Dear 3D Printing Fanatics - which Trade shows should we go to? Any recommendations, or any missing (and why?)

Greetings from the CNRS lab in Toulouse, France :)

Duly noted

Good to know! For me, integrating electronics and other elements (flex, rigid, other materials) matters a lot, and even parts like chips and connectors.

This is the future imho - far more than just 3D printing, but total harmonious integration. That’s our vision

Yup - hard to improve on the essentials … but what makes a format useful is how many use it, not necessarily how good it is. Ex: VHS v Betamax

Heeey I used to work there before we got bought by Stratasys. I wrote a lot of the content and managed the competitions, etc

Yeah very helpful! But handling multiple files is a bit of a different story, or colors or functions. “Just Hit Print” gets more complicated … “more models, more problems” ;p

Yeah I like STEP as well but never considered it a AM format. I missed the memo on 3MF but recall AMFs big debut in the early 2010s

Should I include STEP and 3MF?

Is anyone still using STLs? Shimmy will still support them but for Multi-Material 3D Printing, processing them is painful. AMF is better but what other formats have become big hits for you?

Very much like a hotdog with the ketchup/mustard colors (standing in for Magenta and Yellow). None of the vat Z heights or XY offsets were calibrated, but it didn’t fail either!

Just wanting in terms of color management! That’s for another day #color #3dprinting

But here’s a preview - literally - to hint at what we’re testing. This was taken from our interface

Am 3D Printing with ketchup and mustard. Cannot provide advice on taste or texture - but I can tell you that yes, that is two of a four vat resin printer we built ;)

Your approach is certainly a hybrid like mine. You made the mask using a liquid resin (or film) then laser-ablated it, yeah?

Oh I’m talking about another printer prototype that print Copper + Cyclic Olefin Copolymer. We can even introduce fiberglass to match the CTE properties. Have also considered ceramics as well, which are easily printable as a substrate.

We have a prototype machine that works on a similar principal - same price but infinite layers and even bulk metal printing.

I’d love to share our experience and see what you’ve got.

Am assuming you’re using a laser? Maybe milling but i doubt it.

Not unreasonable, but decent PCB mills can do two layers for 1/3rd the cost. Iirc a BotFactory SV2 can do 4 layers or more for about the same price, plus pasting and assembly.

What they have issues with is the conductors are not copper, and the materials aren’t great.

What are your PCBs made of?

What’s the base cost for a machine that makes two layers?

I have worked in PCB Printing for desktops in past and present roles. It depends on what the final result is (ENIG pads? Copper thickness? Substrate?) … also is there a pathway to 4/6/8+ layers?

I’d be curious to know if you’re looking at soft and hard materials to be combined for your 3D prints… might be something we can print!

We may have a solution to your issue :)

We are a multimaterial 3d printing company and the CAD software exists. You can model virtually anything with almost CAD tools so idk what this person is talking about.

There is a field of “DfAM” or Design for Additive Mfg … and those tools don’t manage MM3DP well … yet!

What lies beneath a four vat 3D printer … hat tip to the temperature sensor and stepper wiring in their support roles

A small sample of the exciting stuff we have in the pipeline! If all goes well we can share everything we can do with our “Quad” resin vat 3D printer ;) #3dprinting #innovation #fourmorevats

I read a review of Neuromancer that described the world William Gibson made as “a place I’d like to visit, but not live in”.

What do you call that sort of Future?

Revising the User Manual to make it more enjoyable and helpful

It’s a real pity - I have an excellent bedside manner

New blower blows 3D Prints away (shout-out to Nectar Labs for the logo, our R&D outfit)

(2/2) I have high hopes to 5x printing speed using this air knife with the higher pressure/volume blower. A bit annoyed we stuck to the earlier design but it was COTS versus custom made (or riskier). But that’s what Research and Development is all about! #R&D #3dprinting #prototyping #innovation

(1/2) Drying prints very quickly requires a great quantity of air under pressure. We started with air fans and found them lacking, moving onto air knives that were inexpensive. Plastic (e.g. ABS) cracked over time, so we got these pricey stainless steel parts and then aluminum slot-pipe designs.
