mm), a more powerful laser (30W vs. 5W), a wider material selection, and much faster print speeds. The new printer is up to 12 times faster than the Lisa Pro and can finish most print jobs in 24 hours, according to the manufacturer.

The speed doesn’t come at the cost of detail quality since the Lisa X has the same 75-micron minimum layer height as its predecessor. The machine supports nine materials from Sinterit, but its open platform allows easy use of third-party powders as well. Although Sinterit says the Lisa X cools down quickly, it doesn’t have a removable build chamber, which means that you have to wait until the build fully cools before starting the next print.

If you’re someone who likes to fine-tune your print settings, you’ll appreciate Lisa X’s open software that enables you to change 32 printing parameters. This enables you to create your own material profiles and experiment with third-party powders outside of what Sinterit offers, so you can shop around for more affordable materials.

The Lisa X is marketed as a compact SLS printer, but it’s really bridging the gap between compact and industrial 3D printers. In addition to materials, another consumable is the chamber inert gas. The printer’s average inert gas consumption is 8 liters /min.

The Fuse 1+  is one of the most affordable SLS 3D printers from a maker with a reputation for reliable machines. It features a touch user interface and live stream monitoring of the print bed layer by layer. Formlabs says its “Surface Armor” technology forms a semi-sintered shell that prints around the surface of the part, providing good mechanical properties and a high-quality surface finish.

The Fuse 1+ 30W, which is the second version of the Fuse, launched in July 2022 and is twice as fast as the original Fuse. The laser on the Fuse 1+ is 3x more powerful than the Fuse, enabling it to produce with carbon-fiber infused PA11. In 2023, Formlabs introduced flexible TPU 90A powder to its menu and in 2024 launched a new polypropylene powder.

Formlabs’ New Printer Delivers Parts Twice as Fast

Both Fuse versions have the same build volume of 165 x 165 x 300 mm and a layer thickness of 110 microns. Combined with the Fuse Sift, it can provide a 30% to 50% powder refresh rate, driving down material costs. There’s the option to run the machine with air or an inert gas, which enhances some material properties and boosts the recyclability of the unused powder.

It could be a great option for manufacturers looking for affordable high quality.

Formlabs also offers two machines designed to take the labor out of post-processing SLS parts. The Fuse Sift is a station for extracting parts from the powder bed and collecting unsintered powder so it can be reused. The new Fuse Blast is a fully automated batch cleaning and polishing solution.

Sharebot SnowWhite 2 is the 2020 upgrade to the company’s previous SnowWhite unit. Its 14W CO₂ laser gives it the ability to print with a wider range of materials, including PA12, PA11, TPU, and reinforced powders that contain additives like carbon fiber, glass, and aluminum.

Geared toward research centers and R&D departments, the SnowWhite 2 is easy to use with an autonomous “one-click” user interface. Especially useful for research labs is the machine’s ability to use just 100 grams of powder to sinter a part.

SnowWhite 2 features an improved temperature control system, heating up to print temperature in just 15 minutes and providing high durability and surface detail. It also has an optional atmosphere control module that is compatible with both nitrogen and argon and eliminates yellowing in printed parts.

Priced at just under $40,000, this system is relatively expensive compared to other benchtop machines. It has a petite 100 x 100 x 95 mm build volume, making it one of the smallest SLS 3D printers on the market. The company doesn’t offer any post-processing stations so collecting the unused powder for reuse and cleaning arts has to be done manually or with a depowdering and polishing station from another vendor.

In May 2023, 3D printing giant 3D Systems acquired the Swedish SLS printer maker Wematter and incorporated the economical “Gravity” machine into its portfolio as the SLS 300. It’s no wonder 3D Systems snapped up this young company. It’s suite of hardware and software effectively brought SLS 3D printing to smaller manufacturers as an affordable turnkey unit.

The SLS 300 has a well-sized printing volume of 300 x 300 x 300 mm and is easy to operate thanks to an intuitive touch screen. There’s a cloud-based operating platform that requires no installation. The company says that through “new components and algorithms”, the scanning speed has been increased by two times compared to the previous model saving up to 15 hours on a typical print job.

The powder material is contained in cartridges, thus eliminating the hazard of fine particles. In fact, in 2024, 3D Systems is launching a “Powder Recycling Station” for the 300 that will automatically recycle unused powder currently in the system and mix it with fresh material and put it back into cartridges.

3D Systems also offers a curious unit called the Atmosphere that provides “improved control of build chamber conditions.” The Atmosphere communicates with Gravity’s software and creates a more stable thermal environment during the printing process, the company says. This optional unit is supposed to boost the Gravity’s performance for increased part density, surface finish, and mechanical performance.

