Got a 3D printer now, it's fun!

So yesterday printed the top portion of a caliper in our 4 piston range. This piece will go to the spring maker so we can get our pad spring sorted. Here are some pics. Came out rather well. Now Printing is the two halves of our Historic caliper that we are aiming to have FIA Homologated.

haven't watched the vid yet - here is my attempt



you can see the smoothest parts are where it dripped on the print.. but there is a nice gloss to the rest of it.

That's not bad. maybe a bit of hand sanding first would bring it closer to full gloss. I'm going to experiment with some PVC pipe primer for PLA over the weekend. I'll post the results

I've had reasonable success by rubbing the parts with cloth dipped in acetone. Have to be very careful of course.

Did not make it into the office yesterday so when I came in this morning I had this waiting for me….outer half of our Historic caliper. Came out great. I think I have this printer pretty much sussed out. This part part came out perfect.

NOTE: I did not spend time cleaning the piston bores and pad areas

if you sliced that in the right spot - you could print it without supports and glue it.

Yeah I know. I hate gluing things together unless absolutely necessary.

[GSRman]

absolutely - but i hate support even more.


Had another go at the long-method smoothing - still ended up with a puddle on my foil - impressive partly - hoping it won't discolour at any point -

No pics to show for my PLA smoothing experiment. Maybe I'm using the wrong shit but the PVC pipe primer did not smooth the PLA. After about 3-4 hours, the PLA was soft but not melty enough to make the surface gloss up. The vid I saw said use PVC pipe cleaner rather than primer. Is that just the 'Murican name for it or are there two different products??

[GSRman]

can't imagine its much different...

would soften ABS i bet.

Pulled the second half of the historic caliper out of the printer this morning. Came out ok.

I just had a look at the Home Depot site and even from the same company, they have different cans for PVC Primer and PVC/ABS Cleaner.

< 1 star safety rating for sure. (crash test video would be awesome)

I like how they still found a way to make it gaudy.

Bit of acetone on a rag? Haha

[GSRman]

acetone in lunchbox with paper towel - 1hr 30 mins (rear) -
