It isn't really that easy, since the Form3 is an laser-based printer (not UV LED+LCD), the resin is much less sensitive and requires higher activation energy than the mSLA resin for the elegoo. If it does work, it will be very very slow.

Pro tip about holding water: process FDM-printed parts with a dissolver (f.e. ABS with acetone) and they become completely water / air tight. I've made many hi-pressure manifolds and valves that way.

@gnomish844 2 жыл бұрын

Also, play with layer height. Most people think smaller layers = better, but tests show that's not the case (check out CNC Kitchen, for example). Smaller layers may result in higher resolution prints, but layer adhesion is worse, which is where you get water leaking. Been printing water-tight parts on an Ender 3 for ages without any post processing.

Looks like your printers and cardridges are unreliable at best and dont work at all at worst.. Unfortunately i'll have to remove your Printer from the collection i am eyeballing at the moment.. Elegoo it is then. A Buddy has no issues with Elegoo, even if requiring more manual work e.g. when refilling.. totally worth less money spent and less frustration. And with the cardridge-style we have the same issues as with normal printers too.. the printer says its empty when its not, the company can make the material extremly expensive to buy and even refuse to print with other types of resin not from that company.. Really bad practises.. pure evil! Seems like you went the same route. Full on capitalism!

I'd love to see you experiment with more, cheap resins in the Elegoo. Things like Siraya Tech's stronger resins are very popular to mix into various ABS-like resins to increase durability and strength. I think it'd also be interesting to to experiment with different printing orientations. Printing the pieces on their side (as opposed to vertically) could increase their strength further. Layer de-lamination is less of an issue with resin versus FDM but it's still inherently present in the manufacturing method. Great video as always!

@severpop8699 2 жыл бұрын

Fun fact, I obtain similar results on a 200 USD second hand Core XY printer that I modified to suit my needs, prinitng in Polycarbonate, PLA, and other materials like PPS PEI etc. The trick to not spend 5 gran for a printer and 200 bucks per liter of resin is the after print rebake in popcorn salt remelting at some 10 Celsius under the printing temperature, and keeping it so for a few hours than let it cool over the night, that eliminates in the semiliquid state (guiyii state?) all micro bubles of gas (mainly air) from the FDM printed parts allowing the polymers to weld into eacother without the part changing shape, well something changes but insuficcient to make the part usless from a parametric point of view. In the end I obtain same quality (nearly) as injection moulded parts, without the perfect aspect because... 3D printed.

A couple tips on getting the raft off the build plate: Use a thicker raft (2.5-3mm), soak the build plate in the alcohol for longer (once the parts are removed) or in a worst case situation, throw the build plate in the cure tank for 10-15 minutes on medium heat.

I saw a review of this printer and the reviewer had the exact same problem and Formlabs advised to manually fill and then cut a slit in the bottle, If I had bought that it would be going back to source I have a Voxelab Proxima Mono 4K for the very little resin printing I do and its a great printer, the quality is top notch and I cant see the layer lines without a microscope and the build plate is quite big at 8.9", I printed a lid on one of my FDM printers that turns the vat into a bottle to pour the left over resin back into the bottle, no mess whatsoever, the lid was water tight after printing but just to be safe I gave it a thin coat of the resin and cured it with a UV torch I have a tray that fits the whole of my workbench so if I did spill any resin it would not go far and is easily wiped up, the next project is a fume cupboard, I have low odor resin but I also bought some ABS like stronger resin and that is quite whiffy and the printer has to go in the garage when I use that

@austinmurray2407 2 жыл бұрын

Material Scientist here, Tensile test pieces are indeed usually round and also have a narrowed part in the middle to ensure where the part breaks. for what you are trying for please increase the grabbing ends to be thicker ensuring you break in the middle or go for a wishbone that is much thinner but the same design as what you have. The main thing is you want to control the break. This is why most pieces are threaded to make sure you are not creating stressors but creating a good grip. For flat objects, you have to make sure your clamps can hold more than what you are testing but still be flat and I would have something between the flat metal and the plastic piece with a higher coefficient of friction.

It's too bad we haven't figured out a way to do resin printing with long fiber reinforcement yet. Imagine how strong we could make parts then! I'm also really impressed with the strength of that resin. I had always heard that you use FDM for parts that need to be strong and durable, and resin for parts that sit on a shelf and look pretty. Even if FDM IS stronger and more durable, this certainly shows that resin parts aren't just fragile things that will be destroyed the moment you look at them crosseyed.

This resin looks strong ! But when you compared it against your FDM printer you should have used more materials than just ABS, since ABS is far from being the strongest, even the common PLA is near to twice as strong in this specific test. And by the way the youtube channel CNCkitchen has an interesting setup to test the strength of 3D prints ! For example in the tensile test he made samples with rounded edges and rounded supports on his machine to reduce the stress due to a potential misalignment

Simply holding my fingers on the sample for a few seconds was enough to ensure that the wire would break where touched. (Obviously, these tests didn't go in the records).

You should have done wired Ethernet - always more reliable than WiFi. Also, you probably got a bite valve without the normal sized opening. Close the top vent and flip it over, and work the bite valve until the slit is all the way across it. You might need to start it a bit in the center with a sharp knife. This happens regularly with new material tanks, and is also discussed on the Formlabs forums.
