Hi All,
   After trying many different powders I've Finally got a powder that makes a
really good parts using 600 dpi setting. the finish is very close to that from 
Zcorp made parts. Actually it's so good that I need to redesign and rebuild the
build bin actuator becouse it's not accurate enough(have some play side to side
when it moves up/down).
   Now, good finish doesn't come cheap, the gypsum mix I'm using is kind of
expenssive around 16 usd/kilo but much cheaper then the zcorp stuff and it's
sold in 50kilos bags only.
I'll upload pics to my blog after fixing the build bin actuator.
  I've spent lots of time on this project and spent a good amout of money on it,
so I need to get back some of it or keep my latest finds to myself.

so here is what I have in mind;
Options:
  1- To sale plans to build one
  2- To make a board to controll it
  3- To sale the powder(wondering if I can be sued)
  4- To sale a kit (out of question I can be sued for shure)

1- Selling plans means that I will have to rebuild the machine to use standard
easy to find parts or maybe make them and you can get only from me(like the
cheap linear rails)

2- Making a board that the parameters can be changed by serial port(no need to
install Bascom) with 3 axis stepper motor drive or without it ( you will need to
buy your own drives).
the board would cost around 100 USD without drives and around 200 with drives.

3- This is a special powder mix to make usefull parts using only a mix of 1/2
water 1/2 ink on cartridge and 600 dpi setting(can print usefull parts on a
regular lexmark printer) but uses one or more components of the patented powders
but not all of them.

   A few notes:
  To get good printed parts all of the components that makes the machine needs to
be reasonable accurate, this includes;
linear rails needs to be straight and flat, spreading roller needs to be
concentric( no more then 0.001" TIR we are dealing with a 0.0039" layers) and
you need a good quality acme leadscrew.
Also You will need to replace the MDF top by either a aluminum plate or CORIAN
as it's the base for the hole sistem.
please take this as a advice before planning to build one.

Open to sugestions.

There is no hard and fast rule about how much difference is needed to call a
formulation "new."  Your best bet is to consult an IP professional.

I am not a lawyer, nor do I play one on TeeVee.  I just know that when dealing
with something as complex as IP law, there is no substitute for good
knowledgeable advice.  Which I have received at fair cost.  It is much more
expensive (in time and money) to "wing it" or follow amateur advice and make
costly mistakes.  You know 3d printing - concentrate your efforts there and let
someone else do the hard work to protect your developments and inventions.

Donald.

Hi,

To let you know, if the mixture is 30% different from what somebody else use's
then your in the clear as far as a law suit being won against you. But, that
does not mean the law suit would not be filed and just drain you of money until
your broke.

Recouping your money in regards to R and D is expected, that is how businesses
are built, that is reality. But, just because you get the results that your
looking for does not mean some else will get them too. You need to have peer
review of your design some how and have others your mixture. That does not mean
your giving away your rights to the formulation of the mixture, this is what
non-disclosure documents are for. Just remember though that a non-disclosure
document is only as good as the amount of money your to enforce the document in
court, a.k.a sueing someone for violating the agreement.

Selling plans is a good idea, simple to copy and make nice looking documents.
Selling the control board is simple enough too. Selling the mixture as I stated
above can be a little in the grey area, if you get my meaning. Making a kit and
selling is fine too, just because your using a pre-fabricated printer as part of
your machine does not stop you. The person buying the kit just goes out and buys
the right model lexmark printer and the kit contains the modication documents
and parts or how to make the parts.

What you are doing is legal, your not stealing anybodies super secret company
formulas or anything, your are filling a void and there is nothing wrong with
that.

I agree with Kevin. Plans and controller are no problem but powder.
The point is this: I also found a special gipsum company. This company
can produce the same powder like Z-corp and the price would be 2 to 5 %
from z-corp price, but they told me, they can not sell it, because
patent law.
But... and that the point... they can sell this same powder if they
declare it for a total different, non 3DP, applications. For example
like light weight gipsum for art repair. In this case, there is no
patent conflict. I hope you understand what i mean.

  actually it's a certain dental plaster brand that works better then others and
it's not even white it's pink.I've added a little of pva to it.
  the problem is that the pva is sold in 50kilos bags
  the idea was to buy the pva ,mix and sale it by the kilo, as it would last for
over 5 years for my own use.
  Maybe it does not do a good job on zcorp machines becouse I've mixed it to work
with the low water volume drop out from a lexmark printhead.
  Just to make it clear, I'm not trying making business here ,there too many
people asking for more like the board, plans, powder etc...
  I think asking to make some money back enough to cover for my time is right
since I've got nothing for free .
  Maybe I'll make a new board and post to the group and if someone don't want to
make it on theyr own then they can buy it from me.
  making a kit is out of the question becouse it would need lot's of my time
dedicated to it maybe I'll stick to the plans as z corp can not sue me for that
after all I'm using a regular desktop for this.

Yes, I think you should post your formula so others can improve it, or adapt it
to other uses.  Of course, as you say, people may want to buy the powder from
you if they don't want to make it themselves.

One question:  did you manage to find PVA that was fine-grained (80 micron or
so), or is it coarse, like Elvanol or Mowiol?

Why not keepto the open source mantra and raise money in other ways. A possible
way would be to add up current costs and costs for a new version of your
printer.

Then, use a service like http://www.kickstarter.com/ to raise the necessary
money for development. Offer plans for a certain donation level, partial parts
kit for another donation level, and a starter kit for the top level donations.

