BROOKLYN, NY, June 10, 2021 – MakerBot, a Stratasys company, introduced its new Clean Air smart filtration system. The new system is part of MakerBot’s continued efforts to develop and deliver 3D printing solutions that support industry safety, sustainability, and compliance practices.
The MakerBot Clean Air System is a smart-controlled HEPA filtration system for the MakerBot METHOD and MakerBot METHOD X 3D printers. The MakerBot Clean Air System includes a HEPA filter designed to filter ultra-fine particles during the printing process. Internal testing at MakerBot shows that the MakerBot Clean Air System removes up to 95% of ultra-fine particles compared to printing without the accessory. The system seamlessly integrates into METHOD’s intuitive workflow by automatically controlling the HEPA lid and accounting for ambient conditions, chamber temperature, and model material.
The METHOD, METHOD X and SKETCH 3D printers already come equipped with several safety features. Each printer features enclosed build chambers, which will prevent users from being able to touch the parts or extruder when printing. METHOD will automatically pause during the printing process when its chamber door is opened. SKETCH also features a built-in particulate filter designed for safer printing in school environments.
“We are committed to being world-class in safety as we advance 3D printing’s use worldwide,” said Nadav Goshen, CEO, MakerBot. “From meeting industry certifications to delivering 3D printing solutions that support safety, our goal is always to exceed global industry benchmarks.”
The MakerBot Clean Air System is now available. For more information, visit https://www.makerbot.com/3d-printers/method/cleanair/
Founded in 2009, MakerBot was one of the first companies to make 3D printing accessible and affordable with our first 3D printer, the Cupcake CNC. In 2010, we became the first company to present a 3D printer at the Consumer Electronics Show (CES). Now, 3D printing is its own category there with a myriad of 3D printing companies in attendance each year. After being acquired by Stratasys in 2013, they introduced the first Wi-Fi connected desktop 3D printer in 2014.

for F110 Additively Manufactured Sump Cover
CINCINNATI, OH, June 10, 2021 – GE Aviation has received Engineering Change Proposal (ECP) approval from the US Air Force (USAF) for an F110 additively manufactured sump cover. The latest milestone in the USAF and GE’s pathfinder Pacer Edge program, this F110 component is the first engine component designed for and produced by metal additive manufacturing to be qualified by any US Department of Defense entity.
“Much like the GE90 T25 sensor that was an FAA certification pathfinder for metal additive manufacturing for GE Aviation in commercial aerospace, the F110 sump cover sets a solid foundation for many more additively manufactured component qualifications with GE’s military customers,” said Matt Szolwinski, chief engineer and leader of GE’s Large Military Engineering team.
“The Pacer Edge program is an important initiative for reducing risk and showcasing the application of additive manufacturing in aerospace. The ability to additively manufacture an aircraft engine part and gain military airworthiness is a significant step forward in growing the adoption of additive manufacturing in the Air Force,” said Nathan Parker, deputy program executive officer for the USAF RSO.
“The Chief of Staff of the Air Force, General Charles Q. Brown, Jr., has challenged us to ‘accelerate change or lose.’ The entire Pacer Edge process is built around the ‘accelerate change’ philosophy, and the speed of the F110 sump cover development and airworthiness approval is evidence of that. The capability that Pacer Edge is demonstrating and proving will be a game changer to engine production and sustainment and will resolve many future Air Force readiness challenges,” said John Sneden, director of the USAF’s Directorate of Propulsion.
Spiral development enhanced by experience and a digital thread
The airworthiness qualification of the sump cover brings Pacer Edge Phase 1a of the pathfinder to its conclusion. Part of the key to the accelerated qualification — in under a year — was GE’s decade of metal additive engineering and manufacturing expertise.
The team’s in-depth knowledge of commercial aerospace engine airworthiness for flightworthy 3D printed metal parts is proving instrumental in helping USAF establish its own robust process validation and certification processes for military airworthiness.
Close collaboration and knowledge sharing have enhanced USAF’s spiral development approach of continuously identifying, reverse engineering and developing technical data packages (TDPs) for increasingly complex and larger parts suitable for metal additive manufacturing.
“USAF’s strong vision for additive as part of its wider sustainment and readiness strategy has allowed our combined team to progress at speed. We continue to share our learnings and have developed an efficient, structured way of working — especially for developing qualification processes and expediting design iterations. This lean, operational efficiency is already driving results and now sets us up for the next phases of the program, including looking at complex and large format, load-carrying structures,” said Szolwinski.
Phase 1b is already underway and focuses on an out-of-production sump cover housing on the TF34 engine, which has been in service more than 40 years.
“We’re thrilled to be on this journey with USAF. Additive journeys are great, but even better when you have a good map and experienced guides. We started with a relatively easy part, but the spiral development model is coming into its own. It provides focus for the team and our experts help navigate and problem solve along the way,” said Lisa Coroa-Bockley, general manager for GE’s Advanced Materials Solutions.
A digital thread also runs through the pathfinder. GE experts focused on digital twinning, maintenance-based predictive analytics and part lifecycle management expertise have been able to complement the USAF’s digital engineering strategy and in-house knowledge.
“Human interaction and collaboration both add immense value to our work, but digital is the enabler. Additive is a powerful digital technology that spans the entire process, from design and modelling, to in-situ monitoring through to inspection and final level assurances,” added Coroa-Bockley. “Adding digital twinning and predictive analytics on top brings new horizons into view, such as systems management, diagnostics and repair of in-field systems.”
Tinker AFB as airworthiness metal additive supply chain hub
“Subsequent phases of the Pacer Edge program involves the establishment of a metal additive manufacturing supply chain at Tinker Air Force Base in Oklahoma, capable of producing airworthy components in support of the DoD’s sustainment needs,” said Lauren Tubesing, director – military accounts at GE Additive.
Recently, the Air Force’s Propulsion Directorate and RSO invested $10M to fund additional phases of the Pacer Edge program, leveraging the Defense Logistics Agency’s (DLA) Captains of Industry contract vehicle.
This funding will accelerate the development of the USAF’s organic AM capability and capacity to design and print flightworthy hardware for military engines, aircraft and support equipment. The Pacer Edge team is utilizing this capability to alleviate hard-to-source and obsolete spare parts constraints for legacy systems.
“The F110 sump cover was a terrific pathfinder, allowing us to exercise the USAF’s airworthiness process. There are numerous parts in queue that are ideal candidates for metal 3D printing. Next, we are focused on refining the airworthiness process, so it is as responsive as the technology,” said Melanie Jonason, chief engineer for the USAF’s Propulsion Sustainment Division.
