3D printer question

Hi,

So i’ve got something I would like to 3D print, small less than 5cm*³ *(x5,y5,z3
so approx 4.2cm³), but does have an intricate arrangement, the centre is a
celtic knot in 3D and I was wondering if there’s a minimum print
size/dimensions I should be aware of. I’ve looked on some commercial 3D
printing websites on getting designs ready for them, and seen on shapeways,
that the smallest part cannot be less than 3mm³.
Is there any dimensions I should be aware of when considering to print on
our one?
Also what kind of file type does it take? I have an .fbx file created from
Cinema4D, is it a .obj file I need, or will any 3D file type do?
Thanks in advance :slight_smile:

Rich…

Our 3D printer cannot match the resolution of a commercial printer. I
wouldn’t look to try and achieve any fine detail. A 5cm³ device is
possible but it really depends on the structure and detailing required. The
3D file format accepted by the slicing program (cura is what we normally
favour) is .STL.
Attach your file here and someone will take a look at it.

Cheers

Awesome thanks Alex, I wasn’t expecting it to match the same standards, I
just wanted to see what if it could even work and get to grips with the
procedure.

There’s the file in .fbx, it has a couple of un-necessary layers i.e.
subdivision_surface, inbetweens, rods and outermost outline, and would look
more like the attached picture in the end hopefully.On 24 July 2015 at 14:52, Alexander Lang alexanderlang1980@gmail.com wrote:

Rich,

To print a piece like that in one go is not possible IMO. I would print
the centre structure- the celtic knot with struts first. Although I would
actually print it in two halves and then glue those together. I would then
print the erm…ball sections again in two halves and then glue those
together and then stick the balls on the struts…and hopefully - Job Done.

I would get the opinion of some of the others though just in case I’ve
missed something.

OK that’s a great idea, when you say print the middle in two halves, i’m
now thinking something completely different…

Could it possibly work better making a mould and doing casts? Is actually a
dream of mine! Plus 3D printers take a while!!

“To print a piece like that in one go is not possible IMO.” -

Damn I thought this is where 3D printers would excel at, printing
impossible things!! In regards to 3D printing two halves of the Celtic knot
down which axis would you split?On 24 July 2015 at 15:19, Alexander Lang alexanderlang1980@gmail.com wrote:

That shape will be fine to print in one go on a sintering machine like
Shapeways have. I’ve had a few things printed there - where did the
3mm restriction come from? I can’t see it on the website for the white
strong & flexible material.

The main question I think would be how thick the ‘rope’ used for the
knot is - do you know the diameter?On 24 July 2015 at 15:42, rich op richop88@gmail.com wrote:

Hi Jim that’s absolutely great news, the 3mm restriction was specifically
for using steel: http://www.shapeways.com/materials/steel

It would be for jewellery, earrings/necklace, so that’s why I was looking
at metals.

“The main question I think would be how thick the ‘rope’ used for the
knot is - do you know the diameter?” - That would be the threads in the
celtic knot? I was just going to scale the model and make sure the threads
were over 3mm cubed.On 24 July 2015 at 15:46, Jim MacArthur jim@mode7.co.uk wrote:

I should clarify my answers related to using the 3D printer in the
hackspace and not shapeways…

size/dimensions I should be aware of. I’ve looked on some
commercial 3D

printing websites on getting designs ready for them, and seen on
shapeways,

that the smallest part cannot be less than 3mm³.
Is there any dimensions I should be aware of when considering to
print

on our one?
Also what kind of file type does it take? I have an .fbx file
created

from Cinema4D, is it a .obj file I need, or will any 3D file type
do?

Thanks in advance :slight_smile:

Hi Jim that’s absolutely great news, the 3mm restriction was specifically
for using steel: http://www.shapeways.com/materials/steel

It would be for jewellery, earrings/necklace, so that’s why I was looking at
metals.

“The main question I think would be how thick the ‘rope’ used for the
knot is - do you know the diameter?” - That would be the threads in the
celtic knot? I was just going to scale the model and make sure the threads
were over 3mm cubed.

I think the relevant restriction would be the “wire thickness”, which
is 1mm for a model of your size if I’m reading it correctly. Trouble
with Shapeways is it’s expensive to make a mistake - you might want to
upload it to them and get them to check it for you.

I’m thinking if it was 1mm for the wires it might not have much structural
integrity and potentially the heads could just snap off. And indeed
expensive to make a mistake! Thank you so much for your input both of you!

I can print one for you on my gooprinter if you want, though that is
limited to 45mm x 78mm x 100mmOn 24 July 2015 at 16:29, rich op richop88@gmail.com wrote:

OK, so I think I have the model ready for 3D printing, I’ve gone over the 1
million polygon limit for shapeways, is there any restriction on file size
or polygon limit for the goo printer?

Also is the offer still there to get this oozing out of some goo? And if it
is still there, is there a good time to come, and can we record it please!!

Hope all are well and had a lovely summer!On Friday, 24 July 2015 18:13:50 UTC+1, bob wrote:
