Switching to injection molding for manufacturing frames could offer several advantages for scaling up your business. Here are some key points to consider when comparing injection molding to 3D printing:

- Production volume: Injection molding can produce a higher number of frames in a shorter time than 3D printing. This is essential when scaling up your business to meet increasing demand.
- Material options: Injection molding allows you to use a broader range of materials, including different plastics and composites, to suit various design and performance requirements. This could potentially enhance your product offerings.
- Cost efficiency: Although the initial investment for injection molding equipment and molds may be higher, the per-unit production cost is typically lower, making it more cost-effective for large-scale manufacturing.
- Quality and consistency: Injection molding can produce parts with more consistent quality, which is crucial for meeting industry standards and ensuring customer satisfaction.

However, there are some design constraints to consider when using injection molding compared to 3D printing:

- Mold design: You'll need to invest in designing and manufacturing molds for injection molding. These molds need to be precisely made to ensure the proper fit and function of the frames.
- Undercuts and complex geometries: Injection molding may struggle with producing frames with complex geometries or undercuts, whereas 3D printing allows for more design freedom. You might need to modify your frame designs to accommodate the limitations of injection molding.
- Parting lines and draft angles: To facilitate the ejection of parts from the mold, you'll need to incorporate draft angles and consider parting lines in your design. This might require adjustments to the aesthetics or functionality of your frames.
- Lead time: Switching to injection molding may increase your lead time, as you'll need to design, manufacture, and test molds before starting production.
- Mold maintenance: Molds require regular maintenance and replacement after a certain number of cycles. When considering injection molding, you'll need to factor in the costs and time associated with mold maintenance.
