It's easier to design it from scratch with individual numbers, than modify the CNC files.

Ja danke für den Link, Spritzen und Kolben hab ich schon. Das Volumen für die Spritze ist maximal 5mlheld, also alles recht klein. Ich muss die Pumpe a bissal anderst bauen. Sollt ichs nicht hinbekommen würd ich mich gern nochmal bei dir melden. Ist das ok für dich?

I'm located near Frankfurt/Main ... shipping shouldn't be a problem, but getting time to build a new one could be harder to achieve 8-)

Do you have some specs/dimensions?

I've ordered the cartouches at Globaco - they have different sizes and types, what should be considered first ...]]> VDX Paste Extrusion Working Group Fri, 07 Dec 2012 06:11:12 -0500 https://reprap.org/forum/read.php?180,18770,170137#msg-170137 Re: Simple Dispenser https://reprap.org/forum/read.php?180,18770,170137#msg-170137
So another try to write something into the forum ;)
Iam from Austria and you?
Mmmh no I dont have a linear drive, but most of the other stuff. Well I will try but if it lack could you do me one of these. I wonder if its possible to print some of the parts...

Your dispenser stuff looks quite nice. Do you think you could build me one of these? Iam not very familiar with mechanics and build technical stuff...so it would be a real challenge for me to do it on my one...What I would need is a dispenser for normal viscosity (water) which could dispense drops with volume between 15-50µl...

The pneumatic dispensers (two with the small black boxes and the bigger one with fixature for the CNC-Z-axis) were used for dispensing solder-paste or glue ... they can be used for fabbing too, but the big one is tricky to handle because of the big volume - i have to apply a vacuum-shot when stopping ...]]> VDX Paste Extrusion Working Group Tue, 23 Feb 2010 15:44:26 -0500 https://reprap.org/forum/read.php?180,18770,22377#msg-22377 Re: Simple Dispenser https://reprap.org/forum/read.php?180,18770,22377#msg-22377 if you take a close look, the one I found in the blogs and the one viktor made is technically the same, Viktor just has the necessary plate to mount the motor and syringe to. That's mainly all the difference.

And if I got nophead right th one who actually posted the picture I quoted above hasn't been here for a while, so I guess there is no other actually working on a syringe based extruder other than viktor.

But you can take a look at the fab@home extruder, they use syringes.

Genau! Think I can forget the idea of mounting that on a BfB Reprap... I'm not a mechanical guy but wouldnt a linear stepper require less space albeit being more expensive. Maybe the pressure generated would be less than this setup? Sad because I love this simple design.

I'll look into the original one that Sid posted. Is there an crew working on a 'standardised' syringe design? Syringe is referenced all over the wiki but it seems abandoned in favor of the thermoplast extruder way back.]]> unfold Paste Extrusion Working Group Thu, 26 Feb 2009 17:58:23 -0500 https://reprap.org/forum/read.php?180,18770,21736#msg-21736 Re: Simple Dispenser https://reprap.org/forum/read.php?180,18770,21736#msg-21736 [attachment 1428 Disp-montiert1.jpg]]]> VDX Paste Extrusion Working Group Wed, 25 Feb 2009 13:28:46 -0500 https://reprap.org/forum/read.php?180,18770,21718#msg-21718 Re: Simple Dispenser https://reprap.org/forum/read.php?180,18770,21718#msg-21718
for ceramic slurry i used another setup with thicker needles (coded green) - but they clogged occasionally after some minutes, so i mixed my own slurries with glass- or ceramic-dust and glycerin or waterglass as paste-basis.

Recently i've got some samples of hollow borosilicate glass-spheres in dispersion smaller 0,1mm size (peak at 0,05mm, range from 0,0001 to 0,1mm) what's an interesting fabbing material because of the better fluidity of the spheres in respect to the sharp-edged microparticles of ceramic dust.

The actual dispenser is fixed beside my mill-head on the CNC-mill - i posted some images in the german forum, but the posts are truncated and the (embedded) images are gone too.

I'll atach the photos when home again ...

here the images of the completed assembly:
[attachment 1426 Disp-komplett.jpg]


... and the cartouche-head:
[attachment 1427 Disp-UV.jpg]


In my first post you can see all the parts - i added only an L-shape-rail against freerun of the nut and a spring as cartouche-holder.

For UV-curable resins (especially "Acrifix 192") i added 6 UV-LED's.

There is no list - i milled some blades with the right holes for the special cartouche and have to make another set for the bigger ones ...

maybe you can modify the existing reprapped version (if you can get hold of the stls that is)
