This was actually my second 4K printer, and fifth Longer3D printer I've ever got! All my resin printers have been from Longer3D, and so far zero issues during my 3 years of resin printing :)

honestly the best and strongest 3d printer I've had. The Z axis is great.
I am doing tests, because the resins with which I work do not give the basic parameters, in France this printer is not very well known, probably not enough publicity, what a pity for the others.

I love it! I have made everything from costume pieces to miniatures war gaming terrain, and I keep running across new things to make. The detail is great, and it the cost to operate is very reasonable.

Magnifique machine
Conception trs robuste
Ecran protg
il ne reste plus qu' la tester

Amazing Printer !
Wonderful results event the first tests !

Fantastic printer! This thing reeks quality and I can honestly say these guys were paying attention to detail. The dual slides on the X-axis are rock solid with zero wobble. No layer shifting here! The fan is quiet and seems to do a good job of keeping everything cool. I installed a flexible magnetic plate on the build plate and didn't need a spacer because of the 4-point leveling attachment.

I printed a couple of test models to dial in my settings and dove into a large multi-part model (18 pieces) I bought a few months ago while waiting for my shiny new printer to arrive! :) I'll post pics once with assembly.

good

I have never owned a 3D printer before but with the resolution of the Longer Orange 4k I had to own one. I am still learning and had quite a few setbacks and problems getting things working but it wasn't due to the printer but my skill level. The test files all worked well and learning to use Chitubox was the problem, but after a few tries I have the hang of it and it is printing beautifully. Longer customer service has been great and really responsive to my questions. I will stay with the Longer family as they upgrade to new resin models. Here is a video of my Longer Orange 4k color being unboxed: https://youtu.be/83UpbEAB8j0 a few days later I was contacted by Ryan from Longer about the shipment of my mono screen upgrade that I had ordered. It was nice to see they were being proactive in completing my shipment without me having to follow up with them. Thanks again and look forward to many more prints with my printer.

Я очень доволен этим продуктом. Качество печати на высоте. Нужно обновлять продукт до большего разрешения. Сейчас минимум актуально 10-12К

I own both the 10 and 30 I would love love love to test the 4k the 10 and 30 are awesome printer though.
