Copper3D PLACTIVE AN1 2.85mm Red Copper Oxide Nanocomposite Infused PLA 3D Printer Filament. Ideal for 3D Printing Reusable Face Masks and Door Openers, Dimensional Accuracy < +/- 0.05mm

Not the cheapest stuff, but prints great and I love the color. I’ve used to to print some accessories for the kitchen sink and bathroom. I wish there was more supporting data to prove the effectiveness of the antimicrobial elements of this filament, as I have no way of proving it myself. It prints just like any standard PLA, same temps worked for me. Came nicely packaged and dry. I wish it were cheaper and more readily available, I’d likely print more using this material.

I got one of the last spools of Plactive available for civilians or non-hospital sales. Lucky lucky. I used it all up making three hole punch face shield frames. I had ZERO problems printing. And I had LOTS of nurses and technicians saying thank you and even more that I'll never hear from. Thank you for allowing me to order this back in late March. My father and I printed a whole bunch of shield frames. I hope to work with the Medflex soft rubber filament soon.

I used to print some MASK for the MASK_Project for COVID-19 but material is too hard and some parts are difficult to assembly togethermaybe for hard forms is good.

Copper PLA works excellently. I have not had any extrusion or layering issues with it. I ordered this in order 3R print COVID masks for my friends and family. Due to its copper material attributes it is antimicrobial.

Easy to work with! We used it to make masks at the beginning of the covid-19 outbreak

Great customer service. Came exactly as described.

Fun to work with!
