How long does it take for a full model cure?

[mikej]

"Recommended cure time: Small models 2-3 minutes. Large models 5-10 depending upon thickness and size."

any risk to damaging the model if it is in longer?

[mikej]

Never tried more than 10 minutes (no reason to). I doubt you could hurt the model unless you've used alcohol to rinse, then it may crack (regardless of cure method).

[Robert Howle]

After diff testing i settled on no alcohol. Just swish well in thick solution of Dawn and water then ultrasonic for 3 to 5 min. Great results at 2 min on most rings and 6 min on heavy items. This will hold multiple pieces. It's really nice to print wash, cure and start building trees for casting. This is saving me 1 to 2 hrs per printing and curing session. You will love this machine.

I printed a nearly 2 inch long, really thick, Megladon tooth (shark) and cured for 6 min. Cast perfectly. I print only with Emerald green presently.

How long does the bulb last?

[Robert Howle]

Could be wrong but I think the uv leds are the 100,000 hr rated ones (the unit contains and array of leds). Mike can chime in hear. Others have been beta testing for months with no issues as to bulb life.

No lamp, multiple LED's. LED's don't "burn out" but can dim with age. Typical values are 70% after 50,000 hours. (50,000 hours is over 136 years at 1 hour per day!)

[Robert Howle]

Thanks Mike, that's always the second question after, "How much is it ?".

[noahbern]

Will this be at the JCK show?

Yes, it will be on display there.

Includes glass vessel to cure models under water.

Ive been heat curing my models, how does this work and when is the applicable.

[Robert Howle]

I was doing only heat curing. Monitoring the oven an all the other stuff, including microwaving, etc. was taking me about 2 hrs per batch of prints. Now I only spend about 10 min which includes removal from the build table, Dawn wash, ultrasonic, and curing. Saving me over 1 and 1/2 hrs per print batch. and I dont' have to wonder "is it really cured?".

What is the advantage of curing the models underwater.

[mikej]

Surface cure is inhibited by atmospheric oxygen. Putting it underwater limits surface contact with O2 and allows the surface to cure more completely for a given amount of exposure.

[lobby]

I uv cure underwater in a nail box for a few hours, then microwave in water for two, 5 minute intervals.

With this machine, I won't need to microwave anymore?

[Robert Howle]

No more microwave needed. U should read the entire thread. Most everything is just wash in soap and water, ultrasonic for 3 to 5 min, cure 2 min, and build trees for investing.

This is a huge time saver for me.
