Just like in almost every other industry, there’s been a rash of layoffs among newer space startups and companies amid the novel coronavirus crisis. But Relativity Space has managed to avoid layoffs — and is even hiring, despite the global pandemic. Relativity CEO and founder Tim Ellis cites the company’s focus on large-scale 3D printing and its adoption of cloud-based tools and technologies as big reasons why his startup hasn’t felt the pinch.
Because Relativity’s forthcoming launch vehicle is almost entirely made up of 3D-printed parts, from the engines to the fuselage and everything in between, the company has been able to continue producing its prototypes essentially uninterrupted. Relativity has been classified an essential business, as have most companies operating in anything related to aerospace or defense, but Ellis said that they took steps very early to address the potential threat of COVID-19 and ensure the health and safety of their staff. As early as March 9, when the disease was really first starting to show up in the U.S. and before any formal restrictions or shelter-in-place orders were in effect, Relativity was recommending that employees work from home where possible.
“We’re able to do that, partially because with our automated printing technology we were able to have very, very few people in the factory and still keep printers running,” Ellis said in an interview. “We actually even have just one person now running several printers that are still actually printing — it’s literally a single person operating, while a lot of the company has been able to make progress working from home for the last couple of weeks.”
Being able to run an entire production factory floor with just one person on-site is a tremendous competitive advantage in the current situation, and a way to ensure you’re also respecting employee health and safety. Ellis added that the company has already been operating between multiple locations, including teams at Cape Canaveral, Florida, as well as at Stennis Space Center in Mississippi and at its headquarters in LA. Relativity also had a further distributed workforce with a few employees working remotely from locations across the U.S, and it focused early on ensuring that its design and development processes could work without requiring everyone to be centrally based.
“We’ve developed our own custom software tools to just streamline those workflows, that really helped,” Ellis said. “Also, just being more of a cloud-enabled company, while still complying with ITAR and security protocols, has been really, really advantageous as well.”
In addition to their focus on in-house software and cloud-based tools, Ellis credits the timing of their most recent round — a $140 million investment closed last October — as a reason they’re well-situated for enduring the COVID-19 crisis. He says that Relativity not only managed to avoid any layoffs, while sending out new offers, but they’re also still paying all employees, including hourly workers, their full regular wage. All of this stems from a business model that in retrospect, seems prescient, but that Ellis says actually just has significant advantages in today’s global business climate by virtue of chance. Still, he does believe that some of Relativity’s resilience thus far signals some of the biggest lasting changes that will result from the coronavirus pandemic.
“What it’s really going to change […] is the approach to global supply chain,” he said. “I think there’s going to be a big push to have more things made in America, and then less dependence on heavy globalization across supply chain. That’s one you thing we’ve always had with 3D printing — not only is it an automated technology, where we can have very few operators still making progress even during times like like this and printing some of the first-stage structures of our rocket — but on the supply chain side, just having simpler supply chains with fewer vendors and different types of manufacturing processes means it’s much less likely that we’ll see very significant supplier and supply chain interruptions.”
Meanwhile, while Ellis says that ultimately they can’t predict how the coronavirus crisis will impact their overall schedule in terms of planned launch activities, which includes flying their first 3D-printed vehicle in 2021, they anticipate being able to make plenty of progress through remote work and a production line that can easily comply with social isolation guidelines. Partner facility shutdowns, including the rocket engine test stand at Stennis, will definitely have an impact, but Relativity’s resilience could prove a model for manufacturing businesses of all stripes to emulate once this moment has passed.

