3D printing has stagnated, says designer Francis Bitonti.

The 3D-printing industry “is choking off its own revolution” with a combination of toy-like machines, over-priced materials and legal wrangles according to Francis Bitonti, the designer behind the printed dress for Dita von Teese.

“3D printing has just become incredibly stagnant,” said New York-based Bitonti, who feels that many of the machines on the market are little more than “tinker toys”.

A toy is not going to create the next industrial revolution,” he said. ”The biggest barrier that we have in the studio is just scaling products because the price points are so high.”

Printing materials are too expensive, he added: ”You’re paying 65 dollars for a kilogram spool of PLA, which is crappy plastic, and you can’t compete with injection moulding or any other type of production.

“They’ve got to open up,” he said. “It’s not that they need to open up all of their IP, but it’s a lot of things. You see a lot of tinker toys because they’re treating it like a copy machine. I think they need to change their mind and understand that it’s a manufacturing technology.”

He added: “The industry is just completely choked by intellectual property law right now.”
