Bring the dimensions into the conversation early
A larger shape needs an early discussion of its overall size, orientation and purpose. Provide all three dimensions, not only the longest one. Include any features that restrict how the part can be positioned or assembled.
Check the shape as well as the size
The overall dimensions are one part of the decision. Orientation, supports, material and surfaces that need to remain continuous also affect how a larger part can be made.
Discuss the actual geometry before assuming a part can be printed in one piece. Suitability and the proposed approach need to be agreed for the particular design.
What to include
- Overall dimensions and the part’s intended use.
- Features that must line up with another object.
- Whether the finished appearance or a continuous surface is important.
- Quantity and the timing you would like to discuss.
Possible changes to orientation, shape or assembly need to be considered against the actual design. Do not assume that joining or splitting a model is included by default. CAD assistance can be scoped separately when a design change is needed.
