3D printing refers to rapid prototyping - creating a physical 3-dimensional object from a digital model. There are several types of 3D printers. The printers that we use are the Printrbot Play and Prusa i3 MK2, which perform a Fused Filament Fabrication technique (also known as Fused Deposition Modeling - FDM) to create the final 3d printed object. In this method, a lightweight plastic filament that when fed through the nozzle is heated up to its melting point and then extruded onto a build plate surface, hardening upon impact. This process continues, depositing the melted filament layer by layer until a 3-dimensional object is formed.
3D prints can be found useful in numerous applications, such as prototypes for entrepreneurs, architectural models for class projects and for any other low-volume, custom-prototype needs. Here are some examples of practice use in an educational environment:
The 3D printing service is open to all currently enrolled Kent State students in all disciplines. The actual printing process is performed by our SMS consultants. Have a class of students who wish to 3D print? Contact us first to discuss the assignment so that we can review our policies with you and discuss any limitations that you may have in printing.
The maximum build volume that we prefer is 250 (X) x 210 (Y) x 200 (Z) mm. However, since the printers only run while we are open, the total printing time for a particular model must be under 12 hours, which for a cube-shaped model would equate to a 94 x 94 x 94mm design.
Please be aware that we may ask to print your model at a smaller scale than you would like. We do this with the goal of ensuring the best success of your print. With creative design, though, you can print larger simply by separating your model into smaller printable pieces. So keep that in mind as you prepare your file for printing.
We do not have any limitations in the modeling software that you use. We have two file formats that we accept (STL and OBJ) and as long as your software can save or export as one of those formats we should be able to print your model.
We accept STL and OBJ files. Most 3D modeling programs can save/export as at least one of those two. Please note, if creating a model in Tinkercad please download your design as an STL file (not an OBJ). For some reason we have difficulty opening OBJ files that have been produced in Tinkercad.
