Standard vs. Production Quality

Sometimes fast & cheap isn't the best option
Sometimes fast & cheap isn't the best option
Sometimes it needs to be good!
We offer upgrades in quality to what we refer to in the industry as Production Quality and we've narrowed it into two categories to streamline the experience for our customers - Form or Function. Based on the application and intended use of the parts produced, we can tailor quality towards cosmetic improvement or towards functional improvement.

If > 3 minor defects OR > 1 major defect OR ANY critical defects exist, the part will be scrapped
Larger parts may get sent for approval if they are common due to order complexity or if we find elevated rates of failure during production.
If ANY major defect OR ANY critical defects exist or >1 minor cosmetic defect, the part will be scrapped
It is assumed there will be higher scrap rates due to lower tolerances for minor defects

Frequently Asked Questions
Frequently Asked Questions
IS THE LEVEL OF QUALITY CUSTOMIZABLE?
Yes!In fact, you can prioritize different levels/types of quality requirements per line item/model.
If one part needs to have high cosmetic quality because it is outward facing, you should tell us that!
If another needs to have a specific fitment requirement inside another part but it doesn't really matter how it looks, you should also tell us that!
And if standard quality is just fine for others, that's ok too!
We always try our best to accommodate our customers' needs
WHAT IS A DEAL-BREAKER?
A deadlock, an impasse, and irreconcilable obstacleCOMMUNICATION IS KEY!
We ALWAYS need to know these before starting an order where quality is a concern. Unfortunately, we haven't mastered the art of mind-reading, so we really need you to lay it out for us like we are small children so that we can ensure you have the best possible experience working with us.
Examples:
Part A must fit a certain way with Part B otherwise both become useless
Specific minor defects render a part unusable or unsuitable for it's purpose
CAN YOU REALLY OPTIMIZE FORM & FUNCTION?
It depends...We try to determine whether a part can be optimized for better form or function that what we consider "normal" for ODM FDM 3D printing. If normal is perfection, absolutely! We won't charge extra if our normal is your perfection.
If perfection or near perfection is not achievable for a part, we always strive to be up front about that with our customers.
