Finally ready for Prime Time

Thanks, Fernando and Robert! Maybe you could tell your non-B9 friends and some of them will pledge. :) It would be great if you posted on social media. We're planning a blitz in the next day or so.

Finally ready for Prime Time

Hi again, everyone, I'm back after a number of months trying to deal with medical issues. I've been using the B9 to prototype what I hope to be a useful invention. Please check out SnapNSave-Bottle on kickstarter and, if you like it, support my campaign. https://www.kickstarter.com/projects/12029381...

Acetone Vapour

Yes. Well - sort of... I haven't used the vapor approach, but I have wiped my B9 resin prints with both Acetone and MEK. They clean the pieces nicely (better than alcohol) but they do not dissolve the cured resin.

Resin cured in area not exposed to projector

Hey Robert, For scraping I prefer wood. For small areas I take a wooden chopstick - one of the nicer, square ones - and, with a razor blade or box cutter, I form the chopstick into a blade on the end. Works great and doesn't scratch either acrylic or glass. For really big areas I use a 4x4 fence pos...

White space

Nice work! I see what you mean. I, however, need to let someone else comment who has more experience than I have with this type of print.

Whoever comments will probably want to know the resin brand and type and the printer settings.

Regards,
Peter

GEN 2 ALUMINUM "KAT VAT" coming soon!

Got mine today as well.

I think the addition of this vat makes this printer the best thing on the planet!

Kudos to both Mike and Kirk!! Two super heroes!

I hope it's not politically incorrect to wish all of you a Merry Christmas and Happy Holiday Season! Here, right on the Pacific Ocean, it's in the high 70's - not much of a White Christmas here... http://www.b9c.com/forum/files/uploads/2013/12/n5edx-rein1-sm.png http://www.b9c.com/forum/files/upload...

Prints fall off grow plate

Make 'em stick better :)

I suggest a more substantial base; from that pic the base looks a little thin and narrow. Try it with the heaviest supports and plenty of them. Also a longish first two layer cure makes for a strong stick to the table.

Vat cleaning after using MakerJuice SubG+

I used to be able to buy MEK (in quarts or gallons) at Ace Hardware, Lowes or Home Depot. Now, in California, the stores can't carry it. I have to order it to be shipped from Texas.

Vat cleaning after using MakerJuice SubG+

I use MEK (Methyl Ethyl Keytone) for cleaning all of the printer parts and prints. Use it in a well-ventilated area. It's stronger than alcohol but doesn't seem to affect un-annealed acrylic. MEK will strip paints and damage some plastics so test it first with a cotton swab. It will dry out your ski...

First print failed need advice

I've found that it's really important for the first couple layers to have a long exposure time. I use a resin that's tinted darker than Cherry so adjust yours accordingly. I use 40 seconds for my first two layers. The trade-off for going too long on exposure time seems to be damaging the PDMS so don...

Opinion?

It sounds to me like EDDMT has already done those steps and he's zero'd in on the B9C as a final contender. Just before I bought my first plane I was a little frustrated with my flight instructor. Every day I asked him what plane would be nice to buy. He responded each and every time by saying "They...

Spot-e(lastic) resin with B9C

Looks like it's worth trying. Too bad it costs so much to ship to the U.S.

Anyone know of North American distributor(s)?

Reapplied PDMS and it cured level

I bought all of the stuff to make a heating box but haven't put it together yet. I did my only PDMS coatings at room temp. One big advantage to slow curing is that all of the bubbles have time to magically disappear. Where I live the daytime room temps in my house range only between about 65 and 70....
