Nexa3D Acquires NXT Factory, Introduces Eco-Friendly 3D Printing Washing Solvent

While Nexa3D may specialize in manufacturing super-fast stereolithography 3D printers, the company has been branching out recently, and narrowing its focus on the materials side of things. It launched the high-performance polymer xCE-Black in May, followed soon after with the announcement of a partnership with Henkel to commercialize xMED412, a high-impact material for printing biocompatible medical and wearable devices. Now, Nexa3D has announced that xCLEAN, its new eco-friendly washing solvent for resin and photopolymer 3D printers, is commercially available.

“I am very proud of our entire team for stepping-up during this unprecedented pandemic, and  quickly pivoting internal developments and external collaborations to adeptly support our growing customer base and communities. “Throughout this challenging period, we’ve continued to expand the range of our high impact, durable photoplastics, and we are rolling out new productivity tools for the additive manufacturing industry,” said Nexa3D’s CEO and Co-Founder Avi Reichental. “Together with our growing partner network, we are committed to helping our customers improve their design agility, and supply chain resiliency by reducing the time required to produce functional prototypes and production parts from hours to just minutes.”

xCLEAN, compatible with most photopolymeric resin printers, including close loop systems, automated cleaners, and washing units currently on the market, and is safer to handle than other popular cleaning solvents, though it’s not been cleared to use in the cleaning of parts 3D printed out of biocompatible resins.


This material is easy to recycle, as well as recover with the help of a vacuum-assist distillation unit, and doesn’t need any of the typical adherence to shipping regulations or special storage that most post-processing photopolymeric parts require.

“xCLEAN’s development is a powerful reminder that necessity is the mother of invention. We were forced to explore alternatives to isopropyl alcohol (IPA) during the initial Covid-19 surge as IPA became extremely scarce and costs skyrocketed,” explained Nexa3D’s Head of Customer Success Brent Zollinger. ” After considering dozens of candidates, we zeroed in on xCLEAN and quickly embraced it as our go-to cleaning solvent. Having processed thousands of serial production parts in our flexible factory with superior results, we decided to share this incredible cleaner with our customers and invite the entire photopolymer 3D printing community to give it a try.”

Made from molecules that are smaller than DPM and TPM, xCLEAN is extremely effective, and doesn’t have any of the gross, greasy residue that you get with these two alternative materials; just rinse it off with water. It’s also sustainable, with three times the saturation limit of IPA, which means that it lasts three times as long and requires fewer changeovers and generates less waste.

xCLEAN can be ordered for immediate delivery here, or from one of Nexa3D’s authorized resellers. A single 5-gallon container will cost you about $320. To see the material in action, check out the video below:

But materials haven’t been the company’s only focus during COVID-19—the company just announced that it has acquired NXT Factory, which manufactures ultra-fast selective laser sintering (SLS) production systems powered by its proprietary Quantum Laser Sintering (QLS) technology.

“We are thrilled to join forces with Nexa3D and together unleash the power and potential of our products. COVID-19 propelled both of our companies to demonstrate the unique capabilities of our complementary additive manufacturing power as we quickly ramped into full production of personal protective equipment for frontline healthcare workers. This crisis has helped showcase the incredibly rapid and flexible nature of our combined additive manufacturing capabilities compared to traditional manufacturing and demonstrates how vulnerable the global manufacturing supply chain is to unexpected disruptions,” stated Kuba Graczyk, the Co-Founder and CEO of NXT Factory. “Together, we are committed to taking additive manufacturing to the next level and realizing its full potential.”

The two companies have entered into an agreement that states Nexa3D will acquire all the outstanding shares of NXT Factory, and the stockholders and boards of directors of both companies have approved the transaction, the details of which were not disclosed publicly.

By combining NXT Factory and Nexa3D’s high-speed technologies, the company is strengthening its capabilities and portfolio of production-grade materials. Nexa3D will now have access to NXT Factory’s range of powder fusion, supply chain-approved plastics, which will essentially double its addressable market and strongly position it for increased growth in the industry.

Leveraging its relationships with other key material suppliers, Nexa3D will be able to diversify its revenue streams by offering access to 100% of currently available polymer applications

“Stereolithography (SLA) and Selective Laser Sintering (SLS) are the cornerstones of additive manufacturing of plastics, so I am honored and proud to be part of the team that is uniting the two companies that are taking both technologies to their full potential. Having worked side by side with the Nexa3D team over the past four years in Ventura, California, sharing facilities, exhibiting jointly at tradeshows, witnessing untold technological breakthroughs and rapid expansion, there is no doubt in my mind that this is the perfect match for both of our companies. I am excited to join this dream team and contribute towards the creation of a leading fourth generation additive manufacturing powerhouse,” said Tomasz Cieszynski, Co-Founder and CTO of NXT Factory.

