Fast UV post curing unit.

Post#1 » Tue Jun 07, 2016 3:28 pm

My new curing unit arrived today, very nice!

So the method using the glass jar is intended to fill it with water. Should it be distilled or is tap water fine?

Is it necessary to use underwater or open air curing is fine too.

I have been curing in a microwave with the models submerged in water and then after drying the models I would cure in a nail curing box.

Is there a study that under water UV curing is enough. on its own.

I did experiment with UV under water in the past and my model would get some surface distortions. Softened surfaces mostly. So I stopped.

Just looking for some clarity on how best to use this sweet little box.

Thank you,

Curing underwater works because oxygen inhibits curing.

You can use tap or distilled. The box works great, just use it with water. I would avoid alcohol all together. Clean print with DAwn and water mixture. Ultrasonic for 3 to 5 min., rinse, then cure underwater. I cure most med and small rings for only 2 to 3 min. Have only cured really heavy pieces for up to 6 min.

I hope users dont' start overthinking the light box. Just use as recommened and u will never look back.

Thank you Robert,

I have been using dawn, however i do like to give the model a quick spay on alcohol to thin the resin before going into the water and dawn.

If u use alcohol with the soap and water and even the ultrasonic, u may get white chalk like surface residue after curing in the light box. It doesn't have any effect on the castings, but looks a little funky.

Just a heads up. I always used alcohol before the light box. U really don't need it because it never gets into the nooks and cranies anyway. I wouldnt' waste the money or the time. I changed after nearly 3 yrs of doing it "my way".

I am totally open to trying new ways and changing my old ways.If not, I would not be doing CAD or 3d printing.
The old ways of curing models have been working, this new box is a time saver.

With that said, Do you still use an oven or microwave curing before uv curing in the new box.
Or big question, is curing only in the new uv box would be enough.

The only thing I use the toaster oven for anymore is pizza and curing vat PDMS.

I have been amazed by what this new little Model Curer can do. All that I do is rinse model in water, hit it with air compressor and cure for 2 mins for average rings and 4 -5 mins for heavy mens rings.
Have fun using it and start enjoying the time that you now can save.

Got mine in a few days ago. Works great, I used to use an envisiontec 'flasher' p.o.s. machine to cure my prints. This is much faster and thorough.

I just got my B9 Curing box today from Robert and the first thing I did was unpack it, Plug it in... add water to the bowl and drop a fresh print right of the printer into the bowl ( after cleaning in dish washing soap). 2 minutes later, it was cured Better then anything .
Thanks for talking me into it Robert Howle,
These are really good and I highly recommend getting one of these from Robert as he is one of the B9 distributors .

And B9 team.... you have built a fantastic curing system.

Thanks,

I just got my unit today.. Think this will be one of the best purchases in a while aside from the printer itself. I was wasting 6 to 7 hours curing on my nail curing uv lamp and had to constantly flip/rotate the model every hour or so in order to get all areas cured. Now I can finally have my models printed in 2-3 hrs and drop these off to the caster the same day. ^^

To those curing with their units for 2-3minutes, do you have to flip your printed models or rotate it? I'm guessing 1 minute each side? Or is the lamp strong enough to cure all around without flipping the part? Also, will the model crack if you cure too long?

I leave the 'base' on my prints so I can stand them up and no turning or flipping needed. If I have a heavy print that must me layed down I cure for 1-3 min on each side. Really thick ones I cure for 6 min on each side.

thanks.. Was wondering if your cured prints feel brittle/hard plastic like or are they still kinda soft and hard rubber like?

I think my cured prints from my nail lamp end up really brittle/plastic like.. Didn't notice that after curing with this lamp. I only realized that just now. I will get back the casting on Friday. Looking forward to the results. ^^ Hope they turn out real nice.. The nail uv lamp has been giving me problems lately as I think the blubs are dying out.

Just got back my platinum and 14k gold casts back from my caster.. My casts have never looked this smooth/clean. :) This UV curing unit will be one of my best investments.. Highly recommend it to those who still haven't picked one up yet. I had cured my rings for 1.5mins on two sides. No more waiting 6+ hours, flipping the prints every hour or so, and still having them turn out with slightly rough after casting.
