I like that it comes with a flame detector. I’m assuming it’s there because of the burning with a laser, and thus a potential fire hazard, but every now and then you hear about a 3d printer burning someone’s house down, so maybe it could mitigate against that. How? Good question. Maybe turn off the fans so you stop feeding the flames oxygen? Or does it have stronger measures it can use? Like self-extinguishing, or something like that.
Filtration is extra
Side note, I cannot stop watching this video.

Cool! I presume it’s not just for DIY but that somebody is going to release a machine that leverages those bondtech printheads? Am I right that they look a lot smaller and lighter weight than the Prusa XL printheads?
What does it mean by “contactless”?
If any of the website leaks are correct, there’s mention of a fire extinguisher as an addon at a later date.
Fire Extinguisher is an optional equipment, will be available soon after the product release.

This Bondtech INDX looks great! When watching TeachingTech sovol sv08 toolchanger project, he linked to someone doing simething like that - swaping just the filament path & hotend but leaving the head separate.
Generally I think that’s very promising approach.

Where’s the last teaser photo? I missed it. I thought there’d be one last one today before the big reveal tomorrow.

Goldfinger, this fits - an 61 Year old Movie 
World record in development Gap – from 5 years ahead to technology 61 years behind, the hugest development gap in 2 years ever. Let’s see how this thing performs compared to a $1 million laser with a $0.8 million material changer. It has to churn out parts every second, as it’s a market where the last ones are still smashing each other’s heads for the last order. Maybe something for the Chinese professionals in remote areas, so they can play with lasers there too…
Well already gets the tamp of toy and there really need to come Hugh surprises now……
Thats steep if its for a 10w laser, for less than $100 more you can get a whole standalone Creality Falcon with a 10w laser

I assume the “Laser Kit” includes 10w and 40w, but maybe not
for 40W you’ll be charged 4 times more than for the 10W… elementary, my dear Zammer…

40W is marked as optional in the FAQ, so I think it’s an extra add-on

Somebody said the filtration needed for the laser is also an add-on, but i cant verify. Maybe its only an addon for the non laser version and comes with the laser version.
Well, a laser burns or cuts or erodes etc., depending on the application, the base material being processed and your own taste. So no there is no strict answer on a filtration need.
I disagree. It needs to cover the worst case, or it’s no bueno.

Yeah if theres a machine prebundled with the laser, I’d imagine it should come with the things needed for safety and filtration. Thats a bunch of customer service calls waiting to happen if not lol

The industrial printers such as the Markforged X7 and upwards in price utilize a laser micrometer that verifies dimensional accuracy of the part on the x,y &z axis and will compensate the next layers x, y, and or extrusion flow rate to correct for variances. The suggestion that accuracy will be improved by implementation of a laser, indicates that they found a way around Markforged patent on this technology. Also the visualization of the beam appears to be that of a scanner, not an engraver or cutter. With all of that said, if the laser in the image is used for scanning and automatic correction or continuous correction in collaboration with the new servo motors, this would put the HD2 on par to meat or exceed the benchmark set by Markforged years ago. On the X7 I have printed over 100 prints with only 1failure. The continuous monitoring laser makes all the difference.
Best guess yet as to what would differentiate it from other two extruder 3D printers on the market. A nice curve ball making competitors scramble to catch up (for two years, or however long).
I’d welcome anything that accurately accelerates/automates the dialing-in of a new filament, as that is both time consuming and pure drudgery to do manually with only the tools provided in Orca Slicer.
