MASSIVE Resin 3D Printer! // Emake3D Galaxy 1

The Emake3D Galaxy 1 has made OVER $1,000,000 on Kickstarter - WHOA. I've borrowed it for a bit, and let me tell you, it's quite a LARGE machine.

Thanks for all the content sharing and the discussion in the Emake3D community, Joel! We really appreciate these!

Regarding the questions mentioned in the video, here is what we can tell:
1. Dimensional accuracy can be corrected by software, not to print 25um details, but to print models with a dimensional error of 25 um.
2. Permanent leveling means that the printing platform has been adjusted before leaving the factory, there will be no deviation after adjustment, and there is no need for leveling in the hands of customers.
3. That button below the screen is the pause and stop printing button.

Regards

I'm curious if I'll be correct on the resolution thing, but this is purely a guess. I imagine they can move the 80μm in 25μm increments. So while this smallest individual pixel would be 80μm, they could do 105μm cleanly, whereas an 80μm resolution would overshoot it to make 160μm.

You printed it in that thing? You're braver than I thought😎
Seriously, that is a sweet print.

That laser system is straight out of a laser printer. nice idea using what is 40+ year old technology in a new way. I made a laser display using a few of them you can get really nice "flat" beams

[paulpardee]

Joel, my brother, get thee some eye protection for the isopropyl sprayer! You don't want resin-contaminated alcohol in your eyes, and the specs aren't adequate coverage.

On a side note, I'm a little sad that safety glasses aren't called peeper keepers.

[jurgenvren]

The details that machine did on the "millennial falcon" is insane

[howardbartlett]

For the resolution issue, I think they meant that the laser has a positional precision of 25 microns for that 80 micron spot size. This isn't exactly the same as resolution, but I could understand the confusion/terminology change on their part. It is similar to how an FDM printer with a .4mm nozzle can easily achieve tolerances below +-0.1mm because the motion system is able to control the position of that larger "spot" to a higher precision than the nozzle size. This means that the minimum feature thickness on the machine will certainly be that larger 80 micron (larger because you will get small amounts of light bleed with any true laser SLA printer). However for thicker walls where laser passes can slightly overlap, the final part dimensions should be pretty close to that 25micron precision.

It works kinda like a CRT.

Ingenius.

Thanks for the review! I know you didn't have much time to get the video out before the kickstarter ends. I am currently backing it primarily because I am in the market for a larger resin printer, and bar any major defects, the early bird pricing is a very good value for what it is. It seems like at this rate though we may not be able to get more information on the larger laser add-on, really wanted to see how it is to change it and whether it speeds things up as advertised.

@3DPrintingNerd While I cannot speak for eMake, I can say that the laser spot is commonly larger than the resolution on SLA printers. That is partially because the center of the spot is more intense than the edges, and the resin is cured by intensity and duration. In other words, a short burst from the laser will not solidify an 80 micro meter spot (The center may solidify but not the edges), but a long duration burst will solidify the whole spot. A medium duration burst may solidify the center and gel the rest of the area in the spot, so that an "anti aliasing" effect is seen.

2:13 slightly better explanation: it works exactly like the laser setup in a laser printer (even looks just like one). the beam is reflected off of a constantly spinning six-sided mirror to create a repeating scanline along one axis, with the beam being switched on and off to create the print pattern as the printhead moves back and forth across the resin along the other axis.

High five Joel, this machine looks awesome. I'm glad you shared that. I just love the amount of detail resin printing achieves.

[darknimesis]

Listing to you pulling the supports off made me giggle.

[Trashalchemy]

Another game changer from left field if this company delivers.

[Drakonaut]

I wish I could've backed this, but I already ordered a Snapmaker Artisan, and my workshop still doesn't have insulation for sensitive machines like Resin printers. Love that a video is out to see it in action

[carlosfrostygreen]

This looks fun it looks really cool thanks for resin print videos last year

[PilgrimofMatter]

Where did he get that metal tank to rinse off the model in? Thanks! :)

[DimensionMachine]

I am so glad that I did not back this thing. I was so close to pulling the trigger, but there were too many unknowns for me and emake provided some really sketchy answers online. After seeing the output I am really glad I did not buy one! Thanks for the vid!

"just listen how well those support come off" comedic genius whoever edited this

[frankperez]

Where did you get the container as your wash station?
