such as bad edges, holes, and reversed normals.
Designing your model for printing
The first step in printing your idea is to design the 3D object using a computer-aided design (CAD) software program. There are
numerous open source and free software options to render your digital model including Blender, OpenSCAD, and Sketchup. A more
complete listing of these options can be found on the Morris Library 3D printing web page. Users will need to submit their file in .STL file
format in order for library staff to convert the file to one that the Makerbot Replicator 2 will read.
If you do not wish to design your own 3D object, there are sources to find models already designed that you may print or alter and then
print. Two of these resources are Thingiverse and Yeggi.
File approval
Users must submit their files in .STL format. Users will need to fill out and submit the 3D Printing Request Form along with their .STL
file. Library staff will review the file and send a confirmation email to the address provided that the submission has been received. The
email will state whether the file has been approved and any important information for the user. Library staff may need additional
information about the print job or may need to schedule a consultation with the user. Once the file has been printed, staff will send
another email informing the user of the cost of the print and the due date to pick up the model.
If you have several files to print, please submit each of these separately by filling out a separate 3D Printing Request Form for each
print.
All submissions are subject to approval based on scheduling and availability. There may be times that the printer is malfunctioning,
being repaired, or is being used for an event or a course. During such times, the 3D printer may be unavailable for use and there will be
a delay in approving submissions and printing objects. Any significant lapses in printing time will be noted on the 3D printing web page.
After the submission has been printed and the print has been picked up or the two week time limit to pick up the object is over, the
submitted file will be deleted by library staff.
If a user wishes to print their object themselves, they will need to schedule an appointment with library staff to receive training on the
3D printer. Users will be supervised by a library staff member during the printing process. The submission form will include this option
and a library staff member will contact the user to schedule a training session.
Quality
Users may see slight imperfections in their prints. Small bumps or holes and rough edges at the base of an object may occur with 3D
printing. You can clean up some of the imperfections with fine sand paper or other tools. The Makerbot Replicator 2 is very accurate,
but there may be some instances where objects do not fit precisely together.
The Makerbot Replicator 2 builds objects from the ground up. There are instances where certain prints will require support material and
/or rafts to ensure proper printing. Support material is often needed if the design has large overhangs or parts suspended in mid-air.
Rafts are often used as support at the base of the model. These types of additions are easily removable by the user. Staff will not be
responsible for removing any supporting material and /or rafts for the user.
Contact
If you would like to meet with a library staff member for additional information about 3D printing or if you have questions, please email
