Want to buy an advanced 3d printer but unsure if your specific design in your filament of choice will be 3d printed to the required level for the 3d printer you are considering? Then this test 3d print service is for you. We'll offer you some free advice on the part's design, known challenges, & what to expect for your desired filament & 3d printer. You send us the stl file & your brand of filament, & we will 3d print it using that advanced material on the 3d printer you wish to evaluate. Common ultra performance materials include PEI Ultem, PSU, PPS, PPSF, PPSU, PPE-PS, PEEK, PEAK, PP & Even experimental filaments that may not be mass produced yet. The same is also available for liquid resins. So if you want to check if a batch of different parts can be printed, we can do that for you on the resin 3d printer you would want to buy. Please contact us before buying this service, & please only purchase it after we have confirmed for you to do so.
