Ironically, it will be YOU all here who succeed in re-engineering these things into units functional enough that one COULD build a printer for the masses. I always check in on this thread because I enjoy watching you all take products that are still in beta- as far as I am concerened and turn them into functional machines. Maybe I deal with the public more often or intimately than some of you but I can tell you that you gents are not the norm. I'm sharper than your average bowling ball and there are scads of discussione here that I sometimes read a few times just to remind myself that they had been typed in english. |

--- Quote from: BadMouth on March 14, 2022, 04:35:27 pm ---The only technology I see as a possibility is PolyJet. InkJet printer style nozzles deposit resin and are followed by a UV light that cures the resin as it is deposited. If an affordable desktop PolyJet printer could print three dimensional objects as well and as simply as inkjet printers print photographs, then we would have something. This isn't a new technology either and the price would have to come down tenfold before even hobbyists mess with it. --- End quote --- The latest craze in sign making are the printers which use UV curable "ink". The major issues with the earlier printers are the solvent -based inks, which are nasty to work near, but which also quickly dry up on and around the tiny print nozzles, leading to clogs and very costly repairs. The UV curable inks are much slower to dry, and really only do so fully in the presence of UV. They are already printing multiple layers with the machines for raised lettering you can feel, which also increases durability and fade resistance. The problem is that this technology is SLOW as the head must use raster motion algorithms to lay down the tiny layers. Obviously, the smaller the layer, the better the quality, so something like this may be worth the wait. I have no idea if this already exists, but an interesting machine would be one which uses a UV curable resin "goop" which can be accurately dispensed from a nozzle and subsequently cured by UV to create the layers. However, unless the "goop" is sufficiently stringy and fast curing enough to deal with unsupported overhangs, without negatively affecting print quality, then the method wouldn't be very useful. "Goop" also tends to easily trap air, so it would need to come in vacuum treated and sealed pouches, and a certain amount would need to be expelled when changing or adding resin, just to make sure none got in the dispensing path. That's just one possibility which borrows from current (old) technology and blends with it, something newer. Just removing the heat and thermal breakdown from the materials would go a long way to alleviate the current issues with FDM (which it technically would still be :) ). But this seems like an unlikely path for the technology, as SLA printers work much more efficiently and results would be limited in the same ways due to the current state of resin formulation. The good news is that technology is actually pushing forward on this front, with new and better resins being formulated at a pretty good pace. This is why I believe that SLA (or similar) technology is the future of 3D printing. Simpler operation, less moving parts, better results and a more viable path moving forward for achieving durable and genuinely useful parts. |

Come on, you know that technology is constantly improving. E3D has just come out with a nozzle that you can change with your fingers, no tools or fear of burning yourself. Technology advancements and improvements like that will benefit consumers 20 years from now. http://forum.arcadecontrols.com/index.php?action=post;topic=152421.1200;last_msg=1753359#postmodify --- End quote --- The catch with these is that unless they are WIDELY accepted, the cost of these types of systems will be prohibitive. A 49 cent nozzle which works fine in the hands of the actual enthusiast will prevent that wide adoption when the alternatives are 100x+ more costly. In 20 years, I find a much more likely scenario is that FDM printers are relegated to history and will be supplanted by something more capable and user-friendly. As I mentioned earlier, FDM is literally built upon a 70 year old concept, which just happens to be one of it's majorly limiting facets. --- Quote from: nitrogen_widget on March 14, 2022, 01:21:57 pm ---compared to my chiron the vyper feels like cheating. i just finished a 54 hour print. no issues. with a cura profile off the FB group. i'd recommend this printer to first timers. --- End quote --- And that's the FDM rub. Amazon reviews (taken for what they are) show the Vyper to have ~25% of reviewers being somewhat to terribly dissatisfied with the purchase. And it looks like a very nice printer! While some of that can be chalked up to manufacturing issues, which should only be a few percent, there's still a lot of "not happy" purchasers. I believe a good chunk of it is nearly impossible expectations given the technology in use. I've actually had a change in thought. The fact that just about every printer at a price point is nearly identical nowadays, it gives a good indication that, for the money, that design delivers the best possible result. Unless one has mushrooms growing between their ears ( :) ) I think a good recommendation would be to jump in on one with the least negative reviews for manufacturing issues, play with it and learn it well. Then, if the hobby is found to be enticing, begin doing the upgrades yourself to turn it into a better printer. Because the models are so similar, there is an abundance of inexpensive options for upgrading it to a very good printer. And doing it yourself means that if you need to fix something (you will) you will know right where to go and how to do it. Everyone else should throw money at it if available. :) --- End quote --- I will say the most common problem with the vyper is the strain gauge which is used for leveling can break way too easily if the printhead crashed into the bed or a print. i'm the type of guy who drops his fricken build plate into his resin printer's vat wrecking the FEP and the screen so i ordered a spare. sometimes they do come broke from the factory and almost all of the anycubic fdm's suffer from loose fasteners. i belong to the FB groups where people post their problems and 95% of it is user error / ignorance on how these printers work. 90% of their problems is bed adhesion from not leveling the bed. very few of the people who have had problems legit had a bad part or dead board on their printer. it comes down to people seeing pretty pictures of prints and not understanding it's a PITA to dial a printer in to get great prints. usually. i'm still amazed by the vyper. lol. I just bought an aquila fdm for $100 in pieces. that's almost half price. it was a return. it looks like the person who bought it couldn't assemble it. it was never heated up with filament in it. that much i can tell. could be a dead board. :) i'll find out after i finish replacing the wire harness on my 3yr old chiron. :lol |