Zortrax has launched a new printer, the Inkspire, that prints using an LCD to create objects in high-quality resin in minutes. The printer – essentially an upgrade to traditional stereolithography (SLA) printers – uses a single frame of light to create layers of 25 microns.
Most SLA printers use a laser or DLP to shine a pattern on the resin. The light hardens the resin instantly, creating a layer of material that the printer then pulls up and out as the object grows. The UV LCD in the $2,699 Inkspire throws an entire layer at a time and is nine times more precise than standard SLA systems. It can print 20 to 36 millimeters per hour and the system can print objects in serial, allowing you to print hundreds of thousands of small objects per month.
“The printer is also perfect for rapid prototyping of tiny yet incredibly detailed products like jewelry or dental prostheses. But there are more possible applications,” said co-founder Marcin Olchanowski. “Working with relatively small models like HDMI cover caps, one Zortrax Inkspire can 3D print 77 of them in 1h 30min. 30 printers working together in a 3D printing farm can offer an approximate monthly output of 360,000 to over 500,000 parts (depending on how many shifts per day are scheduled). This is how Zortrax Inkspire can take a business way into medium or even high scale production territory.”

The printer company, which is now one of the largest in Central Europe, explored multiple technologies before settling on this form of SLA printing.
“At the early stage of this project we were investigating the technology itself, and it seemed very unlikely we were able to create such a device,” said Olchanowski. “We tried SLA and DLP but we were not happy with these technologies. We perceived them undeveloped. But, step by step, we succeeded. We see huge prospects of development for resin 3D printing technology, because nowadays customers expect the higher quality of printed models.”
The company sells 6,500 printers yearly and will see $13.7 million in revenue this year. They are also selling resins for their new printers and they will ship in about two months.
Printers like the Inkspire are a bit harder to use than traditional extruder-based printers like Makerbots. However, the quality and print speed is far better and paves the way to truly 3D-printed production runs for one-off parts.

3D Hubs, like MakeXYZ, was a community-based 3D printing service that let anyone with a printer sell their prints online. Founded in the heyday of the 3D printing revolution, the service let thousands of makers gather a little cash for making and mailing prints on their home 3D printers.
Now, however, the company has moved to a model in which its high-end partners will be manufacturing plastic, metal, and injection molded parts for customers willing to pay extra for a professional print.
“Indeed, more focus on high end printers run by professional companies,” said founder Brian Garret. “So a smaller pool of manufacturing locations (still hundreds around the world), but with more control on standardized quality and repeatability. Our software takes care of the sourcing, so companies order with 3D Hubs directly.”
Not everyone is happy with the decision. 3DPrint.come editor Joris Peels saw the value in a solid, dedicated community of hobbyists in the 3D space. The decision to move away from hobbyist printers, wrote Peels, “has confused many.”
“The value of 3DHubs is in its community; the community gives it granular local presence and a barrier to entry. Now it is just like any 3D printing service upstart and will lose its community entirely. I’ve always liked 3DHubs, although I have been very skeptical of their Trends Report I like the company and what they’re doing. I liked the idealism coupled with business,” he wrote.
The community, for its part, is angry.
A big F you to @3DHubs today! Switching over from “Locally sourced 3D prints” to the “Closed manufacturing program” basically… This was a big reason for me to own a 3d printer… now it’s all gone!

Why? Don’t you plan on screwing over the 3d printing community due to greed?

Sad news! @3DHubs is closing normal hubs (non Manufacturing Partners/Fulfilled by 3D Hubs). I’ve been pushing for months to get into the Fulfilled by 3D Hubs program, hope they give me one last change to join

The move will happen on October 1 when all prints will be completed by Fulfilled by 3D Hubs partners, dedicated merchants who will offer “source parts for larger, high value engineering projects.” The company wrote that during the early hobbyist days the “platform at that time was very much free-form, with the goal of serving as many, mostly one-off, custom maker projects as possible.”
This slow movement from hobbyist 3D printing to professional parts manufacturer is not surprising or unexpected, but it is jarring. The 3D printing community is small, vociferous, and dedicated to the technology. In the early days, when 3D printers were rare, it was tempting to buy a mid-price printer and become a small, one-person shop online. Now, with the availability of commodity printers that cost less than some paper printers, the novelty and utility of a low-resolution print has fallen considerably.
3D printing never fulfilled its promise in the home and small office. A one-off print can save some of us a trip to the machine shop or music store but in practice home 3D printing has been a bust.
Like most open source technologies that went commercial, the dedicated zealots will complain and the established players will pivot into profitability. It ruffles feathers, to be sure, but that’s how these things work. To paraphrase the White Stripes, “Well, you’re in your little room and you’re printing something good/ But if it’s really good, you’re gonna need a bigger room/ And when you’re in the bigger room, you might not know what to do/ You might have to think of how you got started sitting in your little room.”

