Post Curing and Close-Up Pictures…

January 8th, 2012 2 comments

Here is the UV Lamp I used for the post cure process and some closeup pictures of the first object printed in layers:

I bought the UV Money Detector for a few euros with a bad power cable and replaced it for small change.

The following picture is ( from left to right ) the Silicone VAT sample, The Teflon Sample and the Teflon Sample Build Base with long burn in Cycle:

You may recognize the first one as it broke in the Video :

The next one is pretty  smooth with the exception of small bubbles. Guess the resin should be left alone for an hour after the stirring and shaking:

Here is a closeup through a X45 mini microscope I had bought for 3-4 dollars from ebay:

The slices are 10 x 0.1mm and the first one is 0.2mm.

And you can see the layer slices in the second one:

 

Close up of the Bubbles on the surface. Next time I will brush some resin on the glass before dipping it in the VAT with resin.

 

Hope you had wonderful holidays!

Cough – Cough – I know the people from the south hemisphere did!

 

The Good, The Bad and The Ugly…

Ok, here goes:
The good… It works fantastic! You have seen the proof in the videos.
The Bad… The teflon lifts up and upon landing it is wrinkled. Needs to be restrained to the bottom ot the VAT.
The Ugly…The force is not to be reckoned with. The HDPA build base and the
silicone did not make a strong connection and with the viscosity of the 50ml of
ED3 and 50ml of ED4 ( 1600@25C and 1080@25C respectively ) it came undone:



Again don’t mess with “the force”: It cracked the corner of the 5mm glass
silicone VAT I made when experimenting with it.

Lessons learned and will be corrected in the next VATs and Build bases.
