3D Printing

Dropbear has been designed with a modular structure, making heavy use of 3D-printed parts that can be printed on a 30 x 30 x 30 cm printer bed.

Total 3D Printable Parts (approx)

• Head: 10 parts

• Arm: 22 parts (per arm)

• Torso: 26 parts

• Pelvis: 18 parts

• Leg: 36 parts (per leg)

You can either print the parts in-house using your own 3D printers (we recommend Bambulab P1S) or use a external service to get them manufactured.

All the 3D models and printable files are available here: Dropbear 3D Printable Parts. For Bambu Labs printers, pre-prepared printer plates can be downloaded here <> for efficient printing.

Infill, Tolerances, and Adjustments

• Infill Values: For each part, we have defined the optimal infill value in our sliced plates which are ready to be loaded into your 3D printer for starting printing parts. But, depending on the part, you might need to make some adjustments. We recommend using 20-40% infill. For load-bearing components, a higher infill value can provide added strength.

• Tolerances: Ensure you're using appropriate tolerances, especially in areas that involve fasteners or joint movements. You may need to fine-tune the dimensions if your 3D printer has varying precision or if you’re using different types of fasteners.

• Tweaks and Adjustments: Given that different printers and materials have their quirks, you may need to tweak some dimensions or tolerances, especially in areas that experience high stress or friction. It’s important to keep testing and refining for optimal fit and function.

Customizing the Design

If needed, feel free to adjust the CAD designs. You can access the STEP files here: Dropbear STEP Files. These are fully editable, allowing you to customize the parts based on your specific needs or improvements you wish to make.
