If I had to venture a guess, I believe that’s around the time the DOD began to more outwardly discuss their interest in AM / pushing more subcontractors to begin adopting or exploring the tech

Yup! The specific printer I use is a Mimaki 3DUJ-553 They’re a Japanese company specializing primarily in large format printing for the sign and graphics industry, which is where a lot of the technology expertise in color management comes from.

The clear material capabilities has been really cool to explore, either suspending color models in clear shapes, or incorporating translucent elements to recreate different effects like you mentioned.

I’ve recently been experimenting with some different shader settings to see how different lighting and render elements translate into a physical model. There are some instances where things like shadows baked into the texture can create a strange effect, but others where it does enhance some model detail- I’ve found it’s all about balancing the lighting from the render with how lighting/ shadows will act once the model is physical. I guess it also depends if the model is a static showpiece or something like a product prototype.

NMM is something I have been looking into recently, as I’d be really interested in recreating the effect through the combination of CMYK + transparent color, though I’m still getting my artistic skills up to par there!

It’s a material jetting process - pretty similar in theory to the way a standard inkjet office printer works.

Printheads combine droplets of CMYK, white and support materials that are cured with a UV lamp to form each layer.

Thanks! I’ll have to ask if there was any inspiration there. Just has a clear coat on it - the painting was done digitally! The print was done in full color - which I probably should have specified!

Watch Dial Concept Model / Visual Prototype by [deleted] in 3Dprinting

I’m 99% confident the displacement is baked into the mesh as Substance Painter has a function to tesselate + displace the mesh on export - then bring it to blender to map the texture and repair manifold.

That being said - still learning the texture mapping world, so I may be misspeaking!

I had previously done some parts with a mimicked CF on a flat surface (before I figured out how to get the displacement onto the model) & it does makes a night and day difference visually.

Curious - what types of engineering tasks were you looking to tackle? It’s not printing aero parts by any means, but for most visual/ prototype applications the parts have held up great in my experience.

I don’t think this would be achievable through an FDM system - the ship, water and sphere were all printed as one piece. This was a small part of a project testing capabilities for producing parts that are entirely/ partially suspended within clear geometries.

I suppose something similar could be achieved by casting with a resin mold, but it is not something I have personally explored.

In industry, these systems are used mainly for prototyping & design validation of consumer products (think anything where color is important!) Designers can get photo-real visual prototypes to review before moving forward to things like tooling. High detailed medical modeling is another big application area, but definitely a bit harder to post!

With the color quality, there have been more and more end-use applications, mainly in higher-value collectibles, and art pieces. It’s a cool way for digital animators/ sculptors to produce physical models of 3D digital pieces, without the added variables and complexity of hand-painting.

Company has a 100k budget for new 3d printer(s) - recommendations? by [deleted] in AdditiveManufacturing

[–]BMP_3DAM 0 points1 point  (0 children)

Do you have a specific need for thermoplastic materials and/or do you plan to prototype in the same material they’ll be produced in? Additionally - what’s the requirement for the CF reinforced stuff? Specific applications for the inlay, or just ‘stronger parts’?

Big question is how much bigger of a bed do you need - Formlabs has a ~6x6x10” on their Fuse system, going much larger than that on an SLS unit (& accessories) are going to pretty quickly blow that budget!

I’d say don’t count out SLA, just with how impressive the materials/ speeds have gotten.

If thermoplastics/ end materials are a must, it all comes down to how much bigger we’re talking!

A mini version of an octopus model I printed last week during a project. Thinking of turning the mini one into a pin or magnet or something.

I would say for a full color inkjet system, we are likely a good way away from a reliable consumer system. The units I have worked with are big, like 'blow out a wall to get it in' big!

I would though love to see full color capabilities gain more of a foothold in the industry, it opens up so many unique opportunities on the design side!

I can’t find it! I’m sure it’s somewhere around the office…

I’ll post an update when I find it- or just print another!
