I would love a video just about your 3d printers and the quality expected from the parts produced

The 'quality' of a part will always a combination of how a part is designed, quality of raw materials used and the tooling used. Tooling can constrain some upper limits to quality but limits will vary across a design depending on how the design is composed. Quality is not a number but a set of desirable outcomes covering many aspects of part design: including, but not limited to functionality for a purpose, a parts physical appearance, durability, etc. Perhaps this is why "Design for Mass Production 3D Printing" is a series of videos, not a single video.

Also, you're in the right place at the right time for upcoming tech developments that mitigate current drawbacks of FDM.

Good points for choosing fdm, it's important to discuss its short comings as well because if tje shortcomings are not discussed with the customer thier expectations will nkt be met. I operate a resin 3d printer, I print figurines and models that require pixel perfect fidelity. Fdm simply can't do that. It's important as a business to have a small R and d internal think tank that can combine the best of both worlds. You can make an infill designed to interface with a smooth piece printed on a resin machine. I've built things where tje fdm might make the "frame " but the finished stamping parts are resin printed. Fdm will loose once plastics are phased out don't bank on the old supply chain for more than a few more years. Looks like you make your own filament, I'd source bio base for filament and move away from the plastic. I also love how resin printing prints a whole later at one time, true cleaning is a hassle when your unpracticed but really it just gives me more opportunity to scrutinize the piece for qc and give it a bath in the uv curing machine. I appreciate you videos, remember every process has its disadvantages.

Thank you so much for the Conversation we just had, I cannot tell you enough how much I appreciate it. You have truly given me a plethora of ideas regarding my super secret squirrel projects.

As Tom Peters said, "Stick to the knitting". So know what you're good at, and why you're good at it, and stick to that.

I love the simplicity of FDM and the quality and speed just keep improving, all these years later. However, MSLA resin printing was slower to wide spread use so now it's catching up and improving at an even faster rate than the more mature FDM technology. The 0resin print quality is far superior, now comparable to injection molding. The mechanical strength is far better in all directions as the parts have homogenous strength. Some of the "ABS-Like" resins are incredibly strong because it's polyurethane... like a hockey puck. The cost per kg of UV cured photopolymers is coming down and is now close to the cost for FDM, at least at the hobbyist/consumer level. The cost of the resin printing machines is at parity with FDM machines. Because they print an entire layer in a few seconds, the MSLA speed is faster than FDM. The only big problem remaining is post processing, usually requiring expensive, smelly and messy washes in isopropyl alcohol, drying and UV post curing. If that could be simplified and/or automated, FDM becomes a dead technology. There is nothing inherently difficult in that post processing improvement process. I'm surprised I haven't seen someone doing for MSLA what Slant 3D has done for FDM.

Resin printing often requires support where FDM doesn't And post processing of that support is harder. You often need to sand away thé divots these supports leave behind. Also, resin is a nightmare material. Hydrodynamics are hard to predict and it gets through tiny holes and makes everything sticky. Having everyone be careful in mass production Is a difficult requirement.

@@iluzonik- I design structural parts that do not require supports in most cases. I've found it no more difficult to avoid supports on resin 3D printers than FDM 3D printers. I think the reason there are more supports on resin 3D prints is because people use resin prints for complex art figurines, miniatures, game pieces, etc. Resin is a gooey mess. That's why the entire process needs to be automated so a bottle of resin is added to the machine like loading a cartridge (no bottles to open, no drips, etc.) and cleaning supplies are loaded in a similar manner and fully formed parts pop out the end. Toner is messy and electrostatics are hard to predict (humidity, etc.), but 2D laser printers can be operated and maintained in routine use by a receptionist.

@@iluzonik - I resin print without a raft. I avoid damage to the bottom of the part when removing it from the build plate in a few different ways. It starts by designing the part for resin printing. There needs to be enough surface area to ensure reliable part adhesion but not so much that part removal is a problem. Resin printing allows arbitrary orientation without concern for inter layer adhesion as is a major issue in FDM) so it's easier to tilt a part to choose the best surface to optimize print surface adhesion - not too little but not too much. I sometimes design the part with some macro surface texture or ribbing that looks decorative but it reduces surface adhesion. IT also helps to design the part to be easily separated from the bed. A fillet or chamfer on the edges of the surface in contact with the bed allows a plastic scraper to slide slightly under the edge of the part and lever it off the bed. I even array parts to allow best scraper access so the parts are individually levered off the bed with minimal banging into other parts which can result in surface scratches before the soft outer resin is post cured. The resin process needs to be optimized. Different resins and even different colors of the same resin can have very different print properties. The first layers need to be optimized so there is no elephant foot (overexposure) and the adhesion is adequate without being excessive. I have a dream of a cleaning station that allows me to place the build plate on top of station 1 where the parts hanging from the bottom of the build plate are sprayed with semi dirty alcohol to pre-clean most of the excess resin, then the cleaning station slides the build plate sideways to scrape the parts, one-at-a-time into an alcohol cleaning tank where they're agitated. The basket lifts up to drain the parts and they're dunked into the second tank with cleaner alcohol and agitated again. The parts are then dumped onto a conveyor where they're dried with forced air convection with a little tumbling to ensure they're dried thoroughly, then the parts are exposed to UV to post cure them, again with a little tumbling to ensure they're cured evenly, and finally the completed parts are gently dumped out the other end of the cleaning and curing station. The build plate is scraped, washed, rinsed and dried at the same time. The used alcohol is UV exposed and the precipitated resin is filtered, with new alcohol added at the end of the process and the recycled alcohol transferred back up stream until it's eventually disposed after spray cleaning the resin soaked parts fresh off the printer in step 1, minimizing alcohol consumption and waste.

I’d love to see a video about you’re management it structure and approaches with managing files and printers.

Another good video 📹

Can you/have you done a deep dive on your printers that you guys designed and use?

Any chance that you ever release the plans or BOM for your commercial printers?

With SLS can’t you nest many parts in 3D without the need for support structures? Removing and recycling un-sintered powder seems like “less steps” than breaking off supports that then need a more complex process to recycle, and you are risking damaging the part. Very informative video that I enjoyed watching, but I feel there are conclusions that are reached without a full examination of alternatives.

Nylon powder is more expensive than the plastic pellets, and plastic pellets also allow for a wider range of materials. SLS prints also need more specialized equipment for post processing (enclosed chamber to contain the dust) and possibly other equipment as the powder is more hazardous than anything produced by FDM printers (especially if equipped with an enclosed build volume). Since this company also makes their filament in house, it's even easier for them to recycle support material as they just need to shred it and toss it back into their filament extruder.

@@rahul38474 Agreed, material input costs give an advantage to FDM for this farm application; but on the other hand, the need to invest in large scale filament production to be able recycle an unnecessary waste stream is a big part of why in the long term this seems like an optimization of a fundamentally less optimal solution. Could Slant apply the same optimizations to powder production / automated powder extraction?

Yes, SLS and similar technologies allow for XYZ nesting, unlike FDM's XY-only nesting. Powder reclamation could indeed be automated, and material processing brought in-house if a company wanted to do so.

@@rahul38474 True but the finished parts are better with SLS than FDM. Higher performance. The energy needed to turn pellets into a spool, then heated to print parts, then again to reclaim is often overlooked. Recycling isn't free. Energy costs, and looking at FDM outputs vs SLS outputs I would rather have an SLS print outsources and an FDM machine sitting on my desk. I think if most people are going to outsource prints, a bunch of desktop FDMs wouldn't be the first place I would look. I would go for a process I can't achieve here at home (or don't want to deal with).

@@mggevaer260 Their most persistent issue I'm aware of is consistent bed adhesion. Either too sticky and won't release properly at the belt turnover point, or not sticky enough, and the print fails immediately. One variation on this is effectively making a belt that's a bed transfer system that the printer treats as a fixed bed, until the print is done, then the belt ejects the bed on to a rack, where it gets moved to post processing. Then again, that gets you into 'more moving parts' which may not be what you're looking for. You may need to make sure you can track where each 'bed' came from on this print run, so that if post identifies that 'one of the printers' is producing sub-standard parts, you don't have to take down the whole line to address the issue, but that's more or less a solved issue already, so.

Experts do what they can within the time constraints that you're given. You can afford to spend more time on things at home but in a production environment people don't care about you learning new skills, they just want their parts printed and shipped to them as quickly as possible and it shouldn't cost too much. That means no or very limited post processing at scale.
