3D Printing for metal parts

Hmmm...seems, another member has completed the process🤔

Yes, and 324darrin has shown pictorial proof of the product.

Much better than unfulfilled promises.

If it's not here it's not because I didn't try. Steve

It appears from the pic that much post-mold polishing would need to be done to get an acceptable finish.

Jake, I'm confused by this signature from your current posts:

Member #7416  Since June 1990

NO Club.. 

Just a lone wolf..

Are you a member of KFOCI?  If not, then you don't have a member #.  If you are, then you do.

Terry, there was a rather thorough discussion regarding the cross drilled holes in the door handles on page one of this thread. You're thoughts are that there should only be one hole but another member indicated that all of his handles have two holes as mine do. So this raises the question or maybe indicates that they were produced both ways. Regardless of the number of holes, the strength of stainless steel should negate the issue of breakage.

Jake, where did you come up with your cost per handle? have you been in contact with the printing company that I have been dealing with. Please don't muddy the water here with conjecture. I am as anxious an anyone to find out the cost. I will let you know what it is when I know and anyone that is interested can work directly with the printing company. I am not in this to line my pockets nor do I want to be the middle man. Thanks, Steve

Steve...Thanks again for your efforts on the handles! I'll be one of those in line:-)  @Terry, I included a picture of something Adam sent me awhile back. Demonstrates the rough part and polished side by side. It is a pretty remarkable process...If I recall this pic was formed in plastic.

I still do not understand what the other set of holes are for.
Looking at the mechanism, if one uses those holes, the handle would be installed 90 deg. orientation from using the original holes.  One would need to index the square shaft 90 deg. to get the handle in either a forward or rearward orientation.
What am I missing.. why are they needed?

[324darrin]

Terry, I am as perplexed as you about the cross drilled holes. The fact remains that they were manufactured both ways. I agree that it does not make any sense due to indexing in the correct position not to mention how the extra hole affects the integrity of the material. Unless there is documented evidence from Kaiser regarding their reasoning, we may never know the why of it. Steve

It looks like the door handles will be ready later this week. I have been invited to tour the 3D lab and then peruse a 30 car collection owned by the father of the 3D lab. With their permission, I will take photos. My son has taken a day off work to join me on this field trip. Very excited.  Steve

That sounds like an awesome experience and a great potential story for the Bulletin:-)

Or a better story for the Quarterly!

Looks like I need to get a part time job if I'm going to keep getting parts made with the 3D process.
Here is the response I got when I asked about the cost.

"Here's a breakdown showing what you would typically pay for these parts:
3D Scanning: $265.80
3D Printing: $790.50 each
Polishing: $150 each
Total: $2,146.80

3D printing is an expensive process. I obviously will not charge you anywhere close to this amount since I never provided you with a quote and was using the parts as a training exercise. I want you to see the parts and be happy with them. I am thinking $500 each, $1,000 total would be fair. Let me know if this sounds about right to you...."

I was not prepared for that amount but feel locked in and obligated to pay him for his services. so tomorrow I am going to go out and see the lab and pick them up. I do not see having any more parts done by the 3D process. this set me back a bit so the gas tank cleaning will have to wait until next month.  Steve

Thanks for the information. I think, over time, the cost to do any 3D work will come down...remember when a new VCR cost $1200 or more and the price of a flat screen TV of any size was astronomical? Like any commodity, once folks figure how to do it better, it'll get cheaper.

Until then, I guess we'll have to find someone who still does brass or pot metal casting.

I have not followed up on this. The  original idea was to make 3D printing available to the public as well as courses in working with same.I would love to make a 3 prong, 1953 Henry J hood ornament tip!

To be honest...I was expecting just slightly more from the research and networking I’ve been doing, but that breakdown falls into everything I’ve encountered. On a positive...the scanning does not need to be done again( Will they share the CAD file? Nice way to get a copy of the CAD file for club records?) ...and as the other companies mentioned(as with any parts) a price break only occurs with quantity printing per tray, not so much as a piece at a time. I need to schedule a few more summer festival gigs to collect my funny money;-) Thank you again for following through with the process!
