On Tuesday, classic computer collector Joe Strosnider announced the availability of a new 3D-printer filament that replicates the iconic “Platinum” color scheme used in classic Macintosh computers from the late 1980s through the 1990s. The PLA filament (PLA is short for polylactic acid) allows hobbyists to 3D-print nostalgic novelties, replacement parts, and accessories that match the original color of vintage Apple computers.
Hobbyists commonly feed this type of filament into commercial desktop 3D printers, which heat the plastic and extrude it in a computer-controlled way to fabricate new plastic parts.
The Platinum color, which Apple used in its desktop and portable computer lines starting with the Apple IIgs in 1986, has become synonymous with a distinctive era of classic Macintosh aesthetic. Over time, original Macintosh plastics have become brittle and discolored with age, so matching the “original” color can be a somewhat challenging and subjective experience.

Strosnider, who runs a website about his extensive vintage computer collection in Ohio, worked for years to color-match the distinctive beige-gray hue of the Macintosh Platinum scheme, resulting in a spool of hobby-ready plastic by Polar Filament and priced at $21.99 per kilogram.
According to a forum post, Strosnider paid approximately $900 to develop the color and purchase an initial 25-kilogram supply of the filament. Rather than keeping the formulation proprietary, he arranged for Polar Filament to make the color publicly available.
“I paid them a fee to color match the speaker box from inside my Mac Color Classic,” Strosnider wrote in a Tinkerdifferent forum post on Tuesday. “In exchange, I asked them to release the color to the public so anyone can use it.”
