Hello! Very impressive project. Congratulations.
It would be nice to have a confrontation with a 1/10 printed at home and a 1/10 on the market to see how much difference there is still (materials, durability, driveability, times, etc …).
I would like to perceive how much real difference there is more.
According to you, how many years are required to be able to print cars like the current ones on the market?
Sorry for my english!
i dont think it would be a fair comparison, especially regarding time, materials and price. of course would be usually much cheaper if you buy it of the shelf and it would also take less time to put it together, let alone the durability (for the most parts), but that’s not the point here.
Regarding the OpenRC Truggy, there is no need to slap a price on it or compare it to any commercial product at all. Its simply a hobby where not the ready to roll car is in focus but the way how to make it, utilizing a 3D-printer and customizing it on the go as you see fit. driving it when its ready will be fun too, but for me most of the fun is building it in the first place.
And i’m not looking at the costs and time here, the longer it takes the better for me in this case…
Totally agree with you. I wanted only focus the discussion on the near future when it will be possible print objects in a very fine way at home. And in that moment i think there will be a really big revolution.
the future is now 
Makerbot just announced three new printers, but they are focussing on PLA only. In my opinion thats to narrow. PLA has some nice features but its not even as durable as ABS (or other materials for that matter).
But in any case with FDM you’ll aways have to compromize. But thats what you can get affordable at home at the moment.
If you need more durability/stability there is still the possibility to get a CNC. For hobbyists there are as affordable as 3D-printers. Than you can combine both …
