1.4 Challenges for Teachers
While 3D printers can be beneficial classroom tools, they are not without their challenges. Here are the most common concerns that educators have about 3D printing and answers to help you out:
“I can’t afford a 3D printer.“ Look for small grants ($500-$1,000) from local organizations, the PTA, or even local companies to purchase a 3D printer. Here are some resources to help you get started:

“I don’t have time to write grants or learn how to use a 3D printer.“ Don’t worry, there are alternatives to owning a 3D printer:
- You can have your students design digital 3D models for free using tools like Tinkercad and get many of the same benefits, such as 3D modeling skills, creative thinking and problem solving skills, and technological literacy development (see the Designing 3D Models section of this module).
- Check with your local library and school district to see if anyone has a 3D printer that you could borrow or print models.
- Explore these professional 3D printing services to print out 3D models.
“I don’t know how to teach 3D modeling skills.”
- Students can go through tutorials on YouTube or on the 3D modeling platform (e.g., Tinkercad Learn) to teach themselves the necessary skills to create 3D models. You can also partner with your school art or technology specialist for additional support.
- Before jumping into 3D modeling online, we recommend encouraging students to sketch their 3D object from multiple perspectives and design a physical 3D model in a low-tech makerspace, using Legos, Perler beads, PlayDoh, construction paper, and other hands-on materials.
- Students should write the step-by-step design process down, so that when they move to the 3D digital modeling environment, they can recreate the steps with ease.
“I don’t see a need for fancy new technology in my class.” Afraid of change? I feel you! Change is difficult for everyone, but as a teacher, remember that you are preparing your students for the jobs of the future. Our students grow up in digital communities. The best way to teach and reach them is to make a real world connection. 3D technologies will not only make teaching relatable, but also help students develop valuable knowledge and skills for future careers.
If you are worried you may not know how to problem solve or fix 3D printing issues, turn the task over to your students – they’d be happy to become the 3D printing experts. You can provide the support and encouragement!
