Flyplate5 is too thin to be 3D printed by normal machine. #2

Open kennithlv opened 3 years ago

kennithlv commented 3 years ago

And the Connex printer is too expensive.

kennithlv commented 3 years ago

Is there any way cheaper way to machine or print the Flyplate

floesche commented 3 years ago

Which type of printer did you use? Yes, the flyplate model is quite thin so it adds certain constraints to the manufacturing process.

We only printed it on Stratsys Polyjet printers so far. This part alone does not justify buying such a printer, but it looks like Stratsys offers a printing service on demand at https://www.stratasysdirect.com/ – that might be worth trying.

Alternatively, and we haven't tried this yet, you might consider a SLA printer. In our experience, you can print much finer structures from resin.

In the description at https://reiserlab.github.io/Component-Designs/physiology/flyplate we have documented that this was printed on a Connex printer. Since you opened this issue, what other information would you like to see there?

How can we help?

Is there anything else that you would want to have changed in the documentation as a result of this issue?

I have the same problem right now. So how can I build the Flyplate5? Thanks a lot.

Thanks for the feedback. Can you let me know what printer you are using?

kiule commented 2 years ago

Because we don't have a 3D printer in our lab, we are trying to find a printer service on the Internet. They give no information about the printers they actually use. They just refused to print because some parts are thinner than 0.5mm.

Thanks for your quick response. I am trying to understand at what point the order fails exactly: When I upload the model to the CraftCloud3D marketplace that we mention on the Production page, I get several offers – for example a rigid resin for $9.92. Is your order refused after this point?

Thanks for your response. Well...I'm in China, so I didn't try to use CraftCloud3D (in my experience, it means a very long waiting time and is much more expensive). As a result, I turned to some local printer services. Because I'm not so confident it can be built, I always firstly asked them whether they can make it, and the answer is always the same: it's too thin. I'm lucky to find that CraftCloud3D can build this in USA and send it to China and to me. Perhaps I can make it by this ways.

Oh, I didn't know where you were looking for the printer. Apologies for the current bill of materials, the links are always a bit US centered, but whenever we find out how to acquire components in different parts of the world, we would like to add that to the repository.

If you are looking for a printer service, try to find one that offers "Stereolithography" or SLA printers. They are more common than the Connex printer we used. The SLA printers are often used for printing game miniature figurines, so you might get lucky searching for providers of table top game equipment?

In any case, if you find a provider, please post it here – and let me know if I can help.

Apparently, PCBWay is now offering 3D prints. They are located in China and offer SLA.

Thanks for your advise. I have tried to print Flyplate in the past two weeks. Two roads I tried: PCBWay and CraftCloud3D. I submitted Flyplate5 to PCBWay to be produced by both 3d print and CNC and the orders had passed the review. But after I paid the orders, the engineers of PCBWay emailed to me, noting that the Wall thickness in the design had not reached the limit (0.8mm) and asking me to change the design. So this way is unsuccessful. Although CraftCloud3D has no direct service in China, I contacted to a graduated PhD from our lab who now work in the US. He would help me to received the printed Flyplates and then mail them to China. Following the picture you showed above, I printed them by grey Rigid Resin and happily found that the manufacturer is Cheetah Farms (if they can build the plates for you, they should also print them for me). However, when he received the printed plates, he found that they are broken! I'm not sure whether this damage happened during the production or during the delivery (I have emailed to CraftCloud3D but have no response till now). I really understand that the wall is too thin and easily to be broken, but if you have tried to print them, this way should also work for me. Have you really used CraftCloud3D to print Flyplate5? Did I use the wrong material or do anything wrong?

Hi, I have successfully made this using CNC machine. You can contact me.