Subject to customary and other deal-specific closing conditions being met, the transaction should be completed as soon as practically possible.

Solvent Recycling for 3D Printers With Sidewinder Power

When you first launch your 3D printing business, you may not know about all the unique responsibilities you are taking on.  However, as soon as you dive deeper into the finishing process of printed products or parts, your knowledge of risk grows.  When you purchase any type of solvent for the finishing process, you become completely responsible for its safe handling, use, and disposal.  In order to minimize risk and save yourself a lot of money, a 3D printing solvent recycler would be a smart investment.

Over time you may accumulate gallons of unique solvent types such as IPA, Acetone, MEK, and Methyl Isobutyl Ketone.  Which will create a new task of proper disposal of these chemicals. None of these chemicals can simply be washed down the drain or tossed in the garbage.  There are both federal and state laws that determine the appropriate course of action with different types of solvents.  Whether you own and operate a large shop or manufacturing plant or are simply a small 3D printing business owner, you need to follow these laws or risk considerable repercussions that may include fines and incarceration.  Therefore, you should consider recycling your 3D printer solvents.

Purchasing a 3D printing solvent recycler will enormously reduce the difficulties of legal disposal.  The Sidewinder Model M-2 Solvent Recovery System was specifically designed and manufactured to help anyone interested in the 3D printing world reclaim their solvents responsibly and affordably.

It does not matter if you currently use ABS, PLA or resin to print your products or parts.  Different types of solvents are used to smooth and finish your projects.  The flexibility of the Sidewinder unit allows you to handle many types of solvents effectively while minimizing risk overall.  You do not have to transport them to another facility, pay for expensive hazardous waste removal, or even find a location to bring them to.

Instead, you can engage in safe and effective reclaiming of your solvents. The Sidewinder refrigeration reclaimer can handle acetone and other solvents used for smoothing and finishing your 3D printed projects. It is the only UL listed solvent recycler machine on the market which means it is a certified safe machine for indoor use. 

Sidewinder Solvent Recycler is Hassle-free and Easy to Use

As a 3D printer business owner, you probably prefer spending your time designing new 3D printed products and choosing materials rather than recycling solvents.  However, solvent recycling for 3D printers is a simple process when using the Sidewinder Model M-2.  It only takes three easy steps: 1. Load your used solvents; 2. Latch the lid securely; and 3. Press the On button.  The machine will manage the entire distillation process and output clean, usable solvent that can be used again and again.

Not only do you eliminate a lot of the disposal issues that come with using solvents for finishing 3D printed projects, but you also reduce your expenses when it comes to buying new solvents.

Ideally, the Sidewinder solvent recycling unit is for anyone who uses approximately 5 to 70 gallons of solvent per week.  Its sleek, efficient and compact design only requires a small footprint in your workshop or manufacturing facility.

According to the manufacturer, the Sidewinder can easily process about 50 gallons per week.  Although different variables are involved such as what solvents you are recycling and how dirty they are—along with humidity and barometric pressure—it may take a couple of hours to heat up, and then it should distill approximately one gallon per hour.  The manufacturer provides free phone support.

Enjoy Safety and Savings With Solvent Recycling

In order to maximize safety, this machine shuts itself off automatically once the recycling process is done.  It is UL listed and meets all applicable US standards required for solvent distillation machinery.  It does not require any special water hook-ups and can be cleaned with ease.

When it comes to saving money, recycling always makes more sense than paying for disposal and purchasing brand-new solvent for every project.  Although costs vary across the country the legal disposal of solvents usually runs around five dollars per gallon.  Therefore, the return on investment for the cost of the Sidewinder unit is around 3 to 4 months for anyone using 50 gallons of solvent per week.

How Does It Work?

A standard 5 gallon metal bucket of waste is placed in the chamber. Waste solvents are vaporized and re-condensed, making the solvent reusable. Vapors expand in the chamber, displacing air, and then fall through a refrigerated heat exchanger. After that, they condense and flow into the clean solvent receptacle. Waste stays behind in the cooking bucket. You can also use Sidewinder’s custom fitted processing bags which fit into the buckets like liners.

It’s important to note that this ‘cooker’ is meant only for commercial and industrial use by trained personnel. You never want to process unidentified compounds or anything containing acid. Do not process items containing nitrocellulose or cellulose nitrate. Always keep in mind that caution handling of hazardous waste is of utmost importance. You should find the Sidewinder to be simple and hassle-free, but also enjoy knowing that it comes with a one-year warranty. Is this a device you are interested in trying?
