While the cost of your next 3D printer may be going up in the U.S., the cost of your filament doesn't have to increase. Or that is, it won't if you buy American. Many customers in the U.S. are bemoaning the impact of President Trump's tariff war on their favorite hobby, with new 3D printers possibly going up hundreds of dollars or remaining mysteriously out of stock.
Polymaker, a global supplier of affordable filament, recently announced that it will be forced to increase prices by 10% on May 1st. In a statement issued on its website, Polymaker said it reviewed the amount of stock sitting in U.S. warehouses before making the difficult decision to hike prices to compensate for tariffs.
I had the chance to talk to Polymaker representatives at Rapid + TCT in Detroit earlier this month and ask them if the new Houston, TX plant would help keep costs down. The answer was yes and no. Unfortunately for the average consumer, the Texas facility specializes in wholesale cus tomers and only produces PLA, PETG, ABS, and ASA in limited colors. You also have to buy over $1,000 in materials to place a wholesale order. But if that's you, congratulations, your prices are holding steady.

Many American filament manu facturers are able to keep their supply chain domestic thanks to NatureWorks, a U.S. plastics company that creates raw PLA pellets from Nebraska-grown corn.
American filament companies are taking advantage of the tariff talks to remind customers that they can always buy local. Polar Filament in Troy, MI announced on social media that pricing would remain the same, as its entire supply chain is US-based.
"So far, we've confirmed that the most critical components, including the resin (the raw plastic pellets), colorants, spools, and even the paper used in our boxes, are all sourced domestically. We're also setting up our own injection molding machine so we can make spools right here at our facility," said Mitch Davis in the statement.
Polar Filament currently sets its price for Basic PLA at $18.99 and $21.99 for premium colors, besting Polymaker's price by several dollars. Free shipping for US customers kicks in after three spools.

I also stopped to chat with New York-based GreenGate manufacturer Rich Silberfeld during Rapid + TCT in Detroit. GreenGate makes premium recycled PETG filament that can easily print at lower PLA temperatures. Silberfeld said his filament not only saves plastic scraps from going into the landfill, but also uses domestic colorants and spools. He was showcasing a special color, Spartan Armor Green, in honor of Michigan State University while stationed in the America Makes section of Rapid + TCT.
GreenGate is running a sale on the American Bundle, a three-pack of Red, White, and Blue PETG, which also includes free shipping and a t-shirt, for just $86.37.
