Best XY Focus Method Tip

Just sharing what I have been doing to focus XY DLP printers perfectly lately. You need a glass microscope slide. http://www.ebay.co.uk/itm/100pcs-Pre-Cleaned-22-22mm-Microscope-Accessories-Glass-Cover-Slides-Coverslips-/322029569144?hash=item4afa754478 Cheap USB microscope - i picked this one up fr...

Re: OLO3D printer lets you print with your smartphone

Looks like something new! Im not sure how they are releasing each layer? Looks like the same sort of separation as on the Titan1 .. which i thought they patented? Downsides seems that print times are high using the limited power from the screen and "daylight resins" are very brittle. Altho...

Re: Carbon3D

Saw this also, will wait to see the final stats and info. I imagine finer parts could be printed with no release cycle, as the release cycle forces was what is preventing reliably doing 15um layers on the B9 But its DLP printing without a release cycle, dunno why they have made their own special nam...

Re: Vat Nano-Coating?

Will do a test with the resin curing on it. But this brand i have does make the surface go cloudy! So will have to test with a clear version later on to be suitable in a vat.
May well be as you predict Tim ;)

Re: first print - fail (as expected), layers did not stick to build

quick edit: has anyone tried using release agent on pdms? While I don't actually think it would be a good idea, who knows.... ? Idea popped up mostly as I have several sprays at hand (both silicone oil based and oil free). Yea, dont do that :P the PDMS needs exposure to oxygen to inhibit the resin ...

Vat Nano-Coating?

I picked up some nano-coating hydrophobic compound and was going to test it on a vat as a pdms alternative. The nano particles mean that with any liquid in contact with the coating - only around 3% of the surface is actually in contact with the material surface and is instead floating on a raft of a...

Been using a high pressure water flosser to blast uncured resin off prints

Light Normalization

Lets go back in time to victorian photography. :D use silver nitrate paper which changes colour exposed to light. Then use this an an alpha mask to adjust the projector brightness accordingly. https://www.youtube.com/watch?v=GNp-V3viRS8 I mentioned this before a while back, i owned a Miicraft printe...

You are still printing prongs 200-500 micron wide? Looks at this ;)

If thats the same tech i was looking at, covered this briefly for a university research project, was using single photons to cure the material, which have a much shorter wavelength than visible light, IIRC

Wonder what print time it has though! ;)

NuVat by Evert

Sounds great :D When do we sign up? ;)
If more tests are needed - happy to help as a Spot HT resin user - its very reactive and harsh to the PDMS. Would be great to test with the new coating.
Good luck with the final trials.

Post Process Methods?

I was thinking what was the best post process for getting prints fresh off the machine to nicely cleaned up and cured? What im doing at the moment is: Print sprayed with 99.9% iso alc to remove the worst of residual resin. Throw it in the ultrasonic cleaner for 6 mins, using plain old tap water ...

How improve the build table model adhesion

I think if you make the print adhere to the table better - this is going to be a moot point. Since by the sounds of it, the new VAT coating will still cause each layer to stick while printing, meaning that the part printing may warp or bend or be more likely to fail or have the supports snap away.

b9 chassis without projector

Its easy to add and remove the projector when needed, so that would work fine. If mike will sell a kit without projector, is a question for him.
Good choice of printer Richard ;)

B9 Printing Progress Log

Yea, was using 2 attach layers and 0.5mm (or something) for the foundation thickness.

Now am using 3 attach layers and 0.075mm foundation thickness. :D So there are no foundation layers which are not highly exposed as attachment layers. Will do another print with more detailed stuff tomorrow

B9 Printing Progress Log

Ok spot on, near flawless results now :D Really pleased, so reduced attachment layers to 3 and support base thickness to 0.075mm (3 layers) this avoids the "slate effect" where the layers shear off. Cure times at 0.55s and 0.4s now All supports printed fine, one or two harsh lines but i think that i...
