[@nathanblanchard8897]

It’s so tough for individuals making huge projects like this. Micronics likely needed more time and money to finish their idea, but shouldering that without outside investment isn’t a small feat! The kickstarter could have helped with that, but the promise of delivering a product in a timely manner was where things went wrong imo. What would have been better is a campaign that promised a discounted rate on a later produced machine after 4x the time they assumed they would need. Idk if kickstarter would even allow a campaign like this though, and the excitement of sharing the awesome product you’re making while creating a company to sustain it is understandable. To be clear, I think the Micronics guys are super talented, and ended up in a situation where they needed more time and money to finish their idea, but didn’t have that option. Hindsight is 4 years ago or whatever and it is easy to make armchair quarter collector calls after the fact, but I blame their “failure” on the situation they ended up in and not character flaws inherent in them as individuals. Hopefully FormLabs doesn’t just nuke them and we see some improvements in their products (ie price lol) from the acquisition. Also I’m not implying you feel they’re bad people, but just clarifying my thoughts! So, give this guy money I guess? Or advocate for community backed companies to support him? Either way, I’m looking forward to seeing what comes next!

[@edingerale]

holy shit, that's one heck of a cool project you have there, mad respect maybe some tips or rather suggestions from someone who works with a SLM machine (from Aconity for anyone interested), if I mention anything you already addressed then it's just me being too enthusiastic and writing this comment while watching the video: - as someone pointed out, when working with 316L a lot of people use base plate heating, 316L normally takes around 300°C, for cubes it's relatively safe to not heat cause you don't have that much volume in comparison to the area connected to the plate, but anything with a different area to volume can make some problems cause the stresses get too high to handle for what little support you have, if you ever go into aluminium like alsi10mg use 200°C, that can also reduce your adhesion problems - 316L is notorious for spatter, if you have problems with that either reduce the layer thickness (we would use 30 um with such problems) or take a look at the gas flow, we had a problem with it being too turbulent and thus leading to a different print quality depending on the position on the platform, a slight modification to the exit nuzzle made it way better and more consistent over the whole platform, also drying the powder can help - concerning your density, it would be pretty cool to see a cross-section of your parts, depending on the form of your pores you can see where you are concerning energy, big irregular pores? probably lack of fusion, so more energy. big round pores? probably keyhole pores, so too much energy. lots of small round pores? gaspores, can't do a lot about those except for drying the powder and going slower with lower energy, or remelting every layer so the gases can escape the meltpool - we have 2 solutions for the coater, either a silicon lip or a carbon brush (there exists a 3. one from the manufacturer, a metal lip, but that's just shit), the silicon lip gives a way smoother powder bed but can break off any high spots or parts that threaten to rise up due to a lack of fusion or warping and it doesn't work with higher temperatures, becoming too soft and ripping out of it's holder, the carbon brush is way more forgiving but can lead to valleys in the powder bed, where particles are stuck to the brush - normally we burn in the first layer up to 3 times, just because you can't really control how thick it is, so rather put in more power and be sure, than having too little, putting in too much power will even out with the next few layers anyways - printing bigger or just a lot of parts and thus crowding the platform can lead to not enough powder being transported, so we normally brush over with a supply factor, meaning 2 - 3 times the height in powder that we theoretically need being brushed on, saved my ass more often than I want to admit hope my rambling could help you even a little bit, good luck with the project, would be so cool to see bigger and more complex parts being printed

[@metalmatters]

Thanks for sharing all of that info. I don't know if I will be able work in any preheating in the near future but will keep it on the cards. I found a recommended temperature of 50 - 80C for SS316 in a MDS and was referencing that. I think at the current scale things should be alright.

[@TheAngryZaidy]

Please protect this man at all costs. Genius! Hope you had time for a job while working on this project.

[@facenameple4604]

Try using two or three powders together, of different particle-sizes. I forget the math on how it works, but smaller particles will fill void-space of larger particles, and you should be able to get the powder itself up to like 85%-90% of pure/solid material, and thus that should help with the fusing of the particles to make a solid piece.

[@bencolbourn5691]

how do they all stay evenly distributed?

[@RishabhX3576]

I guess you're talking about Fuller Curve Approximation

[@Jonathan-ex3sl]

that can make spreading the powder quite difficult due to agglomeration. industry standard is to use 15-45 or 15-50 um powder distribution. it provides a good balance between density and flowability of the powder

[@StepSherpa]

Smaller particles also melts easier meaning that you now have something very hot that will spread the heat to the larger particles, this is very noticable when casting as as soon as you just have a little molten metal in the bottom its very easy to melt more metal rather than a hot empty crucible

Hey, a lot of professional systems use carbide blades for layer deposition and scraping. You might want to look into replacement carbide blades for paint scrapers. They're flat and sharp and fairly inexpensive! This has a second effect of being able to knock off high spots, but also can jam and remove parts if the build Also, stiffness of the recoater and powder beds is super important. Some linear slides may help tremendously

[@excitedbox5705]

Glad to see you finally use the tips I gave you on your first videos over 2 years ago and having some success. Some more things to try, is switching the process gas. Nitrogen is easy to produce using molecular beads and an aquarium pump + 2 valves. Total cost around $50. The atmosphere helps control spatter, off gassing and oxidation so it is quite important for quality. Second, is the powder leveling scraper in professional machines is usually a ROTATING cylinder to help compact the powder and increase density. Another option low cost machines used was coated metal powder that would get "sticky" from the heat, which reduced spattering and helped control the weld pool. Many of your problems seem to persist due to your substrate bed, so that should be your first focus. It is really not too difficult to cut 4 groves in a section of pipe and use metal ball bearings constrained in the head of a torx or hex head screw as guide rollers. This will give you precise Z axis guides and either a cable/wire + pulley or screw mechanism for sub micron height adjustment. Super LOW cost sub-nm Z axis: An Upside down T with a wire attached on either "arm", fed over 2 V groove bearings mounted in slots cut near the top sides of your guide-pipe can be wrapped around a capstan, beneath the guide-pipe so the T's foot raises as the capstan turns. Think wire powered hydraulic piston. As long as the wire is thick enough not to stretch you can get sub nanometer precision. 1 full rotation of the motor lifts the platform 1x the circumference of your capstan. Add a pulley between stepper and capstan to subdivide. I have built
