We do it on 3 levels:
1st level - 3D model.
The design of the 3D model is the most crucial aspect of 3D printing. Even not-so-skilled maker can 3D print a quality product if the model is fully optimized. SWe validate and test print every model that goes on Vulkaza to make sure that the end result will satisfy you.
2nd level - maker skills.
All makers who want to start 3D printing with Vulkaza have to prove their skills either through examples of previous work or 3D printing our special model. We only work with experienced makers with 3 to 5 printers and at least 2 years experience.
3rd level - product inspection.
After 3D printing the model, makers take pictures of the final product and upload them via the maker's app. We closly inspect all orders and allow shipping only after the quality has been checked. Not that we don't trust our makers. We're all human beings and have different understanding of quality so this step also allows us to give feedback and improve maker's skills.
