Speed, size give Nexa3D printer leg up on large volumes

With a print volume about four times larger than the original Xip, the Xip Pro made its official debut in May at Rapid + TCT. It prints about 33 percent more quickly than its smaller sibling, and it can work within an automated ecosystem that allows users to manufacture multiple parts at once. 

The aim is a printer that “can get us beyond … 10,000 into the hundreds of thousands [of parts],” said Michael Currie, Nexa3D’s chief product officer, during a company webinar about the new technology. 

Part quality is on par with injection molding, said Lewis Simms, head of industrial product marketing for Nexa3D. 

Using Nexa3D’s proprietary liquid-crystal-display (LCD)-based Lubricant Sublayer Photocuring technology, the Xip Pro focuses ultraviolet light on a pool of photopolymer liquid resin to transform it into structural plastic. 

Light-emitting diodes (LEDs) and LCDs have been used to build upon older methods of curing light-sensitive resins. Previous approaches used a laser source, with later methods employing a lamp source instead. 

sometimes exhibited, and it allows the printer to accurately generate pixels, no matter how big or small, Currie said.

“You’re able to get down to accuracies less than a human hair — less than half the human hair — with this level of detail,” he said. 

The Xip Pro represents an evolution toward larger-scale production capabilities, Mason observed. 

“The ultrafast printing that Nexa[3D] provides isn’t just the layer speed; it’s the actual build plate, and overall volume size,” he said. “So, I like both. I like the larger XY dimensions because I can get more things on the plate and print at a low-aspect ratio quickly. You could picture something that was rectangular; historically, I would have had to print that vertically, and it might have taken seven or eight hours to do that. Now, I can lay it down on the plate and print it in 30 minutes.” 

But the Xip Pro’s features ensure more than just fast prints. 

“With the Xip Pro, I think I’m probably printing 10 times faster than I was before. And what that also means is I have fewer design inputs; I don’t have to cut the mold into as many small pieces,” Mason said. 

“They can house not just one build, but multiple builds, of parts at each stage that you’re pumping through at volumes,” he said. 

Contributing to the printer’s speed is its software, Currie explained. 

“We have an onboard computer with lots of ample space for future opportunity for upgrades. And, as you know, software is a huge component of any piece of equipment now, and we will always be updating and developing new feature sets,” he said. 

The system allows users to manage prints across multiple printers at once. 

Like Nexa3D’s other open-platform printers, the resin-based Xip Pro uses a multitude of resins — making it compatible with many manufacturers’ applications.  

With the speed and quality it delivers, the Xip Pro provides more options for manufacturers, Simms said during the webinar. 

“Because those processes print so fast and use more-robust materials, they can provide the performance, as well ... because with 3D printing ...  you had to make a choice. You had to say, ‘If I want a really accurate, detailed, high-quality part, I’ve got to sacrifice speed, and it’s got to be super-slow,’ ” he said. “... The latest versions of resin 3D printing … speeds up that process, while still providing all that detail and accuracy and precision that you need out of a final production part. So, now, it’s printing without compromise.”
