Cranberry Public Library Makerspace Hosts Accessible Tinkercad 3D Printing Classes

Local makers packed into the Cranberry Public Library’s Forge Makerspace to learn basic 3D design and printing skills at a community class on Jan 17, 2026. The hands-on sessions guided participants through Tinkercad modeling, converting designs into STL files, and the slicing steps needed to get parts from screen to print bed, giving attendees a full end-to-end sense of the workflow.

Volunteer instructors and local engineers led the classes, demonstrating how simple geometry can become usable objects such as toys, tools and fixtures. The classes were open to a wide age range, drawing teens interested in design, parents exploring STEM activities with kids, and adults looking to prototype household fixes. Instructors emphasized practical projects and quick wins so learners could test prints by the end of the session and iterate on design and printer settings.

Organizers framed the workshop as part of ongoing makerspace programming that mixes free and fee-based offerings throughout the year. The Forge Makerspace provides an entry point for people who do not own a printer or lack software experience, reducing common barriers to getting started with additive manufacturing. Volunteers noted that current consumer 3D printers and beginner-friendly CAD tools like Tinkercad make it easier to move from an idea to a printable STL than it was even a few years ago, helping more community members try prototyping without a steep learning curve.

For practical value, the classes covered essential tasks that translate directly to home and hobby projects: creating watertight models, exporting STL files, choosing slicing parameters such as layer height and infill, and preparing the printer for a reliable first layer. That combination of modeling and slicing is aimed at keeping the feedback loop short so learners can diagnose common issues like bed adhesion and stringing during subsequent prints.

The makerspace’s role as a community resource was clear: it serves as a place to learn, test tools and meet local engineers who volunteer expertise. By lowering technical barriers and offering regular programming, the library helps residents move from curiosity to capability in 3D printing. Expect more beginner-friendly workshops and deeper skill sessions in the months ahead, and bring a simple project idea if you want to turn a quick sketch into a shelf-ready print.
