It will happen using carbon nanotubes. They turn out to be much better that carbon fibers. Also, like the other guy said, some surfaces will have to have steel surfaces inserted for cylinder liners, bearing journals, etc.
>>14200398 as said it's the resin that matters. no doubt they could make one that works but why bother? the resources needed to actually manufacture the blocks would be huge. composite blocks have been around for years, only the metal ones actually made production Honda FRM and Toyota MMC that I can think of, and F1 pistons too.
>>14200398 I'm shocked at how quickly 3D printing became a meme. Thank God printers are still expensive, so that every 15 year old can't spam their Twitter with garbage they downloaded off of Makerbot.com and printed, while acting like they're Adam Savage, Mark Zuckerburg, and Elon Musck rolled into one person.
"Very high performance epoxy laminating and casting resin designed for use in high temperature environments up to 180°C (356°F). This resins HDT (Heat Distortion Temperature) of 180°C means that up to this temperature the epoxy will not shrink, crack or distort..
As well as its high HDT this epoxy system also has good clarity, a low viscosity and exceptional wetting characteristics when used with carbon fibre or aramid fibre (i.e. Kevlar). When cured the resin has excellent mechanical properties. "
Why? It would be heavier than aluminum by the time all was said and done. Proportionally, engine blocks are basically the minimum size to accommodate all the necessary systems like cooling, oil, and then all the actual mechanical parts of the engine. Making it out of carbon fiber would result in the same volume but heavier since carbon fiber is on average heavier than aluminum.
This is not even bringing up the ACTUAL issue of carbon fiber not being hyperutectic. It's way too unstable to be a good block.
>>14200886 OK professor, reduce a corvettes,or 911, weight by ~10% then reduce it by another 10% ,make it cheap, stop fucking children,then reduce it by another 10%. Just because weight has been reduced doesn't mean it can happen over and over again,stupid.
most engine related automotive stuff is limited by the plastics right now, but there are plenty of other non engine components you can make from ABS.
Quit watching Barnacles Nerdgasm and similiar autistic people. Literally all they do all day is print dildo's and other useless shit they found on thingiverse.
The reason nobody does anything interesting with it is because for the most part, nobody has the ability to create models easily. I am in college so I have access to Solidworks but not everybody has that.
Printers aren't expensive either by the way. I built a Prusa i3 for around $350.
