I know this is a little off topic, but how do you think the DWS printers
separate the part from the resin tray? It doesn't look like a slide or a tilt is
going on.

All the best,
Jason

DWS (Blueray laser)Does a lift off and a dip down in the resin. There is no
tilt/slice/vibrate.
It is simply up and down. Up and down with a DLP and you end up under the
En....tech patent.

Cheers!

Their VAT is Solid Acrylic/Perspex/Plexiglass/Lexan...
It does have a coating of some sort ( PDMS? ) that goes milky white after some
usage. and you rotate the VAT 90 degrees- that way you have 4x the uses of the
VAT.

I believe there is an exception: building a patented item only for proving the
patent claim. ;-) Not even universities are allowed, although it is very common
there. In the jewelry biz there is a thing called 10% - make it at least 10%
different and it is a new design.
You can say you were inspired by...so and so.

hello dears
i have z450 3d printer from zcorp, and suddenly with no reason it doesn't start
up and the lCD illuminated but blank, when i connect the electronic box to the
monitor, it gives the bellow error message:

"warning kernel.346060: application: ELCFU.EXE not found on disk.
fatal error kernel.146040: nowaithost specified but no application present.
setting run mode to WAITHOST.
Ready for debugger commands."

can anybody help fix this problem?
Thanks for your co-operation

Hello Group!

My name is Matthew and this is my first post.

I want to use a dlp 3dp with water clear resin but I hear that it is difficult
to control the way that the light is projected into the the resin bath. Does
anyone know any detail about this?

Also, since dying the resin is recommend, I was wonder if there is a dye that
changes to clear once it has been exposed to uv light for an extended amount of
time.

Any information is helpful

Thank You!

here are two examples of what I would like to achieve.

OK, one thing to remember is the PTO handles both design patents and
innovation
patents.  The innovation or invention patents involve claims bearing on
procedures,
processes and functions.  The design patents involve design elements
like shapes,
colors, fonts and similar things.  So, the Nike "swoosh" and the shape
of the
old Coke bottle are design patents, and the claim is the physical object.
Defending design patents is very different from the other type.
Jewelry patterns would also come under the design type.

The Objet printers have an advantage in this because they only spray out resin
which is to be cured (ie: part of the part) into the area their lights can hit. 
In the case of DLP or SLA, there's a whole lot of 'bystander' resin in the line
of fire.

Not sure about the other company's tech, but what I can say is that we'd need a
transparent UV blocker to make it work with projectors.  I'm pretty sure such
things exist, since you can get UV-blocking acrylic which is still clear, but I
don't know what they're called nor how to acquire them.

Yes, I used the wrong word, utility is the one.  Up until the comments
about 30% difference came up, yes, that's what I thought, too.  30% of
an idea has no meaning, so that's when I thought to mention the difference
between utility and design patents.  But, clearly the suit over the 3DS /
formlabs situation involves a utility patent, and 30% change of the
basic concept of the 3D printing process doesn't, at least to me, have
any definable meaning.

Really, only what the judge and jury think about the arguments given make
any difference, the rest is speculation.  And, suits often turn out to have
a big surprise.  Unfortunately, we may be lucky to even have an answer
by the end of 2013 on this one.

Hi,

If that was the case ever software company in the world that use's Microsoft's .NET platform for making their software could sue every other company that use's the .NET platform because you would be infringing on each others internal code in the software.

I have lived and make money with my patent attorney, if you don't want to listen don't. Go play attorney and get your butt handed to you.

I built machine's that according to you Bertho infringe on Zcorp and just about every other machine out there... I haven't seen one lawsuit, I have two patents with a third coming. So, I think the money talks and the rest walks.

I've tried to get this point across and hopefully people think about facts.

I won't post again about this subject, amateurs.

Kevin I.

I echo Mike’s comments below.  Nothing about %.  Read the claims extremely carefully and understand them.  That is what counts.

I am not an attorney but I do understand a bit about U.S. patent law as an inventor and as one who has had to defend against infringement claims. The bottom line is that  "Claim Language" is binary; you infringe or you don't infringe particular claims. You make direct comparison of the claim language with the alleged infringing elements and demonstrate that it does or does not infringe. The patent you download only tell part of the story however, and there is a file wrapper in the patent office for each patent, and that carries the back and forth with the patent examiner over the meaning of claims, clarifications, etc...  and may in fact may narrow the interpretation of a claim significantly. This can be done by limiting field of use for instance or arguing why your claim does not mean the same thing as some previous patent claim. Percentages are irrelevant, and I would steer clear of any lawyer giving that advice.   --- On Sat, 11/24/12, Kevin Impson <internetgiest@...> wrote: From: Kevin Impson <internetgiest@...> Subject: Re: [diy_3d_printing_and_fabrication] Re: patents?

Do someone can offer for me original or additional material for Z406 3 Prototype
printer..
any help and offer is highly appreciated..

Yes, if formlabs/kickstarter can get the judge to throw out the whole
suit due to
3DS' claims being frivolous, it might end quickly.  But, I think most
judges are
hesitant to take such a decision lightly.  there certainly are some
suits that are
just plain frivolous on their face, and do get tossed like that.  But,
somebody
non familiar with the topic at hand needs to get educated on the
terminology,
what is being claimed and whether the defendant is making anything that
actually infringes.  I don't see a judge throwing this suit out quickly, but
I guess it depends a lot on the briefs their lawyers submit.  If 3DS has
mediocre lawyers, the judge might find a lot of waffling in their briefs
and be steered right to where they are trying to bamboozle her.  We can
hope!
