Anycubic Photon Printer Owners 造訪社團 » 用戶發文

As Robert Daubar posted a link to NASAs gallery of 3D-models yesterday, it reminded me of a project I made last year. It is a model of the TESS satellite in 1/87 scale. The model was made for Norsk Landbruksrådgivning, a Norwegian agricultural consulting firm that was making an exhibition model to show modern agriculture with, among others, GPS-steering of tractors. To show this they wanted a scale model hovering above the diorama.

I have now been printing scale models to nearly perfection for a long time with only minor problems. Suddenly I have started having trouble with printing reliably. As you see in the pictures, the print stops after about 5 mm for parts of the models, then continues later on and somewhat made an almost OK print.

In this print, it stopped for the support on about half the model, while the rest of the model printed fine. On other prints, only the raft printed. However, yesterday I suddenly had a perfect print again.

I have printed 15 of the without problems earlier, so I know the settings and support works. I have tried with Siraya Tech Blu, Prima Light Grey and Prima Black.

I have also tried three different firmware version, 4.2.5, 4.2.19 and 4.2.11.

The files are sliced in ChituBox V1.5.0

Do you know what the problem might be? I ordered a new Photon a little while ago, so I will soon have a (hopefully) working printer, but the plan was to have two printers. I was thinking about fram shearing, but I haven't read enough about it to know if that is the problem here.

I have now used the photon since May, and thought I could share some pictures of my setup. I have been doing quite a few changes to it, but I now have a setup and routine that works good for my needs.

I have gathered everything related to the Photon in a closed cabinet which means that all the mess stays inside here and is easy to clean up. I also have a small fan connected to the cabinet that pulls air directly outside.

I have mounted a LED lamp in the ceiling of the cabinet, and made a simple mechanism that turns the light off when the door is closed so I don't forget to do that.

I mainly use the Photon for scale modeling.
I hope some of my solutions here might be used as an inspiration for someone out there.

Hi, guys. I am printing some scale models of agricultural equipment in 1/32 scale, but having problems with shrinkage that bend the parts. I have asked a similar kind of question earlier, and that solved most of my problems, apart for these models. I am afraid it is the shape of the models that is to blame. If they would have had a bar at the bottom to hold the two vertical beams together, it would probably not be a problem. But since the "real" equipment is like this, I also have to make the model this way.
The parts are perfectly straight after printing and curing.

I have tried this:
- Curing with supports in place, then painting as quicly as possible to prevent more UV-light to cure them.
- Warming the parts with a hot-air gun and straightening them out. This works great a while, but after some hours it's back to a warped shape. I used a jig/mold to make sure they got perfectly straight.

I am using FTD Industrial Black. 0,035 / 7,5 / 4,5 / 50 / 8

I wonder if it might be the paint that affects them?

Hi, could anyone see what I am doing wrong? On all my prints with Fun To Do Industrial Black, I get some loose film that attaches to the model on different places. You can see it in the first picture. The film is really thin, and is annoying because it can be hard to remove from details.

Also I get some thick layer lines here and there, as you can see on the Deadpool bust. In this example, I think it might be too little support causing it.

I did a calibration with the newest files. Is it correct that column 5 is what I should be calibrating after?

I have been doing 0,035/10,5/0/50/8.

I will be doing another test of a Deadpool bust when I find out about the settings.

I have now been using the Photon for a few days, and I have some questions that have come up. I will mainly be using it for agricultural scale models, and during testing I have experienced some shrinking that distorts the model after printing. This causes the model to bend and then crack on the outside of the curve. I have attached some pictures showing the problem. The supports were cut away after printing and curing in the sun for 3-4 min total. I turned the model several times trying to get an even cure.

Some info:
Resin: Fun To Do - Industrial Black
Exposure times: 10,5/6,5/50/8 (normal exposure/off-time/base exp/bottom layers)
Printing angle: Tilted approximately 35/35 degrees.

I have a theory that the front side of the model (inside of curve) has cured more than the backside (outside of curve). This would cause the front side to shrink more than the outside, and therefore causing the backside to crack. Am I on to something?

I have ordered an UV LED-strip for building a curing chamber, but haven't gotten it yet. This might make it better.

What can be done to prevent this in the future? Will it help to spray primer on it straight after printing, or leaving it in a dark place until I can apply primer? The models will be painted, so adding primer has to be done anyways.

Sorry for a long post, but hope I have explained it good enough. I have of course searched around for the problem, but there are many similar kind of problems, but still a bit different than mine, so therefore I ask here.
