3D Printer DLP Printing with UV resin…

What can I say? The title pretty much gave it away…

It’s an early Christmas Present…

Questions will be partially answered after 27th and fully after New Years!

Red Red Wine Plexiglass 2423

December 14th, 2011 5 comments

I have tested a Mini VAT resin with a 3mm thick sample ( 2423 ) red transparent
acrylic plexiglass piece provided by a local company and the results are only
mediocre.

It seems to block some, but not all of the UV and Near Visible.
Comparing to a Lee Filter sampler “Bloody Red”, the 2423 allowed a 0.5mm resin
slice to polymerize in 2~5 minute exposure, while when it was placed over the Lee Filter it did not
exhibit any polymerization for 20 min.

 

This is what it looked like in the mini VAT. A tribute to the RepRap crowd for inspiration and information.

I would assume (have to confirm) it will be safe if used with an incandescent or florescent bulb. Do not expect the red 2423 to stop the UV from sunlight or other sources from ruining a VAT full of resin and the print.

Some pictures of where it stands.

Decided to step back and take some shots of the overall state the machine is in. Hope you like them ( what’s not to like?):

And some closeups of the Build Base:

I am happy to report that the remote of the DELL 5100MP is actually a wireless one, not an Infrared – Meaning the projector can be powered up without having to leave a hole for powering up in the side panels. Also the 5100MP has a web interface – meaning I can switch it on via software. And yet another option it has that may prove useful is the ability to play PowerPoint presentations over a network – If it can also be controller with software I might not even have to install PowerPoint Viewer 97 on the PC. We shall see later.

Prost!
