Who has a CubeX Trio with soluble support? I'd like to contract a part with you.

[tgw...@gmail.com]

I have a special part which can only be built on a 3 nozzle FDM. The CubeX Trio is one of the only machines I've identified that can do it. Materials must be white ABS, black ABS, and a soluble support.

Please write me if you have this capability. I will contract you to make one prototype, and then a batch of about 20 of this particular design.

Thanks!

Trevor

Trevor,

Here is my concern.

ABS is prone to warping and stress cracks caused by differential shrinkage as a layer cools and a new hot layer is printed on top.

In general, the best solution is a heated chamber such that the plastic doesn't cool to room temp until all layers are printed.

The best support material that can be dissolved as a support material compatible with ABS is HIPS.

A Cube X trio is not a heated bed, let alone a heated chamber

A CubePro trio is not a heated bed- maybe an enclosed but unheated chamber

I don't know that HIPS is a material sold for Cubes? PVA is a ripe disaster.

On top of all of that, any part in 2 color needing support sounds like a ripe disaster, let alone the fact you eluded to only support that is completely soluble support (indicating same material support won't work).

Again, I think you have more faith in consumer FDM than you really should. 

The closer you get to strict requirements, the further away from FDM being a practical solution. 

For example, why cannot you split the part for sensible support free printing and glue together?

Do you really believe that your print will be stronger printed as one piece? I guarantee that is a completely false premise and requirement.

I'm just gonna flat out tell you no, it's not going to work and even if it did, the prep and cost by a user to do this for you- let alone 20 units is out of this world.

Please ignore Jetguy's reply; he does not understand my application nor the work I have already successfully completed on the project.

If you have a 3-nozzle FDM, please contact me.

Thank you.

First off, I fully understand the disaster you are asking someone to undertake. 

If you were a man about it, you'd destroy your own printer rather than asking someone else to print this for you and take the risk.

Soluble support material seems to be missing from that list

Hmm, Don't see it here either

http://cubify.com/en/CubePro/Supplies

So just to be clear, you are looking for someone running Cubeit, owns a Trio, and is willing/able to run soluble support material and print 2 color ABS.

Because what you are asking for is NOT even officially supported or even possible.

[Hugues]

It's possible with a really good cubex trio owner who work with HIPS on one extruder.
But as JetGuy said, it's an hard job for this printer with abs no heat chamber, no heat bed in stock version.
But I'm sure they are people to take your challenge. Just be sure that they use cubeitmod an if possible heat bed and close chamber in their workflow.

 I have a 3 head printer ?   I also have 4000 print Hours of experience in ABS. I am thinking about it  

[Jetguy]

Sorry for my tone. I'm not trying to be a complete jerk to the requester or the group at large. It's just I did the homework on the question at hand.

A CubeX trio is a $3,300+ printer according to my research. I just happen to have 2 CubeX Duos I've brought back from the dead and know all of the problem with using stock extruders/nozzles and that the user would have to use Cubeit to use alternate materials. I know just from a thread going in the last 2 days filament of certain diameters can be problematic.

But the original requester came off as someone who simply saw a CubeX trio is one of the few machines with 3 nozzles. They didn't check what materials are officially supported or what it would take for anyone to even attempt the original request.

My goal in my post was to warn the poor inexperienced owner of a CubeX trio the requirements not brought out in the request. In other words, I would hate to see some unsuspecting user go OK, agree to this guy's request, and proceed to really clog and jam their extruders or waste time and money trying to print something that could cause them problems.

Is this guy going to supply the materials?

Is this guy going to replace a nozzle if it jams and is permanently ruined (PVA can burn to a black gunk that is death for a nozzle)?

Is this going to pay you for shipping, time, plastic?

Will he pay even if the attempt fails?

I'm asking these questions as an attempt to educate anyone thinking of taking print requests for money. It sounds great at first but when it all goes wrong (and that can and does happen often) you find yourself with a broken printer and no money and wasted time.

Again, I've had serious experience with this. I printed a 50 unit set of parts for a customer in ABS with each part consisting of 12 printed parts each all over 100mm cubed. To meet his specs, I had about 75% succes rate or 25% reject rate depending on how you look at it. 

It took nearly 2 months running 3 printers near non-stop.

I had to rush ship plastic because again, the customer wanted specific colors. I ran into lot dyematching problems and couldn't run any other brand of plastic.

So yes, you really need to take a serious approach someone casually asking "can you print 20 of these for me".

Here Here!

Age & Experience speaking here, these are very valid concerns.  In my youth I would be too quick to take on projects like these that might seem like a great opportunity, while not understanding the risks, which could often end in misery for all.   Jetguy, I second your words of caution.  Thank you.

There are MANY commercial 3D printing services out there, even 3DS offers services.  Trevor, have you contacted commercial services yet?  Or considered making your part by allowing the design to becoming multiple pieces? 

---  Or perhaps considered liquid casting the part in a silicon mold with polyurethanes or epoxy or another resin. <---  That can be a great way to get to 20 parts, carefully shape one, with a fine fit and finish, then let create a mold from it.  A great way to get around the fact that surface finish isn't the best in FDM for presenting parts to others.   The silicon mold can do awesome things like ignoring a draft since it can stretch during part removal, etc.

Hi Trevor,
I have a trio machine and I can use any proper material. PS soluble material can be HIPS or PLA depending on the solvent that will be used.
let me know what you need and send me the model so that I can evaluate the job.
Regards,
Maged

Hi Trevor;
I have a stratsys that does the job. I also have
I have a cube x trio. It has a heated cabin, but the material that they say is soluble is not. It uses a PLA plastic wich only gets soft but it does not go away. in other words it does not work.
