3D Printing

I’m doing two 50 min speaker sessions about 3D printing and using the technology this Saturday. So far I am covering the following:

-Early uses/80’s printers
-Emergence of the RepRap movement/benefits of open source
-Main types of printer machines (SLA/DLP, SLS, and FDM) and their benefits/downfalls
-Industrial examples of the tech in action.
-Rundown of my Reprap designs with brief demonstration on the Play
-Talk briefly about what to think about when designing for printing (overhangs, heat dissipation, tolerances, and ringing suppression/rounding)
-Q/A

Can anyone think of some big topic that I am missing/should cover. I ideally want to be able to talk for at least 30 of the 50 minutes but would rather push it a little past that if possible.

Control electronics.

It might be worth covering some of the practical problems that all beginners face, like getting the first layer to stick, and the various underlying reasons like uneven build plates etc, plus common strategies employed to solve those problems, for example; glues and heat and tape etc.

Just an idea…

4

Slicers?

5

Types of filiment/resins used and their pros and cons

6

Know your printer and its abilities and limitations. Know your print material and its abilities and limitations. Design accordingly.

Thanks guys! I really appreciate the feedback. Materials is being covered for sure and now beginner’s issues. @Jeff_Parish design is a big part portion now! Thank you for the input!

8

Material types, post print finishing, examples of how 3d printing will change how things are manufactured ( one off parts, replacement parts that aren’t typically available, prosthetic devices for low cost, etc…)

9

Non standard uses of 3d printing… like the 3d printed concrete structures , pottery, food
