FD51-4PM – Polymaker Edition

FD51-4PM is a Polymaker exclusive design which was built from the foundations of FD51-4OS. It has specific material requirements which help improve performance along with the a increase in printing difficulty. It is the best free driver of the lineup, so if your picking filaments, this is a great candidate. Want more bass? Keep your eye on the upcoming WF81 series!

Kits for components will be made available on eBay once parts arrive

FD51-4PM, like all the the FD51 line up has a 80x3mm screw thread built in to it, allowing it to support all the cabinets available and make your own. They also support Thomas Sandladerer’s M3-SK project, so you can experiment with the drivers and cabinets to find what best suits you.
