+ | =====Additive Manufacturing===== | ||
+ | Our interest in 3D printing is initially for the production of plasma diagnostics at much reduced cost. However, the technology is maturing, and so the application of the techniques to a wider range of subsystems that are relevant to fusion energy development could potentially impact costs for fusion energy itself. | ||

+ | ==Using inkjet printers:== | ||
+ | |||
+ | given that we have about 6 circuits to prototype in this contract, and | ||
+ | the mandate is go after AM technology, am starting to think through the | ||
+ | use of AM circuit printing. The technology is not very mature, so there | ||
+ | might be opportunities here. What I can glean is that the technology | ||
+ | has three main thrusts: | ||
+ | |||
+ | 1. 2D printing with inkjet deposition of silver nitrate and ascorbic | ||
+ | acid leaving tracks of silver (e.g. | ||
+ | [[http:// | ||
+ | |||
+ | 2. 3D printing components and extruding conductive materials into the | ||
+ | build with 2nd head (e.g. [[http:// | ||
+ | |||
+ | 3. 3D printing circuit boards and using conductive paint on the | ||
+ | underside (e.g. | ||
+ | [[http:// | ||
+ | |||
+ | ____________pros and cons: | ||
+ | |||
+ | 1. 2D Inkjet | ||
+ | pros: track size OK for ICs, print on any substrate, tracks smallest | ||
+ | printing on standard circuit substrates | ||
+ | cons: silver layers are 5x more resistive than copper tracks, unproven | ||
+ | cost: 2000 for the 1st generation printer | ||
+ | |||
+ | 2. 3D Extrusion | ||
+ | pros: can to mechanical and electrical simultaneously | ||
+ | cons: track sizes still too large for ICs | ||
+ | cost: $350 for the head | ||
+ | |||
+ | 3. Extrusion then post-process | ||
+ | pros: simple to do | ||
+ | cons: no automation, can't send a kicad or gerber file to be printed, | ||
+ | looks too amateur. | ||

+ | ====Printing Tips==== | ||
+ | |||
+ | 3mm filament is easier to print with (than 1.75mm): more rigid, cheaper, faster prints, fewer tangles (Note, our machine only takes 1.75mm anyway) | ||