For post processing, 3D Systems offers a unit that cleans and extracts powder using a water spray gun containing different nozzles to clean cavities, surfaces, and smaller details. The Water Jet Cabinet uses 20 liters of tap water that recirculates, just plug it in, fill it with water, and get started. No running water or drain connections needed.

Although the printer retails for around $50K, the full ecosystem is closer to $70K – $90K.

Sinterit’s Nils 480, the big brother to the Lisa series listed above, delivers industrial speed (full bed printing in 30 hours) and size (200 x 200 x 330) enabling you to print, for example, a whole shoe, housing of most electronic devices, or a whole arm orthosis.

The Nils 480 includes many of the features that made the Lisa line popular, including a wide range of material options from PA12 to PP to TPU, plus third-party powders; an open parameter environment with more than 30 settings to control; and intuitive software.

In essence, if you like the Lisa X but wish it were bigger and faster … here you go.

The Nils also features what the company calls a Continuous Printing System, where you fill the powder once and print two full beds or a few lower-volume print beds all without repeating the print preparation process and powder filling. To do this, the previous bed automatically ejects, lifting a full cake to the cooling box. The printing bed comes back and another print automatically begins. Potentially, you could print two full volumes over the weekend, unmanned.

For post-processing, the Nils 480 can be paired with the same cleaning and powder management units from Sinterit that are offered with the Lisa series.

Farsoon Technologies’ polymer SLS technology comes in six configurations. Its eForm SLS machine is billed as the entry-level system with all the functionality and power of an industrial-level system, the company says.

The eForm comes with an easy-to-use touch-screen-based UI configuration for a production environment. Like most of the other SLS printers on our list, the eForm has optional powder handling units.

The larger 403P machines (HS403P, SS403P, and HT403P) all have an eight-zone heater and thermal controls to ensure an even temperature and minimize risks of inaccuracies. The HT model is built for processing high-performance materials, like PA 6, at high temperatures and features enhanced temperature shielding and thermal controls. The HS model is the – relatively speaking – budget option of the trio.

Farsoon also offers the industry’s largest SLS 3D printer, the HT1001P-2, which has a build volume of 1,000 x 500 x 450 mm and features two 100W CO₂ lasers. There are two more SLS printers in the company’s 252P series, which have the same compact build volume as the eForm but various temperature and laser features.

Farsoon is also a member of the Cold Metal Fusion club, hoping to offer customers the ability to 3D print metal parts on its SLS units. To date it has qualified the material but not officially rolled it out as an option. In late 2023, Farsoon also announced that it was offering the Cold Ceramic Fusion process on its  SLS platform HT252P that enables you to create ceramic parts.

Eplus3D has offered a lot of SLS 3D printers over the years but currently only features the EP-P420 outside of China, which launched in 2021. The company is best know for its metal powder bed fusion machines, of which it offers 12 options.

This machine looks to provide high productivity at a relatively reasonable price point. With a huge build volume and a laser four-times the power of desktop-size SLS machines, it is clearly marked for high-volume production. The 120W CO₂ laser makes for detailed models with high surface quality and dimensional accuracy.

The forming cylinder of the machine is detachable, which reduces standby time between print jobs and increases manufacturing and sintering efficiency. Open printing parameters allow for precise setting adjustment for specific applications.

EP-P420 supports a good variety of materials, making the printer suitable for several applications with differing requirements. With a uniform heat control system, the printer can deliver reliably optimized mechanical properties. It also provides high powder recycling rates, which helps reach ROI faster.

The proprietary Eplus3D control software overseas printing process management, from build preparation and part positioning to printing monitoring and report generation function.

Manufactured by industrial 3D printing pioneer EOS, the Formiga P 110 Velocis FDR, introduced in 2021, offers flexibility and cost-effective production to the manufacturing floor, the company says. This FDR version of the Velocis, which is the company most economical, is a bit slower that it’s other offerings and doesn’t offer the same material range, but has a powerful and precise laser leading to very detailed prints.

The P 110 FDR features temperature management and software control, which speed up the heating and recoating processes, the company says. It’s laser makes it possible to produce wall thicknesses of only 220 microns.

The full suite of SLS machines includes an EOS material mixing station, unpacking and sieving station, and blasting cabinet.

The Velocis versions are EOS’ entry-level SLS 3D printers, but the company offers four more with larger volumes and more powerful lasers: the P 396, P 500, P 770, and the Integra P450, which is only available in North America. The P 770 has two 70W lasers and is one of the largest SLS printer on the market with a build volume of 700 x 380 x 580 mm. The P 500 also has two 70W lasers and is a popular choice with manufacturers and 3D printing service bureaus.

