One of the best times of year for makers, the Prime Day sales from both Amazon and any other retailers that join in on the deals bonanza, is a great time to pick up some bargains to help you out in your maker journey. I've already spotted a bunch of great 3D printer deals, but what about the all-important filaments and resins to go along with them? We've scouted the internet to find you the best deals this Prime season, here are our best picks.

Some of the deals are discounts on individual spools of filament or bottles of resin, to bundle deals where you buy three and get one free. There is a wide selection of filament colors and types of filament, such as PLA, PLA plus, PETG, and more. The same goes for a variety of resin types. Do your research and choose what type of resin or filament will suit your maker project the best.

When checking out these deals, you will see that prices can vary wildly depending on the color of filament or resin you choose, so do double check the prices when you browse through the different colors, to make sure you're still getting a good deal.
