3D printed part

67dart_drop_top · Nov 24, 2013

I just finished printing my first working 3D part from plastic. My students have printed cooler stuff than this, but none of them were actually useful. This is a part for another FABO member. He sent me the broke part, and I had to recreate it.

I am posting a few pics of the CAD drawings, and I will leave it to y'all to identify the part before a final picture is posted. Truth be told, I did not realize how bad my pics were until after I mailed it back. I am at the mercy of the recipient to post a final pic.

No cheating!!!

I drew the part in two subparts and then put them together before printing. The measurements are in millimeters for no particular.

Offhand I'd say that's the starboard interlock safety purger drum for the Maxim fender mount 1.2mm air motor chain driven self charging gatling gun

X2 ^ what he said.

looks like a cahooter valve O ring plunger to me

It doesn't look familiar to me, but can you go into a little detail about the 3D printing?

new style muffler bearing?

No No No that is the retainer ring and plunger valve for the muffler bearing.....Duh

I thought that was a cross between an elephant and a rhino.

I cheated so I can't say

LOL That's the part the Martian on Bugs Bunny was always trying to find for his "Space Modulator".

The pink part looks like it has teeth. A speedometer gear perhaps?

I know what it is supposed to be. I don't recall the OEM had a tapered shank though.
I am recalling a case of machine shop working off a worn sample and going to a lot of effort to reproduce the wear.

67dart_drop_top · Nov 25, 2013

Damn it. I did not think of wear taking off that much material. Recreating that taper was the hardest part--probably an 5 extra minutes out of the 30 minutes I spent measuring and drawing. I figured there might be a little wear, so I rounded up the measurement to the nearest 25/100ths of a millimeter.

As for the 3D printing, the CAD drawing is broken into slices. In the case of this part, there are 62 slices. Each slice is printed in a layer of plastic. After a layer is printed, the table of the printer moves down about a half of a millimeter to accommodate the next slice. It is like an ink printer that lays down plastic instead of ink. And instead of the paper moving, the table moves down. The printer head is heated to over 400 degrees and moves all around. There are a ton of videos showing the process online, and there are a million 3D print files that people have openly submitted for use. Check out thingiverse.com if you are interested.

My latest print was another useful item. Instead of buying a PVC cap and drilling holes for my aquarium filter, I designed a cap with holes as part of the printed image (see below):

Very cool. How large an item can you make?

Scientists predict we will 3D print working hearts and other organs within 20 years.

67dart_drop_top · Nov 25, 2013

The manufacturer has shown that one of my printers can print a full sized basketball. I do not anticipate that being a project, but I think the point is that it can print anything less than or equal to the height, width and/or depth of the ball.

The real life application that I like to mention to my students is when we start real space travel. We will not have to carry a lot of spare parts--just a lot of material that can be used in printers. And I do not think it will be limited to plastic in the near future.

Just some FYI, the plastic used in the small part was less than $.01. The PVC cap was $.03. The printer cost $1500, but they expect them to be well under $500 in the next few years. They look less complicated than an ink printer. Look up Infinia 3D printers.

Alright guys...I'm the guy who had "67_Dart_Drop_Top" make this part....and here's the pics....(by the way, its one of those plastic pins that keeps breaking on your heater controls)....

I really want to publically thank "67" for taking on this project. Its tiny, but a needed part.

4spdragtop · Nov 28, 2013

Very cool, ballpark price??

65Val · Nov 28, 2013

Steve...I think we'll start selling them at $19.95 ea....but you get a free "Pocket Fisherman" or "Ghinsu Knife" with every order. Your choice!

"Now how much would you pay"!!! LOL!

Tincup · Nov 28, 2013

I am in the process of ordering a 3D printer for work, I should be able to make some cool stuff. I'm curious to see how well the parts hold up.

67dart_drop_top · Nov 28, 2013

The costliest part of selling these parts is getting them to a post office. The closest one is 15 minutes away. $7 delivered would be enough incentive to print one out, pay for packaging and ship it out. Y'all keep me in mind.

grimreaper · Nov 28, 2013

A friend has a 3D printer but all I see him making seem to be produced with a product similar to hot glue. What type of materials can the printers use that are durable for functional parts?

Got a Ginsu and a Pocketfisherman...How bout a Schticky?? LOL
Hey Val, what year are the controls from?? Im looking for 67-9 Cuda?? Also are both plastic sliders identical??

I did a little CAD in College and loved it...very frustrating trying to get teachers help in a class of 30 though. Nice work and see my above question to 65Val. If they are the same, I will take 4 of them. Shoot me a total and again, nice work!

Steve...Sorry...sold out of Schticky's, but I can let you have a K-Tel Record Selector or a Veg-O-Matic...let me know!....I believe '67 Cuda, but don't quote me as I bought it at a swap meet, and they just looked right for the parts I needed. Yes, both are the same...I used the bottom one out of this parts control in the top of my Dart's controls.

Alright!...a down payment on my Florida condo! :blob:
