3d Printing

Cool project but not practical. I'd bet it cost more in plastic wire than a real grit guard. And then printed stuff is about 30% as strong as cast or injected.

Exactly, that's one exspensive grit guard. My friend has a 3d printer, he made a v-8 engine about 4 -5 inches long, pretty cool.
 
I find it hard to believe that the 3D printer can't make a Grit guard even better...

The possibilities are endless with these machines... Surely the current Grit guard design isn't "perfect"... Or is it?

This statement is not true

That was pretty much the whole reason. I just wanted to see what I could do. A friend of mine got a printer, so I started playing around.

I will however be printing the grit guard extension I created. They don't seem to sell them separately from the universal pad washer, and it's the only piece I'm missing from my homemade pad washer.

That could get you in a lot of legal trouble.
 
Completely off topic but I kind of agree with Allen here. Folks that are downloading torrents or other copyrighted materials on P2P services are not selling it, but posting it for free.

Just make your own design! Then you can sell it
 
I' not sure this is fact but I heard a guy bought a 3D printer... Made a new 3D printer and returned the original. Sounded a little far fetched to me...but you never know. Cool technology.

So, anyone here into 3d printing?
Click to expand...


I am. We have 6 of them at my work. Dimension SST 1200es's, and some 768 BST/SST. :props:


We're using Pro/E and Solidworks and I also do some animation with 3DVIA Composer.
 
Here is a small one I recently made for functional testing.



It's purpose is to elevate an antenna off of a circuit board by 4mm.

Sure it is, just like you can tape movies off of HBO, as long as you don't charge people to watch it.

One is a copyrighted item the other is a patented item.

At any rate....

Your analogy is not accurate as it applies to the example at hand of the Grit Guard. You could play the recorded movie on five TV's stacked one atop the other, but you are still only watching the one movie. If you make a copy of the Grit Guard you bought and put is in a 2nd bucket, you are receiving additional benefit and have deprived the patent holder from receiving compensation for that 2nd Grit Guard.

The not charging also has nothing to do with it. No one charged for access to their uploaded music when using "Free Music" websites like Napster, but there are lots of people who were caught and fined heavily for their unauthorized use of copyrighted materials.

Making a copy of something that you do or do not already own (Grit Guard) for any use is illegal.

Now way around it, producing a copy of a patented item; whether it is for you own use or for sale is irrelevant. Both are illegal.

I'm sorry; you are right. However, have we even established that there is indeed a valid patent on a Grit Guard? (Ok, I just looked--#7,025,880). Would they care if the OP made one in his house for his own use? Probably not. Would they care if he posted up the .stl file here on the forum? Yeah probably.

Since someone mentioned Dell and 3D printers, I looked, and they seem to be getting ready to sell not only printers, but what looked like a 3D scanner...what a can of worms that will be if someone can buy a grit guard and put it in their scanner and make copies of it.
 
Man I didn't mean to start a big debate haha.

Like I said, the Grit Guard was just me playing around, seeing if I could do it. They aren't expensive, so I would just buy the thing. Plus, I do have some sense of customer loyalty. They make a product I like, so I'm happy to buy it from them.

The extension is a different story just because it is not sold by itself. I'm not selling it; I just want to print one out for my own usage. I am no expert at patent law, but I would be very surprised if the people at Grit Guard felt the need to sue me over it. If it's really that big of a deal, I'd be happy to change up the design to something different that still does the job.

And if there is some way to improve upon the Grit Guard design, I would print that out because I love tinkering with stuff and seeing what I can do. I'm a software engineer by day; this is just a hobby. I'm not looking to sell anything or start a competing business, so if I did come up with something I would be more than happy to share it with the good people at Grit Guard, they can sell it all they want.

But anything I create, I would also share here, so people can print it freely. As a programmer I'm a big proponent of open source software (code anyone can use, rather than code that's restricted and licensed out by big corporations for a fee). Open source allows people to build on ideas, rather than restricting everything that is created. Eventually this is going to be a big issue with 3d printing as well. As long as people are willing to share ideas, then we can keep coming up with great things. But if everything that gets designed in cad gets restricted by patents, then this technology will never live up to its potential.

I would love to have the extension / top unit of the Danase Dirt Dropper; that would fit into the hole location on the Grit Guard. But I don't have a 3D printer to make one...

All the extension does is slide on. It has 2 cylinders protruding from the bottom that fit into the circles in the center of the grit guard. For this you would just need a large cylinder, with 8 gaps, to fit into the spaces between the rings

OP, Quit working on grit guards. Make this happen:

Star Trek Voyager: Tom Paris orders Hot Plain Tomato Soup

Lol I love when they get annoyed with the replicators.

Is the Grit Guard patented? I have a package from about 10 years ago that says "patent pending". Besides, if he's not selling them he's not violating anything. If he whittled one out of wood, would he need a lawyer (if he wasn't selling them)?

To answer this question precisely, "yes". A product patent prohibits anyone other than the patent holder (or his or her licensees) from making, using or selling the patented product during the life of the patent.
