Silicone 3D printing startup Spectroplast spins out of ETHZ with $1.5M

3D printing has become commonplace in the hardware industry, but because few materials can be used for it easily, the process rarely results in final products. A Swiss startup called Spectroplast hopes to change that with a technique for printing using silicone, opening up all kinds of applications in medicine, robotics and beyond.

Silicone is not very bioreactive, and of course can be made into just about any shape while retaining strength and flexibility. But the process for doing so is generally injection molding, great for mass-producing lots of identical items but not so great when you need a custom job.

And it’s custom jobs that ETH Zurich’s Manuel Schaffner and Petar Stefanov have in mind. Hearts, for instance, are largely similar but the details differ, and if you were going to get a valve replaced, you’d probably prefer yours made to order rather than straight off the shelf.

“Replacement valves currently used are circular, but do not exactly match the shape of the aorta, which is different for each patient,” said Schaffner in a university news release. Not only that, but they may be a mixture of materials, some of which the body may reject.

But with a precise MRI the researchers can create a digital model of the heart under consideration and, using their proprietary 3D printing technique, produce a valve that’s exactly tailored to it — all in a couple of hours.

Although they have created these valves and done some initial testing, it’ll be years before anyone gets one installed — this is the kind of medical technique that takes a decade to test. So in the meantime they are working on “life-improving” rather than life-saving applications.

One such case is adjacent to perhaps the most well-known surgical application of silicone: breast augmentation. In Spectroplast’s case, however, they’d be working with women who have undergone mastectomies and would like to have a breast prosthesis that matches the other perfectly.

Another possibility would be anything that needs to fit perfectly to a person’s biology, like a custom hearing aid, the end of a prosthetic leg or some other form of reconstructive surgery. And of course, robots and industry could use one-off silicone parts as well.

There’s plenty of room to grow, it seems, and although Spectroplast is just starting out, it already has some 200 customers. The main limitation is the speed at which the products can be printed, a process that has to be overseen by the founders, who work in shifts.

Until very recently Schaffner and Stefanov were working on this under a grant from the ETH Pioneer Fellowship and a Swiss national innovation grant. But in deciding to depart from the ETH umbrella they attracted a 1.5 million Swiss franc (about the same as dollars just now) seed round from AM Ventures Holding in Germany. The founders plan to use the money to hire new staff to crew the printers.

Right now Spectroplast is doing all the printing itself, but in the next couple of years it may sell the printers or modifications necessary to adapt existing setups.

This Thiel Fellow thinks he can help scooters, drones, and delivery robots charge themselves with sunlight

From the time he was a high school student, Rohit Kalyanpur thought it was peculiar that although it’s possible to create energy from a solar panel, the panels have long been used almost exclusively on rooftops and as part of industrial-scale solar grids. “I hadn’t seen [anything solar-powered] in the things people use every day other than calculators and lawn lights,” he tells us from him home in Chicago — though he’s moving to the Bay Area next month.

It wasn’t just a passing thought for Kalyanpur. Through research positions in high school, he continued to learn about energy and work on a solar charging prototype — initially to charge his iPhone —  while continuing to wonder what other materials might be powered spontaneously just by shining light on it.

What he quickly discovered, he says, is there were no developer tools to build a self-charging project. Unlike with hardware projects, where developers can turn to the open-source electronic prototyping platform Arduino and Raspberry Pi, a now seven-year-old, tiny computer the size of a credit card and was created to help students understand how computers work, there was “nothing you could use to optimize a solar product,” he says.

Fast forward, and Kalyanpur says there is now.

After attending the University of Illinois at Urbana-Champaign for two years and befriending a fellow student, Paul Couston, who helped manage and invest the university’s $10 million green fund, the pair dropped out of school to start their now four-person company, Optivolt Labs. Entry into the accelerator program TechStars Chicago was the impetus they needed, and they’ve been gaining momentum since. In fact, Kalyanpur, now 21, was recently given a Thiel Fellowship, a two-year-long program that includes a $100,000 grant to young people who want to build new things, along with a lot of mentorships and key introductions.

Now, the company has closed on a separate $1.75 million round of seed funding from a long list on notable individual investors, including Eventbrite cofounders Kevin & Julia Hartz: TJ Parker, who is the founder and CEO of PillPack (now an Amazon subsidiary); Pinterest COO Francoise Brougher: and Jeff Lutz, a former Google SVP.

What they’re buying into exactly is the promise of a scalable technology stack for solar integration. Though still nascent, Optivolt has already figured out a way to provide efficient power transfer systems, solar developer and simulation tools, and cloud based API’s to enable fleets of machines to self charge in ambient light, says Kalyanpur. Think e-scooters, EV’s, drones, sensors, and other connected devices.

Kalyanpur is hesitant to dive into too many specifics, but he says the company is will begin testing its technology soon with a number of “enterprise fleets” that have already signed on to work with Optivolt in pilot programs.

If it works as planned, it sounds like a pretty big opportunity.

Though some companies have begun making smaller solar-powered vehicles, you can imagine that there are plenty of outfits that would prefer to find a way to retrofit the hardware they already have in the world, which Kalyanpur says will be possible. He says they can use their existing batteries, too — that the solar won’t just power the devices or vehicles in real time but allow them to store some of that energy, too.  Optivolt’s technology “seamlessly integrates into everyday products, so you don’t have to change the product design meaningfully,” he insists.

We’ll be curious to see if see if it does what he thinks it can. Sounds like we aren’t the only ones, either.

Asked about Optivolt’s road map, Kalynapur suggests that one is coming together.

The company’s top priority, however, it to see first how it works in the field.

DoorDash reveals details of its new tipping model

DoorDash announced last month that it would be changing its controversial tipping model. Today it’s revealing the basics of how the new system will work.

Under the past model, Dashers (DoorDash drivers and other delivery people) were guaranteed a minimum payment per delivery, with DoorDash paying a $1 base, then providing an additional payment boost when a customer’s tip wasn’t enough to meet the minimum — a system that made it seem like tips were being used to subsidize DoorDash payments.

Under the new system, meanwhile, DoorDash will pay a base between $2 and $10 (the amount will depend on things like delivery distance and duration), with additional bonuses from DoorDash.

Most crucially, as CEO Tony Xu put it in a blog post, “Every dollar customers tip will be an extra dollar in their Dasher’s pocket.”

Now, you might think that’s how tips are always supposed to work, but Xu said the old system was developed “in direct response to feedback from Dashers,” while the new one will result in “greater variability in total earnings from order to order” (that variability several reasons why tipping is a flawed compensation model in general).

So why change?

“We thought we were doing the right thing for Dashers by making them whole if a customer left no tip, but the feedback we’ve received recently made clear that some of our customers who were leaving tips felt like their tips didn’t matter,” Xu said. “We realized that we couldn’t continue to do right by Dashers if some customers felt we weren’t also doing right by them. To ensure that all of our users have a great experience on DoorDash, we needed to strike a better balance.”

Plus, he said, “Dashers will [now] earn more money on average — both from DoorDash and overall.”

The company plans to roll out these changes to all Dashers next month.