Late last year, EOS, the German-based manufacturer of some of the world’s most popular industrial 3D printers, launched a new generation of its polymer selective laser sintering (SLS) platform to focus on productivity and cost efficiency while maintaining its established reputation for part quality.

The new EOS P3 Next is just that: the next version of EOS’ P 396 launched in 2016, but it’s more than an upgrade. The new system promises a 50% increase in productivity and a 30% reduction in costs compared to the P 396. Key features include a 36% faster “layer creation time”, the ability to swap out build units, and a high material reuse rate (80% with the new ALM PA 950 HD nylon 12 and 70% with EOS PA 2220 HighReuse).

Virginia Palacios, the chief business officer of EOS’ polymer solutions, told All3DP that this new machine hits an important target for volume manufacturing: machine uptime. She says the P3 Next delivers more than 90% machine availability.

When EOS says the P3 Next has 50% higher “efficiency” than the P 396, what that really means in concrete terms, is that you can get 50% more parts printed in a day, Palacios says.

“We are cutting the layer time 36% , cutting the heating time, cutting the dead time at the beginning and at the end of the build, and introducing a hot swap functionality, so that once the build is finished, we can take it out and start immediately the with next one, instead of having it cool for a long time in the printer,” says Palacios.

3D Systems has offered many SLS 3D printers over the years in various sizes but has recently reduced its offering to just the SLS 380, its most popular. One of the key elements of its claim to high repeatability and throughput is its management of heat. The machine has eight separately calibrated heaters to control the build chamber temperature.

The system uses a custom-developed algorithm to manage, monitor, and control in real-time, the thermal uniformity within the build chamber. There’s also an integrated high-resolution inferred camera that captures more than “100,000 thermal data samples” from within the build chamber per second, the company says. What all this boils down to is quite a bit of assurance that each layer is sintered according to plan, and should there be an error, you know which part of the batch it’s in. This level of production traceability is essential in larger manufacturing environments and regulated industries.

New to the SLS 380 is a water-cooled laser.

The 380 provides a large print chamber with a good build rate and a decent level of detail. It also has a counter-rotating roller to distribute powder more smoothly across the print bed, the company says.

The SLS 380 can be combined with 3D Systems’ Material Quality Center (MQC) to control material blend and delivery. The company offers the MQC Single to pair with one printer and MQC Flex which works with up to four printers simultaneously.

Unless you’ve gone through the hassle of manually collecting powder and hand-blending used powder with fresh powder in the right proportions, you may not realize what a convenience a machine that does this automatically is. In a production setting, it’s essential. The MQC Flex includes a recycled powder bin that provides convenient and immediate storage for unused powder post-printing.

If you’re not keen on 3D Systems powder handling solution, the company has partnered with AMT to provide a fully automated post-processing workflow, from de-powdering to vapor honing that it says delivers end-use parts in-hand faster.

Another brand new SLS definatey worth mentioning is the quad-laser Flight HT601P-4 from Farsoon. Aimed at large scale production 3D printing, the platform boasts high-speed, large-scale (600 × 600 × 600 mm) manufacturing with “advanced automation” to maximize production yield and reduce cost per part, the company says.

The four 300-watt fiber lasers deliver scanning speeds of up to 20 m/s to ratchet up productivity and efficiency. You can select “Efficiency Mode” for overlapping laser areas to boost productivity or “Quality Mode” for single-laser scanning to meet specific industry certification needs.

True to Farsoon’s philosophy, the Flight HT601P-4 features an open parameter strategy, enabling users to fine-tune material processing for unique applications.

There’s a exchangeable build cartridge that can cool outside of the printer, freeing it up for the next build. Aadjustable laser spot sizes enable you to save time with larger infill beams and precise detailing with smaller contour beams.

Professional SLS 3D printers cost anywhere from $7,000 to a $750,000, which is not a helpful answer at all, we know. The truth is that for machines in the $10K to $90K range, you’ll usually find a consistent and public sticker price.

However, when you get above $100K, and especially when you approach $250K, there can be many factors that affect the final price you’ll pay, such as customizations, options, your location vs. where the machine is manufactured (import duties, taxes), how many you’re buying, discounting for education, research, or case study partnerships, long-term agreements, marketing agreements, instillation and training, optional warranties, and more.

The price of one machine with every possible add-on and customization going to a high-cost location can be three times the price per unit of a 10-machine order to major city.

That said, manufacturers should provide you with a ballpark figure for your CapEx request upon first contact. OEMs don’t want to spend time and resources serving a potential customer when their machine is clearly out of reach, so early transparency on prices is a win-win.
