Bradley Rothenberg, cofounder and CEO of nTopology, is building next generation design software that relies on mathematical computations to create 3D-printed parts and products that are lighter and more efficient than would be possible with older CAD systems. As 3D printing takes hold as a means for mass production in industries like aerospace, automotive and healthcare, his New York City-based startup expects revenue to more than triple this year, to $5 million, up from $1.5 million in 2019.
That’s still tiny, of course, but the market for this type of cloud-based generative design software is growing so fast that in June – six months earlier than expected and despite the pandemic – nTopology raised $42 million led by Insight Partners at a valuation of $140 million. The fresh capital will help nTopology, which has 82 employees, expand as industries including aerospace, automotive and healthcare adopt 3D printing for future products, such as electric vehicles.
“We’re the toolmakers behind the scenes enabling this whole industry to work,” says Rothenberg, 35.
The startup’s cloud-based software, which costs roughly $5,000 per user per year, has been used to redesign brackets for space satellites, to make more efficient spinal cages for back surgery and to rapidly create nasal swabs for Covid-19 testing during the pandemic, among other uses. Customers include Lockheed Martin (which is also an investor), Raytheon, BMW, Daimler, Trek Bikes, NASA and Lightforce Orthodontics.
As manufacturers turn to 3D printing to produce parts and products at mass scale, nTopology is part of an emerging industry of next-generation design software that includes products from Autodesk, Dassault Systemes’ Solidworks and PTC’s Frustum. The advanced computations in nTop’s software allow it to create structures that are hollowed out or have lattice designs that could only be created with
While scoping out a suspected subterranean lake hiding under the Martian soil, scientists stumbled across not one, not two, but three more of them encircling the original. And they’re not puddles by any means. The research team estimates the largest one to measure up to 19 miles across with the others topping out at a few kilometers apiece. But don’t expect to go swimming on the Red Planet in the near future — we’l have to bore through a kilometer of ice to get to it.
The COVID lockdowns have hit the American auto industry hard this year with demand dropping as people stayed home and off the road. However, that apparently is not the case with Tesla which announced last week it had crushed its previous quarterly delivery record by nearly 27,000 vehicles. Over all, the company has shipped some 318,000 automobiles so far in 2020.
If you thought that Trump campaign rallies were rife with COVID, let me introduce you to a little place called an Amazon distribution warehouse. The company announced last week that nearly 20,000 employees had contracted the virus since the start of the year which, out of Amazon’s 1.2 million-strong workforce doesn’t sound that bad. Unless of course you work in one in Minnesota, where the infection rate is more than three times that of the rest of the state.
Even though the president refuses to denounce militants and white supremacists in this country — telling his militant mob of Proud Boys supporters to “stand down and stand by” during Tuesday night’s debates, — Facebook isn’t tolerating their presence on its site. Throughout August and September, the social media platform identified and wiped more than 6,500 pages and groups tied to militant movements and QAnon.
