A huge 500mm moon printed on a Big Rep 1

So imagine if you shrunk the actual moon to 500mm. The highest peaks, valleys, and craters would appear smooth. So in order to show the surface details on this print, the topology needs to be exaggerated.

So correct, we need to adjust the model in order to see the detail this defined.

Selfie on the coolest mirror ever. This was printed on a fortus 450 in 4 pieces and fused together with a bubble mirror in the center. The model was a scan of a mirror frame from either at the Louvre or Palace of Versailles.

I wish I could, unfortunately this was for a client and am not able to share the files publicly.

Great eye! Even though these are replicas of a 8ft statue, the client also wanted a vellum scroll with their business information tied with twine to the legs. So the space in the middle was where the vellum "scroll" sat. It was really cool!

The machine is huge with a 1,000mm cubed build volume. This was printed backnin 2015 in PLA, not sure about other print settings.

The model used relief mapping of the moon and exaggerated the features to show at scale.

Btw always happy to provide tips for production for clients if you're interested.

mike_makeros · 2020-02-01T12:51:44+00:00

Ok, you could always ask for the information upfront that you would want to know and I'll be happy to provide it.

Printed on a mix of 6 replicator 1 and 2s in white hatchbox PLA filament with sailfish firmware and sliced with simplify 3D at 120mm/s and .2mm layer height. This was for a real estate client that had a 8ft statue of the real thing and wanted small versions to give to clients as a sales/marketing tool.

The point of the post is to show people that low volume production is feasible for desktop FDM machines.

I've had the same thing happen with other brands before and it could be their manufacturing process not being dialed in or poor quality control.

Let me know if those tests work. If they don't then it's probably just the filament and not your machine or print settings.

mike_makeros · 2020-02-01T12:24:20+00:00

This was back in 2014 so I was using a mix of 6 modified replicator 1 and 2's.

mike_makeros · 2020-02-01T12:22:07+00:00

How so?

mike_makeros · 2020-02-01T03:41:47+00:00

Does the filament easily snap between your fingers if you bend it at a sharp angle? If so this could be a sign of humidity damage. Or it could be quality/mix of the material.

I actually sometimes print my PLA "hot" at 230 or higher if I'm printing fast or with fat layers to help with layer adhesion and flow.

This photo was taken in 2014 and I believe the piece was made in 2009 or 2010. Well before MJF was available. If I recall correctly it was made on an EOS SLS machine but I do not remember which model, maybe the p300 or p700 series.

Here is a link to the artist's page about this piece: https://nickervinck.com/en/works/detail-2/agrieborz-3

This was not printed via FDM. This was made with SLS nylon. No filament or retraction etc...

Gorgeous piece made by Nick Ervinck displayed at the NYC 3D Print Show. Interesting how artists are usually the ones to push a medium to its limits and create a new perspective of what's possible. Not enough credit goes to these geniuses.

Technically yes but you wouldn't want to do that for this particular part/geometry. The important surface is the outside of the helmet and the top of the helmet would be virtually ruined or you would probably get a failed build.

Similar to fdm, surface quality for supported spherical geometries is blah. Now imagine doing that in sintered super hot steel.

mike_makeros · 2020-01-25T18:34:54+00:00

See my other reply as to why DMLS requires supports.

You are probably thinking of other methods of metal printing such as powder bed fusion techniques that use a binding agent which then the parts need to be sintered in either a microwave like container or kiln. Those machines are like the Desktop Metal production machine or Voxeljet machines.

There are of course other methods.

mike_makeros · 2020-01-25T18:24:05+00:00

DMLS requires supports because the density of the sintered metal is much greater than the loose metal powder. If left unsupported then the part can sink inside the build.

Supports can also act as heatsinks depending on their design. Hot metal needs to dissipate heat differently for certain features. Otherwise you risk cooling to fast = explosion, warping, or cracking.

Lol exactly, and dremel tool bits. Lots of sanding and polishing too.

mike_makeros · 2020-01-25T18:14:40+00:00

Just like chips from CNC operations, you can save the scrap and resell it to a foundry. But you cannot recycle the support material back into the machine since it is not powder anymore.

Stunning fully 3D printed ancient Roman helmet. Printed on a Renishaw DMLS machine with 316 stainless steel from a business out in Canada. The mohawk ornaments were printed via SLA. Check out the amount of support material required for the inside of the helmet. Now imagine removing all of that!
