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.

Maybe you can answer my doubt. I'm sure I once saw a manual pellet injection molder in a factory that wasn't connected to electricity at all. I guess the pellets melted by friction. The cycle was about 5 seconds per injection. I have been searching for one to buy and can't find it. Is this a real thing?
@BelviGER

@Malakawaka highly unlikely that it was entirely unheated. While the friction can be enough to melt the material once it is in motion, that does not apply to all extruder And once you turn it off you will have to find a way to heat it again It could be heated by steam, hot oil or whatever though, not necessarily electricity.

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.

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?

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.

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.

While the layer lines will always be noticeable when printing at a 2 mm layer height, they were particularly obvious with this recycled PETG filament, which contained contaminates that would randomly die some of the extrudate.

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.

To address the umbilical retraction issue, simply install a collar on the ceiling in the right spot ( as high as possible) and move the retractors away from the collar. Ensure that the retractor is sufficiently long when fully extended to accommodate the extra length so that you can eliminate the slack up to a point very close to the ceiling.

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.

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.

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.

@@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.

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

it's impressive to watch it do the first layer. It looks like a line of toothpaste. Would a pair of CPAP help as a cooling fan?

So part cooling has been kind of a headache... A lot of air flow is needed to cool those thick layer lines on overhangs and short layer times, but I have found that running the fans at max speed near the bed can lead to adhesion issues even for PETG.

What is the biggest nozzle size that the printer can print with?
@DrDFlo
3 ай бұрын
The major external diameter of the stock nozzle is about 20 mm, so it definitely has to be less than that. However, you can always over-extrude. For example, you can have a 10 mm nozzle orifice but print 20 mm "roads"

What do you use the raspberry pi for? And what direction should I go to for using an interface for the duet to control the temperature with the corresponding slicer? (Also, what slicer are you using?)

0:48....vulcano cht nozzle = 70mm3s: super vulcano with dual vulcano cht inside (one "nozzle" without the tip act like a spacer) And you have almost 200mm3s (but try to keep it hot...in reality more like 150mm3+) It is possible to use multiple spools at once (few extruders , few heating zones , single nozzle...like in old multi colour nozzles ) to go over 500mm3s easly for pretty cheap , but it will be behemoth of a hotend (dont ask me how i know that , lets just say my smallest oldest (10y+) printer have 500mm+/- xyz and printed molds for composites)

You are over complicating your over head problem. Just add a low profile pulley to change the direction so your tensioner can be placed horizontally and not directly above the printer. With the direction change you should only loose a few inches of over head height.
