3D printed pool cue

You might be an executive or a president off the forum.

Your still not negotiating me into doing free work after the free sample.

If you are not interviewing for someone, then I am interested in private research facility. Most of my other posts clearly indicate what type of work I want. I can live without the patents but I will expect clearance above the usual scientists.

I am interested in positions that will pay for my security clearance and relocation.

I dont post technical for fun. I am looking to be hired.

I thought you were a teacher warping the minds of our youth? Heaven help us.
 
Did anyone figure out how to print chalk?

Or leather like tips?

I can provide free instructional guidance.

How would anyone feel about a ferrule with an angle or slant?

I'm pleased as punch as Earl/Rogan would say:) My first cue. It took me 27 years. I got my first metal lathe in 1996 and all my buddies have been asking since then when I would finally make a cue. ha ha.

The butt all screwed together is definitely flexible. I think it might still work though. I will take it to the pool room tomorrow to hit with it.

It's going yo be terrible. A guy I know has a pool cue disguised as a walking stick. No one questions a walking stick.

Update, I got to play the cue last night for the first time. I was at a friend's house who had a beautiful GC1. He was having trouble with his alarm system, and it was going off every 20 or so minutes. When I took my first test shot, the alarm had went off simultaneously. I said: "this stick sounds worse than the alarm". Its was a nasty high pitched "tink" sound. Then my buddy took a shot, and the stick broke at the 5/16-14 threads, right where I expected it to. Both shots were medium speed.

Pros: The stick was perfectly straight, rolling the butt by itself, and with the 314-2 shaft attached.

I'm going to order a steel 5/16-14 joint pin and try again. That will be a much more fair test.

Is there a way to heat treat certain areas to improve polymer chain length? I don’t know much about the shear strength of printed materials.

Could be, I haven't looked into it. I used to use FDM printers at work 20 years ago. We would wipe acetone on them after printing in ABS to bond the layers better. We quickly stopped using them as there were much better rapid prototype technologies. In the consumer space however, FDM is about all that is affordable.

I would have liked to print the pieces horizontally on the bed. That would have made them much stronger. However, I don't think they would have been straight at all, and I'd have to use support material for the threaded areas.

If the metal joint screw makes a big improvement I'll probably continue. If it still sounds like crap, and or breaks again, it might be time to abort:)

Metal joint screw ordered today. I wish I had ordered it a week ago, but I forgot about it.
 
Imagine printing them in zero g or at least lower g. Even programmable fields depending on materials.

Commercially it could be allowed in some licensed labs. Just call the school and ask for the dept as professional organization with money and clearance.

I think you mean in vacuum. Printing in zero G is both super challenging and pointless

Ok so in my imaginary drone, that is fictitious, it will have to print in zero G. Printing your own fuel means infinite power supply.

Print a fossil fuel carbon in space and wham, we are good to go. Whatever payload can be reduced and offset into future problems with future resources.

Zero G is the name of my band. Electron valence band that is. Quantum leaps nearest the favorable band gap can be printed with FDM in the academic department in Utah University. Only the tenured faculty have access to the room. The room is suspended on a bed of rubber gaskets for reduction of noise and thought. Like a monster at breakfast in Scotland, or in a lock’s nest or Loch Ness all the same. Cages made of bananas don’t hold monkeys because they can just eat through. Peel them first though. What is an animal that is trapped by its own food? Is it really a zoo? Or is it an experiment in itself? I think this problem can be solved with redox reactions, I am doing the research now. We have all watched the Twilight Zone, my favorite episode is the pool episode where the lawn mower fails to start on the wing of the airplane in space and everyone descends into hysteria. Billiards is a bit like a rusty hinge. Writing in English is the most ingenious torture ever devised for sins committed in previous lives. The English reading public explains the reason why. When the Irishman is found outside of Ireland in another environment, he very often becomes a respected man. The economic and intellectual conditions that prevail in his own country do not permit the development of individuality. No one who has any self-respect stays in Ireland but flees afar as though from a country that has undergone the visitation of an angered Jove. The soul has a slow and dark birth, more mysterious than the birth of the body. When the soul of a man is born in this country there are nets flung at it to hold it back from flight. You talk to me of nationality, language, religion. I shall try to fly by those nets. Shadows become the giver of light, the meek feast on the darkness, and you, sir, have neither.

I could name handfuls of scientists from top National labs because of personal experiences. As well as their instructors or parents.

You just have to sit down and read the book, its what most of them say.

Just sit down, read the book and talk about it.

If you can use an electrostatic field to control the placement of molecules, scientists can develop very specific properties in popular materials.
That is where "beams" play a role. To push and pull the molecule to a specific location in the atomic structure.

That level of precision will be helpful with proteins and DNA.

When you understand the book, everything else gets easier. The problem is reading the book, everyone just wants to get an A on a test.

Thank you grade inflation. Pay the fees

was it only the joint connecting the shaft that failed? printing horizontal w. support shouldn't be a problem with the AMS

You can anneal PLA for added strength. I’ve had mixed results and you will lose some precision

When it comes to making your prints stronger, all you need is some time and more heat. Read about annealing PLA and PLA heat resistance!

Yes. Everything else was fine (on two shots at least).

Why not just use a house cue wherever you are going? Seems like a lot to go thru to make a cue that could very well play like total crap.

I thought I could get the broken piece out by scoring it with a knife and twisting it out. No dice, I made the threads too tight. Thankfully I had EZ-Outs. They worked great.

I'm flying back home to Atlanta next Tuesday. If the joint pin does not get to Philly (my dad's house) before then, I'll have to wait a month or so to resume this project.

This was my issue with 3d printing joint protectors. On a 5/16 joint pin, it was too fragile to stay in one piece - twist a little too firmly and it just snaps off. 3/8 will fare better, but as a cue joint, still may face the same outcome.

I didn't read the whole thread, but I will assume yours is pla or petg. I plan on trying out nylon very soon to see if there more rigidity.
