Long time no updates.  Guilty, but, BUT Here is a WIP Flash curing hardening of the resin printed objects:

Castin’ Craft dye from Environmental Technologies Inc – eti-usa.com

The only difference is the color – Opaque Yellow.
I have tried the transparent amber, yellow, blue, green.
Also I have tested Opaque red and yellow. The latter proved a good absorber or
the UV/NUV/Blue spectra per volume. It was able to limit the polymerization to a
very predictable depth no matter the exposure time. As per the instructions: use
1oz per 32oz or roughly 29gr per liter and at $6 an oz, it is perfect.I have
tested it with about 80ml of resin and 2-3ml dye and is fantastic, you have seen
the results.

Here are some photos and I have added them in the “Gallery” Section above.

Measurements are:

10mm X 60mm X 70mm

10mm X 70mm X 90mm

and I added 8mm holes with 15mm countersinks for M8 X30 bolt head that are 6mm deep  with a spacing measured off the Bracket ( Click Here ) in My case 26mm.

I have cut 3 sets should I need to make one fast

I had tested  JB Weld-Regular with some of the cutout pieces of Plexi. Seems to hold up the Plexi to Plexi. What I was concerned about was the Plexi to Glass.

You can use some 200 sandpaper to rough the glass and plexi mating surfaces and clean them with Aethanol or Isopropyl Alcohol 96% and some no-lint cloth.

After inserting the bolts and spreading a generous amount of JBWeld ( you can clean it up the oozing after it sets for a few hours ).

Follow the instructions for using JB Weld – I placed it in a warm room @25C. Keep the base on a level surface – glass down, as the JB has not set yet. You can use regular tape to keep the two from sliding.

Result is this:

I have tested it with the same resin ( say ~1300 cP@25 )and it seems to hold up very well for now.

This is Life – I hope to not have to  redo it AGAIN?!

Salutations!

Hope you like it.

This is the first completely printed object at @43 microns in X and Y. The Z resolution is @25 microns.

The first layer of the base is 200 microns and 9 more layers @ 100 microns @ 8 seconds exposure to over cure the resin so it sticks to the glass better.

The time it took to print it is 2h 45m. It has about 1250 layers including the base, so speed is about 15mm per hour @25 microns.

There is a slight elongation defect since NO vertical compensation was applied and I need more supports. The moment that the inner supports started printing
there is a stair step like defect.

It is smooth to the touch and as strong as the plastic from the videos.

It has not been post-cured. I took it off the printer and dropped it in Ethanol 95% – “Spiritus Aethylicus” – and stirred it around. After 10 min it was squeaky clean AND Disinfected LOL.

Went to bed last night @02:00 leaving this:

Only to wake up @6:30 with a result like so:

There are absolutely no problems with the New Build Base ( there will be a post about it ). It held strong and did not see any flex.

Once I scraped the excess resin off and wiped most residue off it looks like this:

In the aethanol 95% it goes for 10 min whirl around. I used a small glass jar I had around.

Here are the macro photos:
