Exceptional prototyping at competitive price

My experience with 3erp has been nothing but exceptional. From the start the communication has even accurate and fast. Specificities of the design that may meet production difficulties are promptly pointed out with suggested solutions. The price of prototyping is competitive. And the QC of the final product is also excellent. There is no doubt that I will go back again

Our No.1 source for CNC parts

Even for a complex 5 axis CNC part we got very good results from 3ERP. We did a lot of projects with 3ERP during the last 3 years and they always did an outstanding job - high quality (I can also recommend their laser logo service and anodizing), reliable, extremely fast and perfect communication. I highly appreciate working with Ronan and Victor and already recommended them to many of our partners.

Reliable company, outstanding in precision work.

It's very nice that you can make complex miniature prototypes down to the smallest details and with also a high precision. For us, this quality is necessary to do reliable tests. Great that you can meet these high requirements. Good work, keep it up!
Stay affordable and we hope to continue working with you for a long time.

Using 3ERP for many years now

Using 3ERP for many years now. Always quick, always efficient, always reliable. If something's wrong they redo the parts without any drama. Compared to most European CNC providers, 3ERP's customer service is head and shoulders above. Highly recommended if you request any CNC machined parts to verify your new design.

Very satisfied client of 3ERP

3ERP have been exceptional to deal with. Being in Australia I did predict some issues with correspondence and possibly result but I was WRONG. It has been so easy dealing with the guys from 3ERP from the other side of the world. The result of the products have been amazing, we had a small issues at one stage but it was quickly addressed and you cant ask for much more then that! I highly recommend giving them a go.
