From metal 3D printing to bespoke 3D printed eyewear. Find out more about this year’s nominees for the Forbes “30 Under 30” list.

Each year, Forbes magazine selects the top young entrepreneurs across a wide range of categories. The 30 Under 30 presents thirty game changing US entrepreneurs all aged under 30 years.

Presenting some of the brightest new talents, the list is now in its seventh year and has a global alumni network of almost 5,000. A whopping 15,000 nominations this year have been reduced to 600 spots marking an acceptance rate of just 4%.

The 20 categories with 30 honorees include Consumer Tech, Healthcare, and also Manufacturing & Industry. This year, three 3D printing businesses have made it into the top 30 nominees for the Manufacturing & Industry category. Let’s find out who they are.

Fabric8Labs

Fabric8Labs are making waves for their metal 3D printing capabilities. Founded by Jeff Herman and David Pain, the company has developed patented Stereo-Electrochemical Deposition as a process to produce 3D printed object in solid metals including copper, nickel, silver and gold – to name just a few.

The company does not use metal powders which make its products recyclable, less prone to porosity, and ultimately cheaper compared to other metal printing technologies. Due to the printing process not requiring any heat, metals and plastics can be printed together.

Fabric8Labs client list already includes aerospace and medical technology companies. It is supported by notable investors Asimov Ventures and Mark Cuban.

 Skelmet

Bespoke 3D printed eyewear has finally arrived thanks to Skelmet. The company is known for the Falcon 1 – a tailored pair of sunglasses that guarantees a true fit for sports fans or outdoor lovers. Launched by James Cao and Rain Wang, the company uses face scanning technology to 3D print the custom-made glasses. Buyers simply download the Skelmet scan app and get a friend to scan their face for them. They then take the scan to a partner shop and a trained associate will take the 3D scan.

Skelmet’s Indiegogo campaign launched earlier this year has already fetched $500,000 in sales.

Tyler McNaney – Filabot

Also featured as part of the 30 Under 30 is Tyler McNaney who founded Filabot back in 2011. His venture is a research and development company focused on furthering the science of plastic extrusion for the 3D market. As such, Filabot can take plastic materials and turn them into filaments to be used with 3D printers. Whether its old plastic bottles, plastic found on the beach or waste products from failed 3D prints – Filabot can recycle them all. It’s a winner for sustainability and the environment.
