Massive Dynamics Inc., a designer and manufacturer of Apple and Android accessories, has signed a letter of intent to buy PrintForge 3D Ltd., a company that makes 3D printers.

PrintForge, based in Hong Kong, also makes scanners and printing-related software that produces objects by stacking layers of material, like plastic or metal, on top of one another.

Massive expects the deal to help it serve the manufacturing industry. The company, headquartered in Cupertino, Calif., plans to launch PrintForge’s products in the U.S. in the next few months.

Massive’s products include an iPhone case that contains an external battery, an accessory that adds phone lines to devices and 3D printers. 

Terms of the deal weren’t disclosed.
