AtomicProf needs help with 3D printing
« on: February 25, 2014, 03:55:16 PM »
Hey,


I'm working on a prototype for a kickstarter project.  I'm looking to finalize the kinetic art / marble run and see if there is interest in it.


I need help making plastic inserts.  They will be 1/4 inch in diameter and about 1 to 1 1/2 inches long.  One end will have a hook to attach a rubber band to.


If you are willing and able to help with this please let me know.


I'll be in the lab tonight (Tues) at around 9:00.  And can make myself available during the day or evening.


Thanks

Do you have any kind of drawing to help? Is it essentially this but smaller? http://www.ikea.com/us/en/catalog/products/10079366/
I like colors.

OK -- I'm trying to print this thing.  It is 6.5 mm in diameter on the cylinder.


So far i'm getting some strange things.

Is that new black pla?  it looks like it was old moisture laden stuff.

Try using the ultimaker.

Try printing a plate of twelve of them. Tall, narrow prints print best when the nozzle doesn't stay on one spire constantly.

If you send me the .stl, I'll give it a go on the DeltaMaker...

Possible causes...


filament too hot
speed too slow
no fan


I can agree with cope, if the nozzle stays in one place too long, it'll just start making a melted mess of things. A fan can help, so can ganging them up so one can cool off a little, as the other is printing.


*** ADDED After the fact ***
Or you can ask Ian to print it on the Deltamaker :-)

OK all -- thanks for the tips.  I did put a fan on it.  Then I was trying to print five, I threaded in new black PLC ( i guess that's what it was)..  But the it wouldn't feed.  the wheel was turning at the end of the nozzle.  I ran it through manually and it spilled out some melted filament.  But then It didn't feed for the print.  So that was that.


However, my last print I did the following which was greatly improved
1 - lowered the temperature to 200C
2 - reduced the layer to .35 mm
3 - reduced the feed rate of the filament.  And the result was looking good until I ran out of PLC..  :(


IAN.  thanks I'll send a file your way.
