Bluegrass

The Bluegrass is a 3D-printed putter from Appalachian Mountain Discs, made in Morristown, Tennessee, and printed in a durable 95a TPU.

The PDGA approved it on March 2, 2026 under certification 26-32, recording a 21.0 cm diameter, 1.5 cm rim, 1.6 cm height and 1.3 cm rim depth.

Appalachian Mountain Discs has not published flight numbers itself, but retailer Throwmore lists the Bluegrass at 3/5/-1/1 and notes that an official product description and plastic name are still to come. The printed TPU construction means feel varies with the print rather than with a named plastic family.
