New video of the 4 rings platform:

First Fully Printed Object

January 18th, 2012 7 comments

I know I made an announcement and here is the start:

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:

A close up of the slices:
