Parts shipped in an instant and the quality of the product was as expected. Even got at hand written thank you note and I will definitely return to this vendor later.

Fast fulfillment! Ordered a hotend assembly for my Robo 3d R1+. It came within 3 days. Part worked perfect right out of the box. I would definitely order from them again if I need more replacement parts for my 3d printer.

Needed parts for my Robo3D R2 First order was in stock and shipped immediately. Second purchase was out of stock... notified me when the part was back in stock and shipped immediately. Great company to work with!

What everyone else has said times 10! The best over all service I have had in a long while!!!!

I ordered some water soluble filament which didn't work for me and Partsbuilt 3D refunded me with no problems. Good company to deal with, I will go there again when the time comes.

Five star service! Needed parts for my Robo3D R2 printer and found them here at an affordable price. Quick order turn around and follow up communication. Highly recommend.

This company is so refreshing, it is unusual now days for a firm to give such special attention to your needs. They are extremely fast on filling orders, great prices and great follow thru. Being new at 3d printing, I have ask Jonah questions and he has always responded very promptly. With their attention to detail, this company will go far. They will certainly get my business.

This is my new go-to place for Robo 3D parts. They shipped so quickly I was back up in 3 days. Now all I need is parts for my Duplicator 4s.
