3D printing has become a popular method of creating large-scale models, prototypes, and even finished products. However, when it comes to 3D printing large objects, the process can be a bit more challenging than printing smaller items. Here are some tips to help you successfully print large objects on your 3D printer.

  1. Choose the right 3D printer: Not all 3D printers are created equal. Some printers have larger build volumes than others, which is crucial when printing large objects. Make sure to select a printer that is capable of handling the large print size you need.
  2. Use a larger build volume: Some 3D printers come with larger build volumes that allow for bigger print sizes. If you’re looking to print large objects, it’s important to consider a printer with a larger build volume.
  3. Use a larger nozzle size: A larger nozzle size will allow for faster printing and can help decrease the overall print time. This can be especially helpful when printing large objects that take a long time to complete. This can reduce the print quality as the print layers are more pronounced.
  4. Use a high-resolution printer: High-resolution 3D printers can produce more detailed and accurate large prints. This can be especially important when printing large objects that will be used for display or as finished products.
  5. Use a high-quality filament: Using a high-quality filament will result in a better finished product with fewer defects. This is important when printing large objects, as any defects will be more noticeable on a larger scale.
  6. Reduce the number of internal supports: Large prints require a lot of support material, reducing the number of internal supports can help to decrease the print time.
  7. Make sure to level the bed: A properly leveled bed is crucial for large prints to ensure proper adhesion.
  8. Use a raft: A raft can help improve the first layer adhesion and also will help to prevent warping.
  9. Model Slicing: Slicing the model in the right orientation is critical to ensure the print is strong.
  10. Be patient: Large prints take a long time to complete and require a lot of attention, so be prepared to spend a significant amount of time monitoring the print and making adjustments as needed.

By following these tips, you’ll be well on your way to successfully printing large objects on your 3D printer. Remember to be patient, take your time and to not hesitate to reach out to the 3D printing community for help and advice. With the right knowledge and tools, you’ll be able to create large-scale models, prototypes, and finished products that are both impressive and accurate.

I recently printed a 1.5-meter T-Rex skeleton (source: T-Rex Skeleton by MakerBot – Thingiverse) using glow-in-the-dark PLA material for my kids’ room. The tail did detach due to its weight, I am working on a solution to prevent this occurring again.
