Bad Brad with a 3D Print

This is me holding a statue of a man. This statue was printed with my 3D printer and this is exactly how it comes out of the machine.

I have to remove all of the support structure to reveal the actual statue.

My website is www.printo3d.com and my photo gallery of parts is photos.printo3d.com

Need something printed? Let me know!

3D printing is good stuff. I have a printer at my school an the only downside of it is breaking away all of the plastic that surrounds the image. Nice job though.

I believe that the statue portion is cocooned within the support structure, which has yet to be removed in this picture.

We have one of those in our Intro to Engineering Design class...Its pretty neat but its all delicate...You can't do too much without the small parts breaking but the big parts are kind of sturdy. Neat though. Looks like my friend's chess piece. He forgot to dimension all of the parts and it ended up being like 2" diameter with 2 spots that had like .2" diameter so it broke before we even took it off the black board thing, except yours is the opposite.

He is fully detailed so I had to censor him.

I took about two hours to break away all the grey support structure.

There are many forms of rapid prototyping.

FDM, SLS, SLA, 3DP, and LOM.

I would be here all night typing out how they all work, so it would probably be best to Google them if you want to know more about each.

Fused Deposition Modeling, Selective Laser Sintering, Stereolithography, 3D Printers and Laminated Object Manufacturing.

I happen to have a FDM machine. Basically its the same as a 3 axis milling machine except that it adds material in .01" layers rather than cutting material away.

There is NO programing involved with it. If the file has no major problems or errors, the Catalyst 3D printing software writes all the toolpaths.

I wanted to start a thread several weeks ago on how they work, but I never finished it.

I am juggling three things at the same time. Working to pay my personal/business bills, running my business, and trying to keep active flying my RC aircraft.

Well if it can be "sparsed" www.printo3d.com/solidvssparse.html then its obviously going to be much cheaper, but it will probably cost more than what the rules allow.

I'm not sure it's going to have the functionality you are looking for though.

Oh, and its only going to be 12" tall after I scale it.

Here is what the software looks like if anyone is interested in that sort of thing.

I took a Solid Works class at IVY tech. The teacher said if we get all the assignments done we could submit something for the 3D printer.
I was the only one who got everything done on time Actually I was a full month ahead of the class. I bought the student version of Solid Works.
My 3D project was fairly simple. I made a Rook. But not just any Rook. This one had stairs leading to the front door, windows and ramparts. It stood about three inches high.
I got an A in the class.

What is the ballpark price range on a rapid prototyped part? I'm completely unfamiliar with how much this actually costs, but I always come up with things I'd love to get printed. How much would something roughly the size of a softball cost?

[THIS IS NOT AN AD, as we do not do commercial parts]

I can't speak for brad but I work with the rapid prototype machines at RIT(we have the same one as brad, plus a few others) Typically we don't work with outside companies, but have been known to throw a few parts in as favors from time to time. When we bill inter-departmentally we charge $15 per hour the machine is running and about $20 per square inch of material. So for example that sculpture that brad made would have cost $509.35 (24.25 hours to print and contains 7.78 cubic inches of material)

now obviously in a university environment we have some flexibility with the billing, and take into account past parts and departmental relationships.

Thanks for answering Greg.

My typical charge is $20/hour. This however is not a straight charge. Larger parts cost less per hour to print and smaller parts cost more to print an hour.

This is simply because the price would be very steep for long prints if it was a straight charge.

On top of the hourly charge I add in $5 for each cubic inch of material.

Also I add in shipping costs, build tray costs, etc.

Greg, actually the statue used has 7.78 cubic inches of model material and 10.7 cubic inches of support material. My cost for the material alone is about $100.

Greg, I'm also not sure how you got your total because it does not match your material and hourly charge.

I just edited and uploaded this video on how the break away support technology works, so enjoy!


http://youtube.com/watch?v=fKToSeVkAAU

As always my prices are better than the competition and I may work out some great deals to FIRSTERS.

You will be surprised when you go to some of my competitors sites and see what they charge vs. what I charge.

cough cough www.redeyerpm.com or www.xpress3d.com

Trust me they charge an arm and a leg more than I do.

Please email printo3d@printo3d.com to discuss further pricing information.

I sometimes cheat with making flexible parts by 3D printing a cast/mold model and then fill the cavities with a rubber or plastic. There are many places to 3D print parts (google), its a matter of how much one is willing to spend. Also, figure out just how much support material the method of 3D printing leaves behind, it can be very time consuming to remove.

The college we machine at has one of these machines. It has been very useful over the year or so.... I even did my calculus project on it (modeling the revolution of the shaft made by a few equations); Most people had clay or posterboard things that were ugly and the 3d print was amazing.

Also, team 330 used the same machine last fall to prototype a transmission.



I've heard of a more advance version of this technology that can make more complex and thinner parts because the support material is water solluble so you don't have to go through the chipping away process.

