3D Hubs is the most autonomous Manufacturing platform out there. We've built great manufacturability tools into our 3D File viewer to predict any manufacturing issues with your specific design. This feedback will help you decide which technology to use and how to adjust your file in case of an error.
Our Manufacturability analysis will either indicate which technology is best for your project, or which part(s) of your model need improving in order for you to get the best outcome for your design and to proceed with the order.
Detecting design errors as soon as possible is vital, in order for us to keep the production process as seamless as possible. If you believe we're falsely preventing you from placing the order, please do not hesitate to contact us through firstname.lastname@example.org'
The 3D Hubs portal is interpreting every file as if it is exported in millimeters. Exporting it in your software with different settings would cause the 3D Hubs to misinterpret the size of your file.
A feature to toggle between the exported dimensions is coming out soon.
Generally 3D printed models over 128 MB consist of millions of polygons, which often means the design contains polygons that usually have no influence of the 3D printed end-result (unless your 3D model is highly detailed, like for example a character model that shows every wrinkle and pore). Hard surface designs generally do not surpass 50.000 polygons, which is far below the 128 MB file-size.
The CAD Files (such as .STEP or .IGES or similar) generally should never exceed this size limit if they include a single part. Assembly files are generally not accepted, so please make sure to upload all the parts as separate CAD files.
For 3D printing, orienting your parts differently can make a specific side of your model look cleaner or achieve better suited mechanical properties for your application.
3D Hubs offers a tool to indicate the ‘cosmetic’ side of your model, which you want to remain untouched with support material. This information will be sent to the supplier and they will do their best to avoid any production marks on the indicated part of the model.
For now, this feature is only available for SLA (Resin) orders.