Tocano, a spinout from Delft Technology University in the Netherlands which is working on an inkless printing technology, has closed a €1 million angel round to fund the next stage of its tech development and move a step closer to building its first commercial product.
The startup began as the graduate student project of co-founder Venkatesh Chandrasekar who, along with fellow student Van der Veen, founded the business in 2015, gaining early backing from the university.
The team now consists of eight employees and is part of the business incubator Yes!Delft.
Now it’s true there are already some ‘inkless’ printing technologies in use commercially. One we covered back in 2009 is Zink: A color printer which doesn’t require ink cartridges in the actual printer; but does require special Zink photo paper which has colored ink embedded in it. So an ‘inkless printer’, technically, but not actually ink-less technology.
Tocano’s tech — which it is branding Inkless — has a much cleaner claim to the name because it doesn’t involve having to use ink-saturated paper. Nor any other type of special paper, such as thermal-coated paper — which is another type of inkless printing already in use (such as for receipts).
Rather they are using an infrared laser to burn the surface of the paper — so carbonization is being used as the printing medium.
And they claim their technique is able to produce black and white printing with blacks as dark and stable as ink-based prints. Though, clearly, they’re still early in the development process.
Here’s a photo of their current prototype, alongside a sample of text printed with it:

The angel funding will be used to try to reach what they dub “a competitive printing performance”. After which they say they’ll need to raise more money to build the first product — so they’re already planning the next financing round (for the end of the year).
“With this money we can make our technology ‘development-ready’, which means that we can meet the required quality and speed performance requirements so that we can begin with the development of our first product”, says co-founder and CEO Arnaud van der Veen in a statement.
“[The] next round will either be financed by strategic partners or venture capitalists. The first meetings have already taken place.”
If they can successfully productize their laser carbonization technique the promise is printing without the expense, waste and limits imposed by ink refills plus other consumables.
“I always compare this to the transition from the analogue camera to the digital camera,” says van der Veen. “Suddenly people were able to make unlimited photos and it was not needed to replace the films. Likewise, with our printing solutions, refill and replacement of ink and consumables will not be needed.”
Though quite how expensive the next-gen laser printer machines themselves will be if/when they arrive on shop shelves remains to be seen.
Tocano says its first product will be aimed at industrial users for packaging and labelling use cases — such as printing barcodes, shelf life data and product codes on packages and labels.
Its ambition is to range out after that, bringing additional printer products to market targeting other business users — and eventually even the consumer market.
“Our first product will fit [the packaging/labelling] market but after that we will make the technology accessible for production printers, office printers, consumer printers and receipt printers. In all these market we can offer the same advantages, a cheaper and more sustainable printer without any hassle with ink, cartridges or toners,” he adds.

The promise of 3D printing has been kind of a dud. Aside from a few cool Yoda heads and some small plastic pieces, there have been no “indie” players doing much interesting in the space except Markforged. Markforged is a Boston company we featured last year that makes carbon-fiber reinforced plastic parts using traditional 3D-printing techniques. This means the objects they print… Read More

Makerarm is a robotic 3D printer, laser cutter, drawing and ink printer, fabricator and assembly machine all rolled into one that fits on a desktop and promises to make pretty much anything – including an entire laptop (It milled us the TechCrunch logo into a block of wood instead). Glowforge, a 3D laser cutter comes close but only offers laser cutting. Makerbot brings quality 3D printing… Read More
