Anycubic Photon Printer Owners 造訪社團 » PETG

Dear Photon-Masters, I have a couple of questions to put to the group. 1) Is there a resin which is not so brittle, similar in strength to say ABS/PETG (rigid, but with a little flex) 2) If you have said resin and experience printing with it, is there anyone who would be willing to print a couple of parts for me at a reasonable cost? I'm based in the UK. They are Y rod holders for an FDM printer I'm building and my other printer is out of action. Thank you!

I just finished the heater!

Originally I was thinking of making a 'Photonsters PTC Heater Unit', but it was a bit tricky to get parts from where I live, so instead I disassemble a $16.15 small heater to get the parts I needed.

The circuit of this mini heater is very useful because it has functions such as timer, fan speed control, temperature control function, and voltage conversion.

The case was printed with PETG, and the bent part was not melted by the heat of the heater but because of the failure of the middle of printing.

Compared with 'Photonsters PTC Heater Unit', it is slightly bigger.

Hi guys, just unpacked my photon and thinking about some "odour control" parts from thingiverse (already purchased carbon filters) ... have you some recomendations ? What material you did use for theese parts, it is PLA fine or is better to use PETG (really dont like ABS O:-) ) ?

I've had more success with the molds.

I switched from the Anycubic resin to a grey, heat resistant resin. It can take up to 160˚c- Though not really required for urethane, it does warm up a little, so I thought it wouldn't hurt.

This particular mold is for a part that I manufacture. Until now, I have been making them on FDM printers. It is a mechanical part, and they have to be printed out of PETG, and they have to be ALMOST solid to be strong enough. It takes me about 1 1/2 hours to print one.

The cast urethane version takes about 15 minutes to make 4. And, It's MUCH stronger.

The mold is made up of 3 main parts, and 4 "inserts". The inserts form the end that connects to the motor shaft- which is round with a milled flat. The connector just slips on.

I printed the molds at 0.05mm resolution. The two outside parts are one print, and the middle is another. They take about 12 hours.

Both came out perfect on the first try- Other than removing the supports, there was almost no post processing. I even got to use my new curing setup!

I bolt the parts together, tighten them up, and pour the urethane. 10 minutes later, I have a finished part. With two of these molds, I'll be able to crank out LOTS of these parts. This printer has paid for itself in the first week I have owned it!

I have created a video showing the results of comparison tests for strength between FDM printed objects (PLA, PETG, Polycarbonate) against Resin printed objects (using ANYCUBIC Clear resin, Sparkmaker LCD-T resin and Siraya BLU resin.)
I was surprised by the strength of the resin prints. The Siraya BLU was the strongest of all of the objects for pull strength. I used a Photon to print the samples.

Well day one down. Learnt a lot. Thank you everyone! Tried to print a bed full of minis.

The big one circled in red didn’t print ? came off of the supports. Should I have used medium supports? Or just more of them?

I also learnt not to have the base of the model touching the bed haha a lot of them have some of the base cut off. I should have rested the entire model on supports.

Lastly I ran the Prusa and printed a PETG cover for the VAT. Keep it safe while I’m at work!

Added PLA, ABS, and PETG to the torsion tests.

Hint - PLA and ABS beat almost all resins. PETG is strong but too soft for this test. Only one resin was stronger than FDM on this test.

Hi everyone,

I am thinking about buying the Photon, but am hesitant due to a few reasons.

I am mainly interested in making functional parts so have these concerns:

1. Are there any good resins on the market with performance characteristics similar to PLA, ABS, or PETG? Or are they all very brittle?

2. Does anyone know how long prints can last when used outside? (Does extended UV affect them negatively?)

3. Is the first layer flush with the rest of the print, or does it "elephant foot" at the bottom?

Thank you for your time! :)

Hi All,
I try to print out some cards but at the and they are too brittle. Could anybody recommend me some resin that won't brake like glass? Some flexible resin maybe or something that similar like PLA or PETG. They are good materials but my FDM printer resolution is not enough.

Hi All, I recently fired up my photon after over a month of not using it. I have a PETG cover I printed for my resin vat while not in use. I left resin in the vat with the petg cover on it for over a month. Yesterday I printed with the month old resin and it worked perfectly fine, and the FEP sheet seems to be in just as good a shape as ever. I was previously emptying my vat after every use but now I'm not sure it's necessary with a cover. Has anyone had issues leaving the resin in the vat?
