Or even make a block and tackle out of the tension cable if it has length that’ll do it for sure lol so it would loop around its current mount point seen at 29:08 then up to the retractable spool with a pully wheel ore metal loop there too then back to where the other bit is sagging

A little tip on soldering those cup terminals: The easiest way to get a perfect joint every time is to tin the wire, then heat the cup from the side, melt it full of solder, stick the pre-tinned wire in and let it cool. If you want a visual guide, I believe the PACE soldering tutorial showcases this method.

Very nice cabinet build! The "big enough" cabinet doesn't exist. lol. Brady also make Permasleeve label rolls (heat shrink tubes), which are really nice for signal connections (pricey, but nice. I still use the self-laminating labels for bigger diameter wires though). Something you might want to consider are pluggable MOVs/surge suppresors. I had one of my Mesa modules destroyed by a lightning strike (and can only presume it came through the DC power supply). ProSurge SP150 or similar are fairly inexpensive. My cabinet is connected via a dedicated 30A/120V circuit using a circular L5-30P connector, so can't use a typical surge protector. The Omron E5CC series (specifically: E5CC-QX2ASM-802 or similar) has the same form-factor as the AutomationDirect temp controller modules, but they support full RS-485 control. I got a couple off ebay a while back new-in-box for around $120/ea (just make sure you double-check the part number -- most for sale don't have RS-485 support). I know you already fixed the temp issue -- but they are pretty cool if you need them in the future, and they support all types of themocouples, RTDs, and PT100 probes. AutomationDirect's "standard" temp controllers also support RS-485, but haven't looked into them too deeply.

@karlh6692 12 күн бұрын

Have you looked at extruding filament on demand? The print head could still use a filament but the pellet extruder is a bench top machine making filament on demand. Since printing uses variable flow an accumulator for the filament could be used. It looks like a rope block and tackle but it is on a sliding frame so you move the pulley sets (block) in and out to accumulate filament. (See if you can spot the guy who did a school science project at a nylon carpet factory). It would be a great add on for filament hungry printers. A cheaper method would be to make 100kg spools and just use a motorized decoiler that is triggered by the sag in the loop between it and the printer. much like the decoilers used in sheet metal stamping machines. Are you using the helical rack and pinion slides?

@djjudd566 11 күн бұрын

Also, with that amount of molten material being extruded, you might could benefit from chilled air from an air conditioner or chiller to blow across the bed (or if you're feeling up to the challenge, directly from the cooling fans on the nozzle.) That way you would have sub-ambient air blowing on the print.

i think your over cooking the plastic ,you pumped too much heat into the plastic that its boiling and bubbling and the 3 fans cant take the heat out of the plastic before it deforms. try more torque with less heat . also you might have a "bigger is better " problem, 20k is crazy for a 3D printer , i dont know if this is your extruder or if its a review unit but you can probably drop 2 Kg or more if you remove all the useless metal sheet and connectors off the extruder awesome video .always glad to see what crazy thing your up to.

When I crank the metering/nozzle temperature zone up to 230-240C, you can clearly see that the material is degrading (significant voids and off-gassing). However, the planter was printed at 205C, and really there was no other signs of degradation. However, the recycled plastic feedstock is quite contaminated, there are black specs and small pieces of cardboard/wood that I have been unable to completely sieve out. It could be this material that this burning in small quantities, but I am still not convinced it doesn't have something to do with the humidity in my garage and the ease at which polyesters absorb water.

Hi there! I am following your videos on this huge printer… and, please try to not get upset with me, I ask myself how much you invested already in this machine… and beginning to be skeptical if it will print nice at some point. 😳 It looks an insanely cool project - but in the end, how it prints is what matters, right? Have you printed a Benchy this size on the OrangeStorm Giga?

@DrDFlo 12 күн бұрын

You don't think the corner flower planter looks nice?? I joke... but yes, the benchy doesn't look particularly nice, but you can't compare it to the Giga. That benchy weighs 7 kg (15 lbs), which would cost over $100 to print on the Giga and take over a week. The recycled pellets were only a couple of dollars total (but were contaminated which led to some of my problems). The benefit of pellet extruders is massive flow rates and cheap feedstock. The drawback is resolution/detail. For large objects like the planter and my boat that is currently printing, quality is about what I expected.

