I hate going to trade shows but I love learning about the new technology. Thank you for taking us to Formnext 2023 without all of the investment of our time and money, and without the hassles of traveling. These are great interviews and expositions of 3D printing technology.
Reason for classic heaters: full power across the temperature. Reason for ptc ceramic heaters: typically higher initial power, decreasing power with temperature (safety). So essentially if you are going above 350c, use a standard heater cartridge. If you stay below that, ceramic heater, its much safer to use. It cant melt your heater block in case of a thermal runaway, because firmware based protection can only protect from thermistor based failures, but if the hotend mosfet fails closed, nothing can protect you other than cutting power from the Mainboard.
Your content never fails to impress me. On another note, keep pumpin out the videos PLEASE bro.. im havin sucha hard time today.. my extruder driver went out on me last night so i cant print until my new motherboard comes in :(.. i just cant wait for my a1 mini to get here..
It's obvius that Slice Engineering (SE) copied Simon's VzBot conduction heat break (2:44) and he's plate / adapter. What a shape! If you remember the guys from SE were accusing Simon for copying their "patent". Very laughable
I've heard about the Mosquito Conduct at least in early 2022 (probably as prototype), while the Goliath came out in late 2022 (and the short version without heatsink came out even later)
Not to get too much into a history lesson here, but according to Slice the conduct hotend has been available to its OEM partners since 2020. There are plenty of hotend options on the market, so I guess pick the one you like?
I'd love to put 2.4 nozzles on my Ender 5 Plus and Ender 3 V3 SE. I mostly print props, armour and helmets but also want to be able to produce architectural molding. What do I have to do to get those big fat lines?😊
Regarding liquid cooling, why not employ active cooling such as ThermoElectric cooling instead. You are cooling at the same time adding to the enclosure heat. Just some 💭
I've considered this, it probably comes down to the weight and complexity of a peltier cooler compared to the amount of cooling it provides. Also, as Peyton mentioned, some machines already have water cooling systems built into them, particularly the industrial type of machines, so the water cooling block is just a drop-in for them.
@@NathanBuildsRobots Sincerely appreciate the clarification. Definitely driven by the economics and the retrofit aspects. Also the TE coolers don't handle vibrations that well(since it is low temp bonding of 1000's of bi-metal junctions), apart from the upper limit of operating temp. TE's are not that efficient, with reduced differential between cold and hot sides. The high temp versions are fairly expensive as well. Also they demand much more power relative to the cooling they provide(no wonder compressor driven cooling is still the norm for efficient cooling).
Because it's generally a requirement to use twice as much power to cool a TEC than you can dissipate, with lower efficiencies as temps increase. So you're adding a lot of power requirements, and then you need to cool the TEC, which puts you right back to where you started, but with more heat. There's a reason very few things use them, and a lot of the things that use them are things like bench instruments and small scale test cells.
@@Mr424242424242424242 But in this specific application, the heat output would reduce demand on the heated enclosure!, while still providing the lower amount of cooling needed past the heat break🤔. So, it is just a matter of economy while taking advantage of existing water cooling.
Is it me or do a lot of the companies sales reps look like they partied all night and are all licking their lips a lot ? Lol I could be wrong but I a few of them seem to lick their lips a lot.. 😂
