Hi Sean, seams like it would be best to print it in SLA Plastic or Plaster Powder printers like our’s, Try our hub in NY and we will be happy to help you.
Cheers

Love this model!
On FDM I think the main issue would be support on the inside of the “bulb” near the top where it starts to become near horizontal. I think that you’d need to add a column up the middle and possibly branch out with some custom support. That is FDM.
All of those tiny holes might be another challenge, but I’d need to test a small section and see. It will certainly take a lot longer I think. What is the wall thickness of the main structure?
Also what particular challenges did you have last time with the other hub?
It’s useful to know which areas are critical in terms of finish. There is another obvious overhang but I assume that will be largely hidden when fitted in place.
Doing this on an SLS printer is probably going to get you the best results, but at a cost. What sort of delivery time do you have in mind?
Cheers,
Greg

Hi Oren,
How much would that cost including shipping? As I am in the UK and on a reasonably tight budget (student project and all).

Hi Greg,
Glad you love the model!
Basically it printed pretty darn well until around 98mm and was printed upside down for support purposes.
This however the fell over due to some retraction issues, as I am not au fait with printer settings etc. I couldn’t justifiably explain it.
Thanks,
Sean
Good to ask… Before my hub was running, I got an stl printed for me (not via a hub) and I paid £40 for a rubbish print!!!
Wow, it’s nice. What scale do you want it? As mentioned below, the holes might be a bit of an issue, but it depends on the scale… With FFF, It might take a bit of time to make sure all the holes are clear afterwards.
Is it a light fitting? At 100%, that makes it 17.8cm tall? If you want, I’ll print the first 5cm or so tonight to see how the holes come out. (FFF).
Regards
Cris.
Yeah I have thought about using the Form 1+ printer, however I need it to be this size for both aesthetic values and for the size of the bulb I am using.

Actually better to print upside down to minimise supports… I’ll print a bit and post a picture…
I am going to attach an image of the previous print 
This was the print last time. Printed upside down

If printed upside down you will get the poor surface on the outside (FDM specific point), If you can get it printed the right way up, the overhang is hidden to some extent inside the bulb. Depends again where the finish is critical, that’s why Hubs will often ask so many awkward questions about your product
Ahh that’s why. Do you think a dissolvable support would be an option?

The part you have showed doesn’t look bad (the holes look pretty good at least)
Hi Sean
I just had a look at that file on my objet and the way I would go around this one would be to print 2 halves which would come together afterwards.
If the pice is based on a total height of 180mm tall you are looking at a fairly expensive print due to the nature of the shape. It would need a lot of structural material. Saying that though I’m quite confident that I could make this print look pretty tidy.
If you have a peak at my hub’s images, I have printed fairly delicate shapes successfully before.
Let me know if you want any further advise.
Happy to help.

Yes, I think it may well be an option. I can’t do that myself though so can’t comment further. I was thinking more along the like of suppport that could be broken off and would look like a tree -possible in 2 halfs but it would probably take quite a lot of thought and maybe some experimentation to create that support in a way that it both works and can be removed and extracted afterwards. An interesting challenge
The holes were alright, a bit stringy but that is probably to be expected.
It however failed at that height. Hence the questioning
There’s an image of how I would print the 2 halves…
Ahh yeah that would join nicely.
Hi Sean,
I’ve just analysed your model for our Projet 3500 HD Max in blue acrylic and it’s possible to produce in one piece as designed but the cost is approx. £650 plus vat for XHD mode (0.016mm layer) or £425 plus vat for HD mode (0.032mm layer). If that’s within your budget, don’t hesitate to get in touch.
kind regards

Blimey! That’s a lot more expensive than I thought. Thanks for the quote but it’s well outside my budget. Sorry.
Make sure to link to your Hub next time 
We’re all about keeping it all within one platform,
Cheers