If, for example, each individual on the list donation $20 (or more) to your
cause you could raise up to $14K. More than enough to develop the hardware and
enough to, perhaps, hire another individual(s) to write software based, say, on
the RepRap software. I am sure there are even more individuals off-list that
would love to contribute.

Also, you may consider bringing other collaborators from this list that can add
expertise to your next project.

I would be happy to allow you to post an advertisement as well and would be
happy to be the first to donate. However, I would like to encourage you to keep
all information open source within the public domain.

Lots to think about!

I think, if the following isn't illegal, selling plans would be great.  I for
one will surely be a buyer, if sensely priced.

To offer different stages of plans from say novice to expert, aka, complete to
full on find and build based on plans, would be taxing on you but you might find
it as a great business.

For sure detailed flexible plans at minimum.  Quality parts in the areas you've
already mentioned.  I would like to see plans for the electronics.  Parts list,
schematic, pcb layout.  These can be done easily using software if ya know what
you're doing, then people could buy the parts from their supplier of choice and
build if that's in their skill level.

My opinion only.
Great to hear all your work is about to pay off.

   Donation won't work as I foud out. I had a request on my blog for a donation
to keep the project going but no one offered any donation not a sigle dollar
bill but there is over 70 followers on it.
  plus it looks like I'm bagging for money.
  I'll stick to the plans and pcb boards. the pcb board will have a 3 axis step
drive and the parameters can be changed by a a therminal program or maybe just
using the lcd screen think of it as a plc with step motor driver. I'll post the
pcb and hex code to the group if someone wants to make on theyr own.
   I'll be selling the powder too since I do have to buy the 50 kilos bag after
all it's just the dental plaster if you know what I mean plus it's pink not
white but one can change the printed part  color by using blue ink for exemple.
   I've made a few prints with the new powder so it's a little to early to say
it's the missing link but 2mm thick  walls by 10mm high have survived removing
from the powder bed.also I did print the same statue figure and it came out with
really nice finish, I was going to post a pic to the group but I mess it out
when infiltrating with cyano(only had a thick one at hand) I will print a new
one and take a picture for comparation to the old one and post to the group this
week.
  I'will offer some critial parts like the roller assembly, a better linear rail,
gears,pulleys and belts  also I'll have to sale the step motor that works with
the standard printer drive not easy to find.
   Now, enough talk and let's get back to work I need to think a little more on
how to improve the machine accuracy without braking the 1K budget to build one
by yourself.

I had the pics on my computer so I just uploaded two pics to my Album.
  As I said on my previus post i didn't do a good job on infiltration. Also parts
comes out clean from the powder bed, I just used a air compressor to blow out
the excess powder from it no picking tool is needed anymore.my hand hurts from
tap myself on the back :-)

it was like half of the money spent buying parts and the other half on
tylenol. :-)

  Yes it's a fine grained hard to get PVA and dental plaster, I had some coarse
grain PVA  that I did ground it to a finer powder for my initial testes you can
do that if you can't find a finer grade.
  Actually you don't really need to add PVA to the dental plaster IF you play
with the ink on the cartridge( mix your own formulation to controll how the ink
gets absorbed by the powder) but as I had gone thru  about 8 print heads  trying
some stuff on it I gave up on it(it was getting too expenssive to play with it)
  Actually no one wants to talk about how a inkjet ink is made it's kind of Black
magic they will not even talk how to properly refill your cartridge. After many
trials I've found out that it needs  a vaccum chamber to remove the air from the
ink or it will fail to print properly. As I had a small vaccum pump and a Jar
that was easy but not before lossing half of my  hair trying to figure out why
it prints when I take it to the store to be recharge with ink and not print 
when I recharge it using the same ink and a syringe.

pc boards would be the best for selling. Speaking from my point of view, I can
machine almost anything, but electronics are a dark art to me. Would you be able
to do some sort of service bureau work to recoup some of your costs? Just a
thought.

  I'll have to work on a new board and firmware also I'll be using a better
microprocessor to handle the bootload and lcd I've being thinking about using
atmega32 as it has lot's of flash and extra pins to add new features, the step
drives will be based on the a3977 chip as I've being using it for a long time on
almost every thing from routers to cnc plasma cutters and on my own 3d printer.
  I don't know about a service bureau as I've built it for my own use and there
is a service bureau on my city already.
  What I really want is to get funcional parts out of it, I've heard that the
plaster can be infiltrate with epoxy resin for that, I will do that when I get
some free time to try.

I agree, the goal should be to get parts off the machine.  The machine should
not be the sole goal...hey, that ryhmed.  An affordable, buildable machine
should be part of the goal of course.  Lets use the machine for it's intended
purpose....Reprappers are too much into their machine, no offense
anyone...please keep cool!

Thats all not useable! And with a normal inkjet cartridge it is
impossible to print bigger parts. The ink will be empty after a few
layers. And refillig is in any cases hell. Thats not a solutions, thats
toys..
Have you ever test one of the HP business Inkjet series? You find each
day those printer on ebay. For me, its the perfect print system for 3DP.
No trouble with refill, because it have external ink canisters inside.
And also no trouble with ink heads. They are cheap and easy to change.
And it is  the same head  z-corp use. Why do you thing z-corp use it?...

PS:  Mowiol for example, sell on stock two PVAs types as  fine grained
(round 80 micron).  But it is still to big. 20 to 40 micron is much
better. But if you pay more, you can order each kind of PVA as 20 -
40micron fine grained, special order.
