A 3D printer is a machine that builds physical objects from digital files that contain 3D information. Using a process sometimes referred to as "additive manufacturing," a printer typically constructs the object by bonding layers of material together one layer at a time.
While there are several different types of 3D printers, most hobby-level models use a method called fused deposition modeling (FDM) to extrude, deposit, and fuse the layers together.
Studio 411 has three Bambu Lab P1P FDM printers.
3D printers need files containing 3D information to make objects. You can create a file from scratch or download a file from an online repository.
Before printing, the file containing your 3D model is imported into a piece of software called a slicer - we use Bambu Studio in Studio 411. A slicer divides the design into multiple layers defined by customizable settings. It generates a 3D preview of what your object should look like once it is extruded, which can help you identify flaws in your design. Once all settings are confirmed, the slicer writes a new file containing instructions for the printer to follow. The new file is uploaded to the 3D printer, and the print starts soon after.
An FDM printer is typically loaded with colored plastic that is wound on a spool. The plastic is pulled off the spool and through the machine with gears before being exposed to a heat source. The heated plastic is extruded from a moving metal nozzle and deposited onto a platform where it hardens. The printer works from the bottom to the top of your design, adding layer upon layer until your project is complete. All prints made with an FDM printer will have visible layer lines.

Many designers add their models to online repositories, often making some designs available for free. Here are some sites where you can see what others are making or download files to print:
Free modeling software is available for all skill levels. Here are a few web-based options to get you started:
Tinkercad - If you're new to modeling, this is the best place to start! Easy and fun, combine and subtract simple forms to create your first design.
SculptGL - Free 3D sculpting that doesn't require an account. Create organic shapes by manipulating a digital ball of clay.
Onshape - CAD (computer-aided design) program better suited for product design. Powerful enough for industry professionals, beginners can pick up skills with their self-paced courses.
Parents, guardians, and caretakers are welcome to submit prints on behalf of their children who are under 18, limited to one active file in the print queue per child. Child must have a linked library card to qualify. Studio 411 staff will only correspond with adults.
Please note that 3D print requests will be attended to in the order they are received, and we cannot schedule a viewing time for your child to see their object being printed.
All 3D printers are entirely staff-operated, and 3D printing is a service offered exclusively to Helen Plum Library cardholders. No machine reservations are required, but patrons must submit an online request to participate.
Submit your request by filling out our 3D Print Request Form.
We cannot arrange to print an object at a specific time for you to observe.
At this time, all prints are free.
We anticipate charging for prints in the future, but we will give ample notice before we switch to a paid model.
We use standard 1.75mm PLA exclusively. We cannot print with external filaments provided by patrons.
PLA stands for polylactic acid and is a type of thermoplastic typically made from corn starch. It is one of the safest forms of plastic but is porous and has a low melting point.
PLA is not recommended for objects that will come in contact with food/drink or be exposed to high heat.
We accept STL and OBJ files.
Once we receive your print request, staff will review your file (typically within 3 business days) to ensure that it follows our guidelines and is printable. If your print is approved, you will receive an email with a print estimate we'll ask you to review. Once you respond to that email to finalize your print request, we will add you to our print queue, which is first come, first served.
Your 3D file will be deleted once your print is finished, and we will not be held responsible for loss of digital property.
A 2-week turnaround is typical but not guaranteed. Turnaround time may be affected by the number of active requests, staff availability, machine maintenance, and library programming needs. We cannot guarantee that a print will be available by a specific date.
Once your print is completed, we will notify you via email that it is available for pick-up from the Adult Services desk.
Prints that are not claimed within 2 weeks will become library property. You will be responsible for another print request if you would like the object reprinted. Your new order will go to the bottom of the print queue once it is confirmed.
Helen Plum Library cardholders are allowed one active print request in our print queue. Multiple submissions will be ignored, and files will not be retained for future requests. You are welcome to submit another print request as soon your last object has been picked up.
Our print request form only allows one file attachment per request. If you would like multiple items printed on the build plate, everything must be present in the submitted file.
We can only print your project in a single color - all objects will be the same color.
If you are interested in printing in a specific color, please list your preference in your print request form. While Staff will do their best to respect color preferences, colors are subject to availability and your choice is not guaranteed.
Unless specified, most prints will be made with the Standard 0.2mm Bambu Studio preset with 15% infill and 2 walls.
Supports will be added to pieces with significant overhang, and brims will be added when objects have small build plate contact points. Both settings will add to your overall print time.
If you are interested in specific settings, please include the details in your print request form. Staff will do their best to accommodate your preferences but reserve the right to reject a request on any basis.
STEP files containing modified settings will not be accepted.
Staff will not be held responsible for failed prints.
We currently cannot provide design consultation sessions or 1-on-1 assistance. If you have questions, please email studio411@helenplum.org, and we may have suggestions.
Staff may not be able to offer guidance on more advanced topics.
In submitting a request form, Studio 411 users have agreed not to request 3D prints containing copyrighted content. Staff reserve the right to refuse any prints that violate the user agreement.
Miniatures have fine and fragile details that will likely break off, distort, or get stuck in support material. While we do not recommend submitting requests for miniatures, if your print request follows all guidelines, we will attempt to print your file.
If your print fails, you will be notified, and we will move on to the next request.
No. While resin printing is an increasingly popular manufacturing process across DIY communities, it requires a level of ventilation that is not possible within our makerspace.
Patrons are responsible for removing their own raft, brim, and support material. Tools and safety equipment will be available for in-studio cleanup, which Staff will reach out to schedule.
3D printing is a publicly visible service. It is likely that other patrons will see what we're printing for you, but staff will only discuss your submissions with you.
While the Library cannot guarantee design confidentiality, none of your digital property will be intentionally shared or retained; your files will be permanently deleted once your request is complete.
