A lot of objects broke during shipping or before. Some of the communication was not clear and could have made the process easier. Otherwise quality products.
回复: As we explained at the start of the project, these designs were clearly made by children with little/no prior experience with 3D modeling for manufacturing. Many of the files had multiple "bodies", arranged as scenes in design software rather than modeled with respect to each other. Some contained dozens of bodies, including some too thin for slicer software to recognize (finer than the 3D printing resolution). We printed what we could and also explained mid-way that the students' surprise over disjointed and surprisingly small, thin, or large parts could serve as a teaching points about using DIMENSIONS and basing each step of designing on previous steps. No parts were broken when we shipped the order, but I imagine the broken ones were the abnormally thin pieces... I hope the students appreciate the results and grow as engineers from them! Another lesson is how quickly designs can be iterated with 3D printing. Thank you for the patience with the large and tedious order.
