What do you do if your coworker's 3D printed design needs improvement?

1 Offer Help

Approaching your coworker with an offer to help can be a great icebreaker. Frame the conversation around collaboration rather than criticism. You might say, "I've noticed some aspects of the design that could be enhanced for better printability. Would you like to go over it together?" This opens the door for a constructive dialogue and positions you as a supportive colleague, not a critic.

2 Be Specific

When discussing the design, be as specific as possible about what you think needs improvement. General comments can be unhelpful and even frustrating. Instead, focus on particular elements, such as wall thickness, support structures, or the orientation of the print on the build plate. This specificity will show that you've paid attention to the design and have practical suggestions for enhancement.

3 Share Experience

Sharing your own experiences with 3D printing can make your feedback more relatable. Talk about similar challenges you've faced and how you overcame them. For instance, you could share how adjusting the infill density improved your print's structural integrity. This not only provides actionable advice but also creates a sense of camaraderie.

5 Encourage Testing

Encourage your coworker to test their design through rapid prototyping. Small iterations and test prints can reveal issues that aren't apparent in the CAD model. Advise them to adjust one variable at a time and keep track of the changes. This methodical approach can lead to significant improvements without overwhelming them with modifications.

6 Follow Up

After offering your feedback, make sure to follow up with your coworker. Ask if they found your suggestions helpful and if they've made any progress. This shows that you're genuinely interested in their work and are willing to continue supporting them. It also provides an opportunity for further discussion and learning.
