Filament Exchange

Got extra filament you’re not using? Trade it for something different at The Filament Exchange! This is the perfect way to swap unwanted spools with other makers and discover fresh colors, brands, or materials—all for free!

Find us at the 2026 Rocky Mountain RepRap Festival.
Located between the Polar Filament booth and the Filament Stories booth

How It Works:
● Exchange a spool for a ticket
● Come back anytime during the event to swap your ticket for a different spool

Rules:
● Any material is allowed
● 1.75mm filament only
● Must be on a spool (no loose coils)
● Full spools = 2 tickets, partial spools = 1 ticket
● Any unclaimed spools at the end of the event will be donated to local schools, makerspaces, and charity programs

Are you a school, makerspace, or nonprofit that could use filament donations?
Email [email protected] to be considered. You must be physically present at the event to receive a donation—no shipping available.
