Projects As seen on TV

Was at a local college the other day.They have what is called a fab lab.It had 3d printers,laser scanners and other ***orted equipment to help manufacture prototype parts.Its free to the public just need to donate to pay for materials.In order to be called a fab lab it needs to be open to the public.If you google fab labs there all over the place.Thought it was pretty cool that there out there for the public use.

 

We have been doing that in dentistry for years.

 

Y'all print 15" teeth ?

 

HA no but we can scan anything less than the size of a dime and duplicate them in any porcelain you choose!

 

Now this definitely looks like fun.I`ll saddle up and go along for the ride.31vickey,thanks for posting.
Good luck.Have fun.Be safe.

Mmm, porcelain blown Hemi water crossover!

 

I will need one of those when they are done.

 

Who makes the one you have now? Is this the same casting?

 

There is a gearhead kid here offering his services for cheap. Pm if you want.

I don't have FB. So I sent the link to my wife and it's not opening for her.

 

At the moment, nobody makes it.

That was a PAW product, and PAW is no more.

They aren't unobtanium in price. They simply don't exist to buy, at any price.

 

Yes. Sorry, I think you need to be a member of the group. I will try to hook you two up somehow .

 

If you make a new pattern or buck to sand cast from, it will need to be 1-2% larger to allow for shrinkage. If you use the existing alum part for a master, your new part would be smaller.

 

So Tuesday is the late night.
Finished repairing the files.
Set it up in an STL file.
The printer software said this 45* arrangement was optimal. It needs support Material on the way up. That support material gets dissolved when it's finished .

Here's the printer getting started doing its thing

 

I got this about 1 HR ago.
Painfully slow process. The software estimated 28 hrs to print

 

This phase of the mission is complete.

 

Effin amazing!

 

How about using that .stl file and find some outfit with a SLM (Selective Laser Melting) unit?

That might be "As seen On TV - Part II"

 

I work ICT and even the primary schools have 3D printing these days so 5yr olds to 12yr olds do 3d modeling scanning and printing.
Admittedly many have cheap printers as time/quan***y is a thing when you have a cl*** of kids wanting spaceships, dice or prints of there faces etc.
If you are scanning you need a decent one really. Although some phone apps will work taking a gizzilon photos of a static object on a turntable to make the object file but then you often need go fix the mesh as things like reflectivity can screw things up with these.

A mate had his 10 year old make him up an intake that he took down to the foundry and had made up.
I have plans to use 3D printing alot in my current build a bit further down the track.

 

So how good did the dimensions come out after you have to do all those calculations for shrinkage etc.

 

Found this company here in Canada. Not sure if the plates are big enough and if they would do a quotation based on your file:

What I've printed is an exact copy,
At this point in time that is what I need.

 

Sure looks like it came out good!!

 

Wow! Glad you finally found that crossover.

 

Cool Beans!!!

 

3D Systems, Stratasys and Proto Labs are all larger companies that will print in DMLS from aluminum powdered metal. Your 15" dimension may be problematic; many DMLS machines are limited to 12" or so.

Now that you have an STL file, you can have a Quickcast pattern printed for investment casting. I did this for a custom rifle receiver once. I paid $900 for a part cast in 17-4 PH stainless. It ain't cheap but when ya gotta have it, you gotta have it. Still, it would be worth checking out.

Darned impressive '31!
