3D Printing Thread
 

Hey everyone,

Since 3D printing has become a useful product that the average hobbyist can enjoy, I figured I could start a thread on equipment and projects folks are willing to share. A good starting point for those interested in getting one for business or pleasure.

I am starting this thread since I have run into a situation where it might be something I want to pursue or have someone attempt it on a machine they possess. I am hoping that today’s different materials/polymers allow for a viable solution. I’ve seen where folks have made prosthetic limbs so I am going to assume(slippery slope) that materials are durable.

The original item is ABS plastic that becomes brittle over time and heat.

It’s 9 3/8” wide by 2 1/8” approximately.

Is there a program that will allow an item to be digitally scanned with precise dimensions for a 3D print solution and if so, how good is it.

So let the good times roll and suggestions and recommendations are always welcome.

Cheers

I knew it was going to be a challenge since it is a precision piece. I’ve been looking at the different apps available but was not sure as to the accuracy. I actually just got off the phone with a company that can reverse engineer the component and provide me a laser scanned STL file to print from with exact measurements. They can also provide another format if I want to manipulate the image. I imagine they are more designed around the commercial application rather than the civilian market.

The quote will tell.

Since it is just round, that will help. What is that thing?

I would think a little time with a micrometer or a caliper would have all the measurements you need.

We have a small 3D printer here at work the we have been goofing around with that has peaked my curiosity.

My limited research shows a hobby printer runs a few hundred to professional models running tens of thousands.

I know you guys are tired of hearing my retirement business schemes but seeing as the technology seems to be taking off I'm looking at it.

As you said it is getting a lot of attention from the medical community or like your part there may be a market for scanning and printing random hard to find plastic parts.

Don't know if you do facebook but there are a few active 3D printing groups there.

PS: Some of the FB group have sophisticated setups, one guy has a metal rack in his shop with about 20 printers so I presume he is in the biz.
If you would like to give me the size of the part I would be willing to post a query to FB for you.

It's round. With a set of digital calipers it would be trivial to put in cad.

Maybe someone really good with a lathe could turn you one?

Maybe some local resources or mail order companies can do it in metal:

Local Maker Spaces often have 3D printers, Laser cutters and more.

I have a Prusia i3 MK2 I paid $500 for it used.

My son was over visiting and printing on it. He was so blown away by it he went home and purchased this for $270. In 2 hours he had it unpacked, assembled and printing.

In another life, I used to work for an injection mold company on the side. They would hire me to measure up parts then draw them in cadd. They would take my drawings to use with CNC Machines to create the molds.

A part like that would not be that hard to measure up and create in a design cad file and make a print file out of, as long as it is not bigger than the print area of a printer.

I've been using Xometry a bit through work, mostly for 3D printed stainless steel parts.

Interesting business model.

Not sure what the OP's part is for, looking like the lid for a coffee maker or cookie jar. Does not look 'precision' to me. An experienced CAD operator should be able to draw up relatively quickly. Print it out, if not quite right, tweak. Rinse and repeat. Printing may take several hours depending on the machine.

Edit: if this is a part for a common item, or expensive item, post the file(s) to thingverse and/or similar.

Wanted a toy to promote a book I’m working on. Got some local high school kids to make it for me in shop class. Cost me $20.

OK I guess I will take it there. 3D printers can be really really fun!!

It’s a forward spinner bulkhead for a 1967 Cessna 150.

Thanks! I will PM you some details tomorrow. From the hip, it’s 9 3/8” x 2 1/8”. The part in the picture is one I have borrowed and is decades old and feels brittle. Just looking for a viable solution.

93nav,

It’s a forward spinner bulkhead for a Cessna 150. Approx 9 3/8” wide by 2 1/8” tall.

A difficult part to locate for the particular aircraft. Used to stabilize the spinner and as time goes on, they develop some play and allow a slight wobble in the spinner that in-turns, allows the rear aluminum bulkhead to flex and then to will crack.

When they can be located, the going price is hovering around $600.00.

Here is my original,

The correct solution would to have had the forward bulkhead made of aluminum and then secured to the spinner via screws and nut-plates.

Cheers

Thanks! I’ll start checking those threads out.

Cheers