We used one at a local university last year that used a real fine powder to print the part one fine layer at a time.

http://www.ems-usa.com/ZPrinter_310.html

Our school got a two week trial of a printer similar to the one you used. It worked excellent, and the school district just bought one for each of the high schools with project lead the way.
Great Job

Stratasys does have soluble support technology "SST". The support material is basically like the capsules of a pill. It simply dissolves when placed in a soapy like solution. These SST printers cost thousands more and probably worth the price if you pay someone to remove the supports from the kind of printer I have AKA Break-away Support Technology "BST".

As far as I know the cost of the support material is the same. The only thing that costs more is the printer, the extra expense of purchasing the solution and the solution tank.

Stratasys does also have a new printer out that uses stronger ABS plastic and prints in layers as fine as .007".

I'm glad to hear that these wonderful machines are being placed in schools! I wish I had one in my high school CAD class.

Here is a great video I found several months ago for educators that are trying to get 3D printers into schools.

@Brad do you recycle the waste product? (the break away material)

I think something like this may be a little more say "useful" in highschools for courses such as pltw simply because it seems easier. The students can take home the part to take the break away support material off. And for the simple part that student would make it would be nowhere near 25 hours of print time. If other schools are like my high school was the teacher could just let it run all day because there was always someone in the room Although I bet this is much safer to leave alone then a CNC mill with a running spindle speed of a few thousand RPMs. It is also probably more space efficient too, along with CLEANER. No wax chips all over. Not much setup time. Oh and also you don't need 2 classes to learn it all (1 for CAD and 1 for CNC software)

We have a "few" rapid prototyping machines at work. They make all the difference in the world when you can simply email a .stl to the machine shop and get your part back in a few hours (if it is short). Even better, as an EE I can hand a model of my circuit board to an ME and get a box back the next day

You really have to see what the higher end models can do. There is a demo piece in the machine shop - a bicycle 3 inches long. The wheels have treads, the handle bar turns the front wheel, and the back wheel spins. Gorgeous. I _think_ that that one has sub thou tolerances.

If you can't get access to a 3D, a 2D can do some cool things to (they just need a little love). Try castleating some polycarb. Looks great.

In any case, I hope this type of stuff becomes accessible to more FIRST teams. Thanks Brad for the cool pictures.

Yes the waste product is ABS and can be recycled. For now I just keep the scrap in containers.

I cannot recycle the scrap into usable product again though.

The machine takes two cartridges of material, one is support and the other is model material. Each cartridge contains over 50 cubic inches of material in .07" diameter wire and costs nearly $300. I do not know why, but Stratasys does not recycle these cartridges. Also each cartridge is regulated to by a microchip so that you can only use the alloted amount of material before it is "spent".

In other words each cartridge has a lot more material in it than what you can get out of it. This microchip basically keeps other suppliers from making usable material for the their printers. It would sort of be like buying a "knock off" a HP printer ink cartridge.

The machine is about the size of a refridgerator, weighs 300+ pounds and about 1/3 of the height of the machine is a storage/stand.

The machine does not have to have an operator while printing and is made to left unattended. It does have is problems though. If the power goes out in the middle of a 25 hour build you lose the entire model. Also if something breaks off of the model while printing it will just print a mound of plastic, unless you cancel the build.

You can see an example of this here:

http://www.youtube.com/watch?v=pnANG53o9SM

The resolution, accuracy, strength and finish you want comes with a price. The higher end machines are much more expensive than the machine I have.

This first picture is a "spent" cartridge according to the regulating microchip, but still has lots of usable material.

1024 has been using FDM for quite a while too. Over the years we've found theres places to use it and places to not use it.... but really it depends on an application by application basis....

Some of the best places we've found it useful are applications where items need to be feeded, such as poof balls for the aim high competition. If you'll remember, FDM could be found in the shooter wheels, shooter guards, feeder system, as well as the drive sprockets for the track drive.

The school we are located at (McKenzie Career Center) has a Stratasys FDM Maxum rapid prototyper (24x20x24" build size).

At the place where i work we looked at getting a smaller Dimension line FDM machine.... the price of the machine isnt what stopped it... its the material! As stated in previous posts, it costs hundreds of dollars to make a part of any decent size.

Which reminds me... FDM'ers out there.... have any of you wondered if string trimmer line (which you can find in ABS as well as PC) would work as well? I mean... talk about a lower cost option... it might be a conspiracy!

...but then again who wants to risk their machine... hmm.

A lower cost solution? (I found this website and immediately thought of this thread.)

Home built ~$500 machine with $0.37/pound material. But there is a BIG "yeah, but..." attached to these prices. (It's sugar!)

I forgot to add that this "printing" is exciting. Wish I had it many moons ago building architectural models in college....

There's also Fab@Home, which does some pretty pretty cool stuff for $2500 or so (less if you can scavenge parts). There's no way you could prototype robot parts with it, due to a lack of precision, but hey, you can print with chocolate, cheesewhizz, epoxy and other cool stuff. I've been looking into making a modified version of this and trying to up the precision.

I've been waiting for the release of this machine since I found out about it month ago.

There is a one page article in the Sept. issue of Pop Sci about it.

They predict each .1" layer will take 2 minutes to make!

I'm not sure if thats a typo, but that is very impressive if it can work that fast.



This is a quote from the article:
"fabricate for example, your own rubber watchband or iPhone case."
