Form factor refers to size/shape/specs. Are you saying this is a size that has been missing from the market? That there isn't a 180^3 printer available? That we are unable to print in this size with the current limitations in the market? That this shape (same as other printers, mind you) has been missing. Or that the specs of 180x185x180 have not been met by current offering in the market. I think I can print EVERYTHING this form factor prints, on any of my printers that measure at least 180x185x180. Only thing it won't do is print them upside down, unless I flip my machine over, which is as dumb as this.

@@ogpennywise what other machine has this Form Factor? You are purely looking at print build volume, that’s is NOT the full picture. I recently took a Voron 0.2 to RMRRF. That has a 120mm cubed build volume. It requires a pelican case that is 4 times the size of the one that the Positron fits in, and I had to pay to check that bag as it was too large to fit in overhead bins. On the way back from RMRRF Nomad and I were on the same flight home. He carried on the Positron and stowed it in the overhead. My Voron went into the checked baggage and cost me $40 to check it. It was also out of my hands and I know it was treated rough on its journey as the Kirigami bed frame bent on the way home. No other machine with a 180 cubed build volume will transport as easily as this in my experience. This form factor is in a class all its own.

Saw this at reprap show... thing is pretty cool

metal wire spot electro-plating 3d printing (copper, zinc and others, like silver) is very interesting too, in an electro-plating bath, like copper sulphate water.

I’m so excited to see this coming together finally! My question to the dev team is if there any plans to improve part cooling, I can see the tip of the hull curling up(down?)? Also, will there be any kits available without the case or the screen and cm4? This could easily fit in any usual carry on bag, so the case isn’t really needed. Since the printer can also be operated over the network the screen isn’t either and if we already have a pi for klipper, neither is the cm4. If those could knock off 100-150 monies off the price it’d be really cool. In any case good work team!

The cooling issue is primarily a problem with profile tuning, we're still dialing that in. We are also experimenting with a cooling duct redesign. So rest assured this is something we are aware of and are working on even now. As for units without the pelican case, it's going to take a while, probably going to be a few batches out before we start selling kits with select parts not included.

Would be really cool if they just powered it from USB PD especially now that 140Watt bricks are becoming more popular and 240Watts is ratified and possible though uncommon. Imagine the speeds and feeds and ease of use of this thing powered by the 28 volts of 140W or 48 volts of 240W.

You got it, ha. Also deflecting the heat / airflow from the heatsink from blowing onto the part and unintentionally cooling it I'd imagine is a partial factor. And I don't own this one, it is Nomad's BETA unit. I will be building one soon-ish hopefully.

The only thing I don’t like about it is the Klipper screen setup, just a single usb cable connected and the printer cannot function without it and would stop functioning if it got disconnected, this is definitely a concern with a screen that seems to be intended to get picked up, held and put where you want it. Even just a point where it clips onto the main body of the machine so it can’t get moved about or pulled would be good, or even better would be to have a retention mechanism where the cable is difficult to remove accidentally. Best case would be to use some kind of locking connector.

@MandicLabs

2 ай бұрын

Printing upside down is a function of the compact nature / foldability. To have a "regular" toolhead would require far more rigidity & complexity in the design. This design allows the printhead to always be in the position it will be, even when the Z axis is folded down. That provides a much more compact (lower center of gravity too) design that doesn't require major reinforcement that would balloon its size & weight. It is meant to be a portable printer. Any additional parts & construction takes away from that so they have to be very mindful of where design elements are at all times.

Was wondering why there isn't any updates since the original printer by Kralyn came out two years ago, and now we have a production model? Wow!

Alan, am I correct in assuming the tool head will tap one of the nuts on the idler pulleys mounted on the linear rail to home X? It’s been awesome to see this project improve throughout its development and I’m sure with LDO on board it will be a fun build. I think two of my favorite features are the bed’s interface for the heater/thermistor and the whole motion system. The tool head itself seems a bit large but the weight sits down low on a carriage rather than up high on a gantry so I’m assuming it’s responsibly stable. Great video, this is probably the most detailed overview of the Positron I’ve seen up to this point, extra credit for crispy B-roll.

Yep! You are correct. We mount idlers to the bottom of the X rail by using standoffs as nuts on the top, and the idler screwing in from the bottom. This acts as a rail stop, preventing the carriage from falling off, and allowing for Sensorless homing with its resistance.

Consider this: a voron 0 kit will set you back a similar price if not more and will have only 120^3 print volume and arguably a printer at that volume and price IS a novelty as you’re very limited to what can be printed in it, I have one and I know. For people who travel and need to prototype on the field, granted not that many, this is going to be a tool, for the rest of us it could just be a very cool project to work on, just like the v0, even if not the most practical. But then, consider the potential here, how a printer with p.v. similar to a prusa mini or an a1 mini can now fit in the spool box of that printer. If I had to draw a non printing parallel, I’d suggest considering how mobile phones used to be larger than even wireless ones at the time, then they got small, moved to smartphones and now we have phones that are all screen, barely any bezel. We both reduced the foot print of the device and maximised its interface. Consider this the flip phone of the printers. If anything this printer will be a step in that direction, at the very least. Furthermore, if this was to be a commercially available product like an Ender, the logistical cost from the shipped kits’ volume, along with the per unit carbon footprint, can further reduce the price and make it more environmentally friendly. If you’re still bothered by the price, note that ldo ships high quality components, not necessarily the most cost effective ones. It’s be safe to assume an open source project like this will be adopted by other companies offering kits at lower prices, with respective quality. Lastly, it’s a fresh platform for the community to innovate on. There is great potential here, even if it’s a niche product now, but so where desktop 3d printers a decade ago before prusa gave us the i3 design. Then creality lowered the entry barrier to FDM with the ender 3 and their massive production line benefiting from its scale. tl;dr: It’s not for everyone, but it’s here for everyone to benefit from.
