EYE ON INNOVATION: Coffee Cup Made From Coffee Percolates With Investors

Nearly everyone loves coffee, right? But a coffee cup made from coffee? Really?

As it turns out, this cup is more about being green than any homage to coffee.

Fargo, North Dakota-based c2renew is seeking funds on Kickstarter for its c2cup: a travel coffee mug that’s made from a coffee biocomposite, using 30 percent recycled coffee grounds.

As of this week, the developers, who work out of a business and technology incubator at North Dakota State University, have garnered nearly $8,000 of a modest $20,000 goal, with a little more than a month remaining in the Kickstarter campaign.

We found this project intriguing because c2renew engineers are putting a twist on manufacturing processes like 3D printing and injection molding — and because we love coffee.

To develop the cup, the folks at c2renew created a biocomposite formula that is a hybrid of a bio-based resin and coffee waste. Developers claim that “this coffee biomass not only results in a greener plastic, it also cuts down on cost while maintaining the desired mechanical properties.”

TIPS WITH TONY: Fine-Tuning Your Additive Resolution

When you’re watching an epic movie filled with sweeping cinematography, you probably want the highest on-screen resolution possible with, say, a Blu-ray disc or high-definition stream. But if your children are watching old Disney movies in the playroom while arguing with each other over Legos, a standard picture from a classic DVD will probably suffice. The point: Don’t overpay for something that isn’t really necessary.

Normal resolution.

Normal Res
The same thought can be applied during 3D printing when you’re prototyping with stereolithography (SL). Proto Labs uses three resolutions that range in cosmetics and functionality. Normal resolution (NR) provides the lowest cost, but lacks fine detail. With NR you get a layer thickness of 0.004 in. with a minimum feature size of 0.010 in. — but that might be all you need in early prototyping.

High resolution.

High Res
If your part requires an elevated level of precision, there’s high resolution (HR). Here, you get a layer thickness (0.002 in.) and minimum feature size (0.004 in.) half of NR. It costs more, but the boosting the part quality may be well worth it depending on your intended application.

Micro resolution.

 

Micro Res
You can even step up to a higher level of precision, which most manufacturers are unable to provide. Micro resolution (MR) — the Blu-ray of additive resolutions, if you will — can provide optimal part detail on the smallest of part features. With MR, you get a layer thickness of 0.001 in. and minimum feature size of 0.002 in. Yes, that is an actual life-sized ant (not an evil oversized ant) atop a microscopic chess board. You can even see the staircase inside the rook!

EYE ON INNOVATION: Nebia Shower Uses Less Water, Makes Big Splash

Apple CEO Tim Cook and Alphabet (Google) Chairman Eric Schmidt are early backers of an eco-friendly shower system that transforms water into a kind of mist-and-water combo in an effort to reduce water consumption.

As Entrepreneur Magazine reports, the shower-head system, from San Francisco-based startup Nebia, is “blowing up on Kickstarter.” You think? As of mid-August, the project had received more than $2.1 million in pledged funds, from nearly 6,000 backers. The original goal was a modest $100,000. The Kickstarter campaign closes September 11.

How does it work? On its website, Nebia explains that its technology “atomizes water” into millions of droplets to create 10 times more surface area than a regular shower, giving you “the best of a steam room and an invigorating shower … you’ve taken thousands of showers, but never one like this.” Nebia claims that those who use the shower system will use 70 percent less water.

Harrison Weber, executive editor of VentureBeat.com, looking a little skeptical (okay, scared), recently agreed to “review” an early Nebia prototype.

As Wired Magazine recently reported, the science behind Nebia is more closely related to how farmers water their fields than how we clean ourselves every day, which, basically, is just a faucet that allows gravity to do all of the work.

Nebia designers repurposed nozzles that are typically used for agriculture, rocket engines, combination engines and other industrial means. The challenge was keeping the mist warm. Many prototypes later, this challenge was met through incorporating a code used for rockets. Designers began using modeling software from the aerospace and automotive industries. Indeed, it may not be just hyperbole when one reviewer of the shower claimed that Nebia’s product “blasts a steamy mist with the force of a miniaturized jet engine.”

TIPS WITH TONY: Machining Versus Molding for Magnesium Parts

In our latest tip, we’re talking about magnesium, and how to use it in product design for metal parts that need to be lightweight yet strong.

Magnesium works well for reducing component weight in place of steel or aluminum as it’s the lightest structural metal currently available. This lends itself well to a range of applications in the automotive, aerospace and electronics industries.

It’s heavily used in vehicle lightweighting to lower fuel consumption, reducing automakers overall carbon footprint. It’s also used to create lighter and thinner electronics or simply whenever a lightweight yet strong backbone material is needed in a part. Be sure to test and review magnesium’s material properties closely as it’s not always the proper substitute for other metal or plastic materials.

Magnesium versus

Steel

Aluminum

Plastic

75% lighter

33% lighter

Greater stiffness

Thinner walls

Similar or greater mechanical properties

Improved strength and wear resistance

Consolidation of parts

Consolidation of parts

Fewer supports needed

What manufacturing methods are there for magnesium? Proto Labs offers both CNC machining and injection molding for prototype and low-volume mag parts, though magnesium die casting also used in the industry.

How do I choose the right manufacturing method? Quantity, lead time, size and material properties will greatly impact which manufacturing method to use.

EYE ON INNOVATION: From Phones to Drones with Motorola’s ‘Flying Robots’

In 1973, Motorola demonstrated a prototype of the world’s first portable cellular telephone. By 2004, the company commemorated manufacturing its 30-millionth cell phone.

These days, Chicago-based (Schaumburg) Motorola Solutions, the direct successor to Motorola, Inc., is focusing its business on meeting a growing demand from law enforcement, military and other governmental agencies for high-tech intelligence and data-gathering tools. One prime example: Motorola is getting into the drone biz.

USA Today recently reported that Motorola is partnering with Danvers, Mass.-based CyPhy Works, a developer of tethered drones. These are drones that use a “microfilament tether,” allowing them to be powered through a generator or another power source on the ground and to stay in the air indefinitely.
