"It's still too expensive for mass production," Moreau said. "If you want to produce millions of this kind of pigs, you'd better find a Chinese factory."

"3D printing is increasingly affordable," said Shapiro. "Every new technology is expensive at the beginning, but later generations would become cheaper."

"There are already hundreds of thousands of free applications of 3D printing and consumers are starting to buy 3D printers for their kids to create things", Shapiro added.

Moreau felt optimistic about his firm and the future development of 3D printing. He said Sculpteo had been operated for five years relying on investments, but next year, it was expected to achieve sound development through its own 3D printing business.

2014 International CES was opened on Tuesday morning and will last till Friday. It has attracted more than 3,200 exhibitors with their latest consumer tech products in 15 categories.