@GeekDetour 11 күн бұрын

@@DrDFloFair enough… but the extruder itself is extremely expensive: 20k dollars 🤯 Is that right? (That would buy a lot of filament). And SO massive/heavy that printing directly from it in the print-head will be a limiting factor in speed/acceleration/stability. Maybe it would be possible (although very tricky to control) to use it on top of the printer to fabricate the filament you use - on the fly - and use a much smaller and lightweight printhead to actually do the quality print. You will still discover if clients (or yourself) will be satisfied with such irregular prints - even though they are massive and arguably cheaper than with a different setup. Maybe manufacturing your own filament in house would be the solution for having a huge printer - not necessarily making it happen in the printhead itself. Good luck my friend. I am skeptical - but I find it fascinating nonetheless. ❤

What about a bowden fed extruder that melts multiple filaments out of one nozzle? 5mm filament has a cross sectional area of ~15.7mm2. 2.85mm filament has a csa of ~8.95mm2, 1.75mm filament has a csa of ~5.5mm2. To match or exceed the 5mm filament csa you would need 2x2.85mm filament feeds or 3x1.75mm feeds. You could roll your own filament from pellets or buy it.

I don't know if this extruder or the control software you use would support it, but would you be able to use a shut-off like what is used in injection molding machines? It would prevent most stringing and may be able to help with pressure drop from constantly stopping the screw, especially if this extruder has a pressure sensor the control software could use. I kinda wondered if you would be able to use this for injection molding, but without a retracting injection screw it wouldn't get a high enough injection speed, and you would need a lot more down force than this setup would allow.

You say that pellet extruders can have issues with small moves due to the need to build pressure. Could this be fixed by decoupling the requested flow rate and the screw motor? If you had a way of sensing the pressure in the nozzle then maybe you could have the nozzle pressure controlled separately from the flow rate requested by the Gcode file. Or maybe some changes to how the slicer works to allow it to compensate for the screw extruded and continue spinning the screw between moves.

As amazing as this thing is, it really upsets me how expensive this is at over $22,000, even if it's geared for "industrial use." It's not just "Massive Dimension" pellet extruders that cost so much. It seems to be industry-wide with some costing nearly $100,000. Maybe it's a bad comparison, but at this price, I could get a brand new car like you suggested. A car has significantly more technology, more parts, engineering, raw materials, and overhead that went into manufacturing them. Can someone explain the cost breakdown for these things?

@DrDFlo 9 күн бұрын

Usually, it's an economy of scale problem. Let's say you're an extruder manufacturer, and it costs $5,000 for you to buy all the off-the-shelf and custom components plus labor for assembly. At $5,000, you are already priced out of the hobbyist market, and that doesn't even include the normal overhead to run a business (warehouse space, customer support, marketing, and salaries). Further, the extruder you're manufacturing is heavy, so an industrial motion platform is needed to move the extruder (robotic arm, bridge-style gantry system, etc.). So even if you could sell your extruder for $5,000 or let's say you sell it at a loss for $2,000 and plan to make money by selling plastic pellets (which is hard to do because pellets are everywhere and not locked down like say printer ink), there are very few people who have the means to afford this setup. So if I were doing the market analysis for this company, I would say we target the R&D industry. Create a cushy margin, say $15,000, and then we only need to focus on selling 50 units a year. I can then spend time going to trade shows and other outreach to market the extruder. Further, I can provide really good customer service to match the price tag. Obviously, if you set the price too high, then potential customers will just build it themselves.

in FFF they are called Daughter boards

I wonder how many sales of mass dimensions gets from you making a video like this. But obviously there are sales otherwise they wouldn't keep upgrading your printer.

Buys a high flo 3d printer for printing a flower box. 38mins on this... a timer on the print bed and handling of the prints would be nice to include in the video.

Lol the planter was just a test print that made the wife happy... I needed to make sure the extruder could perform consistently without creating voids, which would sink my next project (pun intended!). But the print settings for the corner planter were the same as Benchy - sparse infill = 180 mm/s, exterior perimeter = 50 mm/s, and internal perimeters/solid layers = 75 mm/s. The volumetric flow rate with a nozzle diameter of 3mm and a 2mm layer height for each feature is 5 kg/hr, 1.38 kg/hr, 2 kg/hr. My apologies this info wasn't readily available

Why don't you print your large electrical cabinet with your enormous printer??

@DrDFlo 12 күн бұрын

Plastics are thermal insulators (more likely the electrical components will overheat). And with the power that the printer is drawing you want a proper ground to the enclosure in case there is a wiring issue. However, for future smaller projects I will definitely be printing enclosures!

@@DrDFlo you are absolutely correct. It also doesn't provide EMI shielding. But for the right application you can add filtered air inlets with fans, an aluminum backplane and even a proper shielding mesh if it is needed. Another great application for a large format printer could be bespoke cable management solutions or at a minimum printed "panduit". I look forward to seeing the next step in your process.

20k for that ???? I work 10 years in the plastics industry and that thing is a damn scam. Almost everything from 3D printing is actually extremely overpriced or actually a scam
