it seems the people at Morf3D are pretty serious about quality control :

so happy to know that they are (still) working with SASI

at least they have hope themselves
https://www.defenseworld.net/2022/05/04/insider-buying-sigma-labs-inc-nasdaqsglb-director-buys-15000-shares-of-stock.html
the relevant section is that they use Velo3D printers
which have their own, pretty advanced, in-process quality monitoring.

and do you actually do the comic book guy voice from the simpsons?
promising results on the closed loop application >
https://www.materialise.com/en/resources/software/whitepapers/real-time-control-loop-study
seems like a good experiment, good control with the Ct scans
some real integration there between MCP and printrite3D
interesting notion that partly remelting of a previous layer allows repair of defects
to me this also kinda suggests that optical surface monitoring will not really have an advantage to meltpool monitoring for these kind of defects
you’re really on top of things, materialize about the only partner
that doesn’t produce it’s own printers
market seems to react appropriately.
it’s really just a rehash of previous agreement with
DMGMori. It’s good news for sure but already factored
in. No reason this ‘new’ deal would lead to more sales
compared to the last agreement. PR3D remains an option.
I’m kinda happy the market reacts normally.
these guys also seem to be interested/involved with sigma labs
https://www.3d-mectronic.com/
what do you mean exactly?
Which awareness pieces are you referring to?
sigma labs receives an ASME best-in-class award
https://event.asme.org/AMtechforum/AMnews/First-AM-Innovation-Awards
it seems to be mainly for plastic parts.
another interesting thing is that Ruport during recent presentations
either doesn't mention or seems to downplay the association with Materialise. Did someone else notice this too?
as i’m sure you have some proof of this
so, no german connection for sigma labs?
looks interesting,
the link doesn't provide the text you mention though,
do you have a link to the report you cite?
presentation of a research scientist at VTT who is validating PR3D
https://mfg40.fi/wp-content/uploads/2020/12/VTT-Reijonen-process-monitoring-LUTseminar.pdf
from their comparison to optical tomography and CT it seems that PR3D might be more sensitive to defects than optical tomography, although simply measuring time-over-threshold (ie how long is the part too hot at a given region) is seemingly just as predictive as PR3D.
anyone some ideas?
the only thing it could possibly mean is that there would be less requirement for printrite since binder jetting does not have a melt pool
huh, has been a year again already?
finally, a mention of sigma labs :)
no, seriously, it's good that these guys are taking the fight right to sglb, the competition is now formal and management will have to become more specific about strategy, projections and technical comparisons of the different systems.
yeah, i don't know, i'm sure cameras can keep up. As for now they can see swelling, offsets in height, spatters. All those PR3D can not detect.
And they claim they can see porosity being formed as well.
There's a nice paper on it >

promovideo, nothing new
thanks visionary for keeping us
posted!
in time you would guess most intricate parts would be produced by 3D, sheet stuff would be stupid, i'm just wondering how they come up with this 2 billion addressable market.
which would be quite troubling, something like that does not instil a
lot of investor confidence
would leave a lot of room for cronyism trading
aight, thank you maxinkuckee
when and how do you get to vote, do you get contacted?
visionary, thanks for digging that up, very useful information.
I seem to remember during their 2019 period they saw a signifcant dip in their software sales that they saw as a temporary event...
looks like Velo3d has already though, closed loop control and all, more complete set of parameters next to thermal melt pool monitoring
if the market for IPQA will indeed be billions within two years, as NNW just mentioned :), they might be well off making it machine agnostic and going that route
if only we could buy their shares...
ViperSteve, thanks for the thoughtful comments!
I just hope the TED and TEP have some real added value to calling imperfections, otherwise anyone can show up with some sensors to measure melt pool thermal.
any chance you have a link to the update by Ruport on that?
guess i missed it..
'Our IP portfolio has a virtual moat around the entire quality control industry for additive manufacturing'
this is a quote from the shareholder letter in 2019
Now, what is the value of this IP if Velo3D can just go ahead and use optical and thermal sensing of the melt pool in such a way that they have a working AND closed-loop in situ QA software?
https://www.digitalengineering247.com/article/velo3d-the-most-advanced-metal-am-system-youve-never-seen
looks like materialise remains interested in applying melt pool monitoring
https://www.materialise.com/en/blog/takeaways-masterclass-metal-3d-printing
good to see that the PR3D technology allows repetitive, almost identical, production of promotional matter.
TedJ, thanks for sharing your insights!
TedJ,
what do you make of Stratonics also using
TED and TEP parameters in their MPM (noted in
the Dec slide show competitors table).
Shouldn’t they be unique to PR3D because of
patent protection?
Melt Pool Monitoring – monitoring the weld pool
In order to have a better overview of the LMF process in the TruPrint machine and to be able to optimally evaluate the component quality, you can take advantage of the Melt Pool Monitoring product for the TruPrint 2000 and the TruPrint 5000, alongside the Powder Bed Monitoring function. Melt Pool Monitoring monitors the weld pool of the laser metal fusion process using sensors. Take advantage of a detailed quality check and documentation, layer-by-layer. This enables you to detect any process deviations early on, including during series production, and, if necessary, visualize areas of the component that are critical. These key figures can then be automatically compared with a reference build job to monitor the stability of the process. When using several lasers, you can also monitor all of the weld pools in parallel with ease.

there really shouldn't be any technical reason why this shouldn't be possible for any melt pool monitoring system, and i'd be disappointed if sglb would try to make a big deal out this
Trumpf did develop their build processor in close collab with Materialise...
https://www.materialise.com/en/software/build-processor/trumpf-build-proccessor
and sigma labs and Trumpf are both in the Fraunhofer IAPT association
i like to be optimistic too,
but since MZ is doing the PR i feel like they use bloated language in their correpondence...
Also, it appears that VTT has exactly 1, low-end, one laser, SLM printer in their facility...

you know, this is kind of interesting,
the last three times that there was a pre-market uptick in share price,
this was because of exactly 100 shares traded.
Any ideas what this could be? MMs trying to fake a rally on the cheap to dump some shares?
Could this person or instance be identified in any way?
thanks
thanks Jackle,
very happy they are starting to address the competitor landscape in more detail,
would be great to hear their take on those high speed camera based methods by flightware also though
cheers
