I always wear a respirator when sanding resin models (both cast and 3D printed resin) as you definitely don't want that poo poo in your lungs. Wet sanding helps keep the dust down.

Kabuki Shipoopi posted:Just picked up an Anycubic Photon Mono 4k at microcenter for $149.99! I was gonna buy resin as well, but all they had was Inland branded resin, and considering I don't know anything about resin printing, I thought I'd wait to do some research. Welcome! I've had a Photon Mono X for almost 2 years and had a Photon for a few years before that. Youtube is probably the best place to learn about new or different resins by simply searching for the brand and type you're interested in. Goon favorite brands include Elegoo, SirayaTech and (lately) Sunlu. Most 3D printing channels will have a variety of content and here are some channels I've found helpful for varying reasons: Uncle Jessy Vogman TableFlip Foundry I began with Chitibox and moved entirely over to Lychee Slicer as I appreciate their continuing support and additions to the program. I subscribed for their Pro version and I'm not regretting it, especially with the latest update that includes planar cutting and inline support painting tools. Lychee Pro will also check for 'suction cups', those pockets you mentioned. Most settings are contained in the print file, the only setting I can recall needing to change on the printer itself is the UV light power (basically everyone recommends knocking it down to 80%) and that setting has never defaulted upon powering down. Any worthwhile slicing software will support Anycubic printers so no worries there. It's much more important to calibrate your printer for the space it'll be working within. This means changing the properties and settings for your particular resin within your slicer and doing calibration prints. I recommend starting out by checking out settings for your resin here as a baseline starting position: Resin Settings Then slice and print some calibration tests: 3D Benchy Cones of Calibration Cubes of Calibration Finally please be careful with resin printing, the poo poo is toxic and messy and likes to get everywhere. Some good nitrile gloves, some silicone baking mats to catch spills and a lot of shop rags will go a long way to keeping things relatively clean and safe.

Bodanarko posted:Neptune 3 Plus back in stock on elegoo’s site for the US. I’ve been very impressed by what I’ve seen in reviews of the Pro/Plus/Max and have been wanting something with a larger build volume than my Prusa Mini+ and E3Pro. About time but I figured things would be back in stock today. I'm in the same boat, a Max would've been nice but a Plus will likely suit me just fine.

Learning all the settings inside of PrusaSlicer was really worth it. I'm getting some really nice prints out of my Neptune 3 Plus after tuning stuff in. I was hoping to take advantage of Lychee Slicer since I use it for my Photons but it's just not there yet for features.

HDF can also contain formaldehyde and sucks considerably more (in terms of manufacturing efficiency) than MDF when laser cutting.

Also we've been talking recently about laser cutting in the 3D Printing for the Tabletop thread which might suit this conversation better. In my experience, MDF is much better to laser cut for tabletop stuff than plywood simply because it tends to be way more flat and less warped. I've gotten some 1/8" Baltic birch that looked like a sail in the wind and that's a real pain in the rear end for focus distances.

The main worry once you have adequate and proper ventilation is getting crud on your mirrors and surfaces that parts move on or along.

Speaking of after purchase support, my Plus might've had a leak around the nozzle as my heat block was covered in melted PLA. It was almost all under the silicone boot so I don't know how that could've happened with a failed print but Elegoo is just sending me a new hot end. That's pretty cool! I decided to replace the heatbreak to go all metal when the new part comes in so it's nice they're not giving me the run around.

PBCrunch posted:I bought a used Ender 3 Pro. My first "useful" print was a bracket to hang up a Makita battery pack charger that doesn't have keyholes for wall mounting. To use the printed object, one removes the little rubber feet from four holes on the bottom of the charger and then puts these four little printed pegs into those holes. Clough42 talked about a few different things that can cause real world dimensions to differ from a digital model after it's printed. The vids are a few years old but I think the information is still valid. https://www.youtube.com/watch?v=0dFThbwAx2Y https://www.youtube.com/watch?v=zxA3hJBpKr8

Zorro KingOfEngland posted:Is there a laser cutter thread? For lack of a better term, is there a Prusa of laser cutters? I can't seem to find much between a $400 K40 and a $4000 Glowforge. Open-frame laser cutters scare me and I'd prefer to pay a bit more so I don't have to worry about my house burning down or my eyeballs falling out. There's no thread that I'm aware of. The big difference in price comes from the type of lasers being used, diode vs CO2, and there aren't many options in the sub $4K arena for CO2 lasers. Gweike Cloud machines are just under $3000 and I've heard good things about them. They apparently have a ~$2-2.5K machine coming out soon.

I'll attest to, at the minimum, Elegoo's customer support being top notch. My N3 Plus had a leaky nozzle and they sent me an entirely new hot end, at no charge at all, after I emailed them a pic of it. It's been chugging along 24/7 ever since and every print has been great after a little tuning and calibration. It's my first FDM machine and I'm really happy with it.

I decided to make my own monitor light bar rather than buy some cheap poo poo from Amazon or drop more cash than I was willing to spend. Thanks to the folks in this thread mentioning tips about PETG, my first print after a temp tower turned out really great! I'm now ripping off two 11" lengths to use as LED diffuers. This is Giantarm Clear PETG at 235/80 on an N3 Plus using the generic PETG profile in Cura.

smax posted:The old frame is metal. The frame in that picture is a plastic injection molded part, the circle with a 22 in the center is a dead giveaway, not to mention all of the visible injection points. The apparent rigidization is to bring its stiffness up to be comparable to the older metal frame, if I had to guess. From their press release: quote:The cut aluminum frame we used so far is now replaced by a brand new die-cast aluminum frame (the translation previously stated “injection-molded” which is not correct). To be more specific: we’re using an aluminum-based alloy that is first injected into a two-part mold. After that, the raw cast frame is cleaned from technological runners and other casting scraps, sandblasted and powder coated.

Big thanks to this thread for some of the knowledge imparted, I was having weird threads coming off my prints and finally fixed it by tuning my retraction settings. It wasn't stringing, it wasn't hairy little fibers, but maybe a dozen tubes that were 3-4mm long at a full 0.4 diameter or so coming out of the piece. Really strange but lowering retraction distance and slightly increasing the retraction speed eliminated them.

loving A. I was wondering why all my bridging and overhangs started looking like lovely, droopy messes. Maybe the setting that's capping my fan speed at 40% is the culprit, how did that happen.

I named my N3Plus Mr. Chungus, I can't imagine where I could even put a Max. I did recently complete making this upgrade for it: https://www.printables.com/model/457453-neptune-3-proplusmax-dual-5015-cooling-shroud The hot end fans are now capped at 50% speed, printing PLA at 75mm/s, and the PSU fan is now the loudest component. Pretty nice!

I had an issue with my N3 Plus that necessitated utilizing Elegoo's customer support and it was a very painless, quick resolution so +1 for that. I know there are some differences between the Plus and the Pro but the consensus so far (and my own experience) is that these printers largely Just Work. I'm very glad a Neptune was my choice for my first FDM printer.

Bondematt posted:I had TPU jam as a neat little knot once. I had to mostly disassemble my hot end to get this bugger out. The heatsink/brake/block/nozzle is all mostly one piece that comes out when you remove two bolts from the heat sink (after removing the breakout board and head shroud with its fans) and then I had to push the filament out. Just unsure how it was caused, this is normal PLA and I haven't encountered this issue before.
