QuoteMileHigh3dII I've been doing something similar. I use acteone and some ethyl acetate as the solvent. I do about 100g of ABS and 150 grams of Acteone and stir it up with a wooden popsicle stick. I stir it up a few times over 12 hours. When it seems like I have it pretty well dissolved (really check the bottom) i add the ethyl acetate. It is in hardware stores as "M.E.K Substitute".

QuoteDirty Steve Hours for cold polish? It takes 40 minutes, if you leave it without checking on the progress, dries overnight. Unused metal paint can, completely lined with doubled up paper towels, held in place with magnets, soaked with acetone right to the limit the paper towels can hold. ABS part set on a sheet of glass, and the metal paint can inverted and placed over the part. DO NOT checkby Wolfie - General
Correct. You do not HAVE to heat the acetone. You can contain it and let it work on the part for hours. And hours. By heating it you shorten the process substantially. And yes I did it a couple times with the towels and a glass jar. Took like 5 hours. The print took less time than the smoothing. The same process is done in 10 minutes or less (including the heat up time) by using the priby Wolfie - General
Quotethe_digital_dentist Acetone boils at about 56C. That Peltier junction device is like any other semiconductor - you'll have to be very careful to ensure you can dissipate the heat it produces or you'll kill it very quickly. Your idea seems overly complicated to me. Acetone isn't expensive or toxic enough to bother with vapor recovery. I think a real problem to be solved is circulating tby Wolfie - General
Ok, I have seen many different videos on AVF and most have the same theme. Pour acetone in a glass jar, heat it to 120c stick part in for a few seconds and remove. There was one though that used an bucket of icewater, pump and a deep fryer. The general theory of that one differs in that it recovers at least some of the acetone vapor and is less wasteful in that aspect. It also reduces overfloby Wolfie - General
Well. I got a Taz 5 instead of a Taz 4 and I am pretty ecstatic with it. The borosilicate glass bed covered with PEI upper surface requires (at least thus far) NO prep to print on. In fact the instruction maual recommends AGAINST most of the bed preps especially ABS juice. So far I have printed with PLA, ABS, LayWood, Flex EcoPLA and 618 Nylon. In fact, the ABS adhears so well to the bed thaby Wolfie - General

QuoteQcks_ Modifying the 5 gallon bucket is easy: You need a drill, a hot glue gun, a hole saw attachment for the drill (around 3/4 inch... maybe a little bigger), a regular flat head screw driver, a pair of scissors, and a vaccum seal bag from walmart (or other big box store). Cut the bag down so that you are only dealing with the vaccum seal. Pry apart the vaccum seal. cut hole in lid, snapby Wolfie - General
Quotevreihen I've seen a few entries on Thingiverse where people have installed small (25W) light bulbs into the aforementioned 5 gallon buckets in lieu of desiccant. Don't know if I would leave it unattended. I like Werner Berry's idea from YouTube. He uses a large Harbor Freight paint spraying vessel as a vacuum chamber to dry/store filament. Personally, I'm thinking that 3DXtech's Zip-Locby Wolfie - General
The buckets are a nice idea. I was planning on putting rechargable desicant packs in. I use these in my gun safe as well as my bulk ammo cans: When they turn pink, you just plug them into any 110v outlet (built in dryer heater). I use a simple dollar store 3 way extention cord and I can charge 2 at once on it.by Wolfie - General
So, being new to this ballgame, I read somewhere that some of the plastics are hygroscopic. Anyone have a good list of which ones do and don't? And what do yall use to store the filament in?by Wolfie - General
Well, I found out that Cura (from LulzBot's site) opens and imports OBJ. So all I need now is a STL>OBJ converter. In MODO, yes you can flip polys. There is an option to view the normals so you can tell which way they face. Don't think there is a tool that checks if the shape is manifold. Are there tools out that can do that?

I have a 50w CO2 laser so mine is quite a bit more powerful than yours which appears to be a diode based laser. I cut plywood, paper, fiber board, mdf as well as various plastics. I also engrave anodized metals and also use Cermark products to mark steel and other metals. My laser is in a steel cabinet due to the deadly high voltage involved in a CO2 laser tube.

Yes, I saw you made one. I also saw you were having some troubles with some smell left. If there is smell, there may well be hazardous fumes.
