  • DIY experimental Redox Flow Battery kit

    Jump

  • Interesting project! I will have to give it a look.

    sourcing the materials can be a bit of a challenge

    Any more details here? I'm guessing the necessary material for electrolytic and what not? Do you know about the boring adjacent stuff like measuring (eg how accurate do the measurements need to be, how precise, etc), disposal, etc?

  • For ACM - like aluminium honeycomb?

    ACM is more of a sandwich. Aluminum, plastic, aluminum.

  • We probably have the same model - the one with the big oval stand. Every once in a while I wish it was OLED and/or higher resolution, but it's not worth the expensive or all the modern "features" such as these.

  • I personally am pretty happy with my 2.4, although I would suggest skipping the cable chains and going to an umbilical. I went the nitehawk route. If you're going to be printing ASA or ABS add an under bed carbon filter and bedfans. I would also suggest skipping to ACM panels if you plan on big ASA/ABS prints.

    If you dig through my comments you can see me talking about it. Mechanical bed leveling, that actually squares the gantary to the bed, and Z calibration make for very consistent first layers.

  • $1,200 is Voron and RatRig territory. Vorons cap out at 350 mm3 for build volume and 500mm3 rat rigs are $1,550. I agree that plenty of folks are probably over buy on printers, but if you want this kind of build volume the price seems reasonable - especially for a printer that ships assembled. Personally, I went the Voron route and if I wanted a larger printer I would probably either just make my 350mm taller or go the RatRig route.

    That said, high velocity on a large format printer isn't that useful for big prints IMO. You're probably going be running a bigger nozzle and laying down wide/tall extrusions, which means you're probably going to be limited by how fast your extruder can melt plastic. That's the case on my Voron with a Rapido HF with "only" a 0.6mm nozzle, 0.8mm extrusion widths, and 0.3mm layer heights.

  • New God tier filament for me

    Jump

  • These units are somewhat silly IMO. It all comes down to volumetric flow. Big nozzle + thick extrusions + thick layers would probably mean needing to print slower than that speed due to the ability of a hot end to melt the filament.

  • Keeping Snap And Crackle Under Control With Prunt Printer Firmware

    Jump

  • For quite some time now, Marlin has been the firmware of choice for any kind of custom 3D printer, with only Klipper offering some serious competition in the open-source world

    Confused Voron noises

    It does seem like an interesting concept, but I wonder how much benefit it will have, both in tuning effort and final outcome.

  • Vibe coding your MFA

    Jump

  • That your company has an in-house software dev team is impressive. Does the revenue-generating business have access to that team?

    Not OP, but in a similar situation. We have in-house dev for both tooling/infrastructure as well as revenue generation. For better or worse, leaders have neglected the software tooling and infrastructure that we use to build and deliver our revenue generating software for decades. Some serious cracks in the foundation showing and we might finally start fixing things.

  • Etsy cracks down on 3D printed products — new rules exclude many 3D printed items from listings

  • And I'll be the first vendor!

  • How do I go about using/having printed purchased files off Etsy? How safe is it?

  • 1 and 5: Either should be fine, especially if the seller is reputable and has reviews. Many sells will have a store on multiple sites, but in some cases people will resell other people's work. See if you can track down the original creator to support them 2: I suspect everyone will want STLs they won't have to do any processing on. What do I mean? Well, I could give you a STL for a piece that's massively too large and would need to be split into pieces or a different STL that will be impossible to print well. I suspect print services won't want to deal with this, will charge for it, and/or you might not be happy with the final outcome 3: If you're paying someone to print the parts, they will likely have larger format printers. However, this might cost some $$ 5: It depends how thick the designs are and how strong you want them to be (more perimeters = stronger), but keep in mind that you're also paying for machine time and potentially processing (eg surface finishing, support removal, etc). To get a feel for a quote without buying this design, find some cosplay armor on something like printables and use that for quotes

  • New Court Order in Stratasys v. Bambu Lab Lawsuit

    Jump

  • I had no idea this was even going on, so that's a potential plus.

    Stratasys filed the two lawsuits against Bambu Lab in the Eastern District of Texas, Marshall Division, in August 2024. The company claims that Bambu Lab’s X1C, X1E, P1S, P1P, A1, and A1 mini 3D printers violate ten of its patents. These patents cover common 3D printing features, including purge towers, heated build plates, tool head force detection, and networking capabilities.

    I had heard that Stratasys was a bit of a patent troll, but some of those claims are news to me.

  • Adding encoders to your steppers, or buying stepper motors with built in encoders, can help a lot but it's not a cheap solution. It can also be a bit bulky, so packaging them a printer not designed for them can be tricky.

  • I also free hand. Every once in a while I wish they were more perfectly square, but then I realize I don't actually care enough to print a fixture and have to deal with attaching/detaching my Weller.

  • Is a Voron 3D printer worth it??

    Jump

  • I suggest checking out this post. I have quite a few replies about the voron experience.

    TL;DR - agree that a Voron can be a start and walk away printer. Building it will take some time, which isn't necessarily a bad thing but know what you're getting into. It will take some configuration and tuning to get it printing, but the Voron initial setup guide and Ellis's print tuning guide are very easy to follow.

  • I designed and made a thing!

    Jump

  • Nice work!

    One of the interesting things about modeling and then printing replacement parts is figuring out which features matter (like shaft diameters and spacing in this design) and which you can take some liberties with to make printing easier. For example, for the part on the left you may have been able to add tapered feature to the rod insider to let you print the part standing on the flat bit on the far left without any supports. Another possibility might be trying to get the part to lie lengthwise by modifying the cylinder some as arced parts have deceivingly big overhangs. Perhaps you could give it a small flat spot.

  • 3D Print ABS Without A Screaming Hot Bed

    Jump

  • The challenge with ASA and ABS re:warping is chamber temps, not so much bed temperature. Both shrink pretty significantly compared to PLA and if your chamber is too cool and/or your print is too big or has difficult geometry you're going to be in for a rough time.

  • I've lived at this latitude in a couple different states. From what I've experienced, the climate in the mid west is similar to that of PA, NY, NJ, CT, RI, etc. Snowfall changes vary radically based on your proximity to a lake and generally speaking anything west of PA is super flat.

    To me, the nice thing about SE MI is it the size of the metro and the quantity of things to do within it. The people are also a bit more friendly than the east coast, which is nice too.
