Hi community,

can you help me in printing the attached design?

I did try Ultimaker2 and Form1+ but both failed.

Any hint, offer, explanation is highly welcome.

Looking forward to get this solved :wink:

Thank you.

Matthias

P.s.: My personal limit would be ~50€.

Maybe increase the wall thickness a little? 1mm seems optimistic for low cost consumer grade 3d-printers, especially with the size (height) of the model. Adding some kind of base (a ring) to the models long thin “legs” to have a bit more surface sticking to the build platform would help a lot too. (You can always cut that ring away once the print is done) And you need a big fan cooling the model while it gets printed on FDM machines, again, due to the thin walls the plastic would stay “soft” for too long otherwise and could bend away from its original spot making a big mess out of it. Maybe that already helps a little to get you going…

Hi Andreas,

good points!

One thing we tried was to put a very thin layer between the legs to give it more stability but for some reasons it didn´t print so well. The layer was too thick to remove it easily afterwards, so that it looks now more like a solid pylon…:frowning:

The idea to increase wall thickness in combination with some rings sounds promising, but means rework too.

Thanks a lot. If no other good ideas come up I will try your hints!

Cheers

Matthias

I took a look at the file. You’re probably not going to have much luck printing that with FDM/FFF printers. It’s much too delicate a structure to print without significant support. It would be the type of thing I’d print in an SLS printer. I’d give Shapeways a try, otherwise you’ll have to redesign it with printing in mind.

@Chayak We have quite a few SLS and many more SLA printers as well on 3D Hubs. Don’t send people away just yet :wink:

I think this can be done

Yes, but many of them are quite expensive. It’s one thing to support other hubs but quite another to pay over twice as much to do so.

I’m on it! Lets make these things work also!

Hi Matthias, it was great talking to you here at Euromold :slight_smile: As mentioned, you could try printing the octopus in an SLS printer on our platform as well!

@NikolaiK, @Spreadform, @rioprintocom and @reh191, can you recommend Matthias a hub that might be able to help with his print? Cheers

This looks to me like a design where 3D printing is simply not the best method of production. That’s not to say that it can’t be 3D printed or that 3D printing wouldn’t have a place in the production process. I’d 3D print a mould and vacuum form the actual shape itself from the mould. Perhaps 3D print a jig that would make cutting out between the octopus legs more accurate too. If you insist on 3D printing it from scratch, turn the design upside down and print on a delta-style machine.

Just my €0.05 worth. :slight_smile:

The design is nice , but as mentioned very fragile, it needs support and extra structures to stabilize the print also rotating the object 180 degrees should reduce support material. An SLS printer should do the trick but at what costs?

Hi guys,

I am really impressed to receive within 24h so many excellent tips!

Thank you so much!

@Pot8oSH3D

Will check how the vacuum forming works, never looked at it. Sounds to me like a process for making several copies…

@gabriela3d

Pleasure was on my side to meet you:-)

The concept of 3DHubs works well, so to make it even better I suggest two things:

* All the experts that help me to takle the design have maybe a printer or at least a profile here at 3DHubs but I found no way to find that out. Would be nice to have the name hyperlinked to their hubs, so I can place my next order to someone who helped me before…

* I receive a message that someone commented on my talk but to see the text I have to go to the website which is uncomfortable during traveling.

@Filemon

Did I understand right that you try to print it at the moment? So I am very curious if you will manage it.

All the best

Matthias

Hi matthias,

I’m interrested by your project, and i can print it.

You can contact me to talk about it.

I would definitly try upside down, HQ, with PVA support. I like this design. Can you show pictures of the failed attempts? I suppose you want it orange?

14

Hello Matthias,

the design of the part looks nice. As the other guys mentioned ist really not a design for FDM technology :wink:

From my opinion it’s a design for the SLS technology. We have some access to SLS printers. The technology is unfortunately more expensive. We could print the parts for around 70 Euros, just send us a message.

Best wishes

Hey Matthias,

Thought I’d give it a go and see how it came out. I had to scale it down to 120mm high. I’d call it a qualified success. The rough edges are due to a degree of “drool” from the hot end, when the flow of molten plastic is “turned off” between layers of each leg. I think this is probably unaviodable, although it can probably be reduced somewhat. It would need some trimming as a secondary process. It’s VERY delicate and I managed to break the sperical head as I removed it from the support. This was in ABS and it’s less than 1mm thick, so hardly surprising, especially considering the fact that my hands are like 5 sausages! I’m trying again, this time with Colorfabb PLA/PHA as I’ve found that I get better finish with that.

Hi guys,

thanks for your help and your tries.

Attached one pic from Form1+ try. From Ultimaker2 will follow next days.

@Pot8oSH3D

This is the best result so far, but still a long way to go.

@ManuelManuel from @rioprintocom

Thanks for the offer. Still hesitating to pay more than 50€…

@ImShogun

Prefered color would be white.

Hi Nacere,

see no other way to come back to you than through this talk.

What do you need to know to make it happen?

My boundary conditions are:

Price max 50€, color white, upscaling of model is ok but not downscaling.

Hi matthias,

You can join me by my hub http://www.3dhubs.com/lyon/hubs/lugdunum or contact@modellus.fr.

I use colorffab XT white and it’s ok for 50 eur.

Hi Nacere,

saw on your hub that you use Ultimkaker2 and most people here think that this is something for an SLS machine… so feel free to prove that it works but deal is only valid for reasonable quality print.

Thank you

Matthias
