Topic: do you have a 3d printer ? - page 2. (Read 1468 times)
thanks will pm you when i get a min
I can do the cad for you if you send me all the dimensions/pictures. I like doing this stuff and I'm currently on a co-op for designing automotive parts in CATIA. I will be able to provide you with a STP or STEP file, which any 3d printer or cnc machinist would be able to open.
Though I will tell you, I've had experience printing gears on a 3d printer(used a $17000 printer at my school) and if they're too small they just will not work at all without a pro who knows what they're doing. The teeth look bigger than what I was doing though.
Gears are not cheap. Let me know what you want to do. It would probably take me <1 hour to get you a cad file. As long as the tooth profile isn't overly complicated.

i will have a look in the morning and get good picks and dimentions ( 2.31am here )
i took it to a shop and they wanted
10000gbp for them to make an injection mold and make 100 of them and thy keep the mold
or
1500gbp for 10 made out of aluminuim still cheaper than buying the over priced plastic ones
any cheaper altenatives ? its no more than 15mm x 15mm i would be willing to send out one of the plastic ones so somone could get mesuremnts from it

You'll need it drafted if it is to print. Teeth will be difficult if it's particularly small depending on the resolution of the printer. You may need something specialized to handle small parts. Something with 1/16th stepping enabled, and with a much smaller diameter print nozzle. There are generally two different plastic types to work with. You'll probably want ABS, but it will be difficult to shape the gear out of it depending on how small it is.
So, the parameters are thus: Ensure a heat-bed is used, add some cooling (but not too much) for the gear teeth, make sure that the highest resolution possible is used (a stepper-motor driver capable of 1/16th microsteps) as well as a small print nozzle. But drafting the part will be the most difficult.

thanks i have been looking for good info its anoying they stoped making the part over 4 years ago and people that are seling it are looking for over 200 gbp for a part that cost less than 3gbp when thay were making them
once i have 1 and have tested it to see if it works i would be looking for 100+per batch of them if the price is right
this is the part >http://www.hpieurope.com/showimage.php?imgSrc=/graphics/parts/72208/01.jpg
if it cant be 3d printed is there any other options ?
edit i would also need the part drafted

i have a plastic sprocket approx dimensions are 10mm x 12mm does anyone have a 3d printer that can print one ?
( needs to be as strong as posable its a part for rc car that they havent made in 4 years so are very hard to get )
i can email picks and send the part to you
