Anycubic Photon Printer Owners 造訪社團 » PCB

sooooooo , anyone here use the photon to expose pcb circuit boards for etching?

Hey Folks. I've printing PCB mounts for wierd enclosures on my Photon. Thinking of ways to bond the boards in place. I tried using a drop of resin then hitting it with my UV torch, but it seems like there's some sort of almost oily layer that's forming at the interface between the resin and the PCB and stopping it from bonding properly. I get the same residue if I just zap a drop of resin on a piece of paper/plastic.

Anyone know if this is a normal part of the process, or am I doing something strange?

Ok Folks, so word of the Photon X is spreading and of course AnyCubic is asking for what we'd like to see in the latest version. I've seen many people here asking for larger build volumes (some at around 20cm cubed!) however I feel like this would be a pretty bad idea and here's why:

So DLP printers operate fundamentally different from FDM. Increasing build area isn't as simple as increasing the length of a few rods and cutting a larger PCB. the size of the screen must be made bigger, as does the resolution of the screen. Currently, the Photon uses a 1440p screen to give us the high res results we currently enjoy, but if you then stretched those pixels out to 20cm cubed, it would be incredibly low resolution and terrible print quality.

Now let's say we increase the resolution of the screen to match this large increase. goodness knows how high the resolution would have to be to maintain the consistent level of quality seen with current prints, which would cost goodness knows how much and would likely require their own screen manufacturing efforts (driving the price of our beloved 'cheap' DLP printer through the roof).

NOW what we could instead do, is focus on and improve upon what currently makes the Photon such a great printer. the level of quality of the prints that this machine pops out are outstanding for the price but can, of course, be improved. it's very possible that a higher resolution screen (with similar size) could be purchased 'off the shelf' by Anycubic, allowing them to introduce higher X/Y resolution with very little cost. If this were to be combined with an updated Z rail that prevents wobbling like the eagerly awaited mod on this forum, then I believe that Anycubic would be on winning track to win over the current fans as well as new hobbyists into our community.

Of course there are other features such as larger front screen size, better venting etc that are being discussed, however i just wanted to share my 2 cents on the subject.

thanks for reading!

TL;DR

DO focus on improving the quality of prints at an affordable price by using higher resolution screens 'off the shelf' as well as a better z rail. Z rail could be lengthened too to allow for taller prints.

DON'T focus on wider build volume. bigger screens will mean little to no jump up in X/Y resolution. Resin is expensive as it is, if you want BIG prints then use FDM or cut your parts up to save all the litres of expensive resin.

Hey Guys! hi everybody! I have something like an issue with the printer. Somebody get noticed that mayeb our Photon printer has static issues. Somebody had resolved this? Here is my story I was trying to improve my printings and I was leveling by second time plataform and I decided to print this https://www.thingiverse.com/thing:3096818 well I put and everything went fine I put the new Z=0 very easy bla bla bla but Oh! suprise when I raise the plataform 10mm I saw a little spark bettween the screw and the left side (where you can see anycubic logo) after that I thing the static discharge reach the optic sensor because the sensor got resetted.

I tested to put the original parts of the printer and it's happening the same but I can not see spark logically because of the stock parts has more discreet screws.

So I think this printer doesn't have grounded properly.
This issue can cause random resetting or burned PCB becuase sometimes the discharge can reach all electronic components.

Somedody had or have the same issue?

Thank you!!!

High performance FunToDo Industrial blend red.
I used 0.05 mm layers @12s normal exposure, 35s base exposure, 5 layers.

Have to love that stuff, was about to tinker with object scaling or even LCD resolution for the anycubic white.
Now I have my first nested cube fitting out of the FTD IB resin :)
Also printed some PCB casing, buttons fit perfectly, not on the AC white casing.

The object feel is very nice, they definitely have added some flex part. You get kind of a soft touch surface, smooth but feels a very little bit rubbery, I like it. Compared to other resin parts which feel like blank plastics from the press.

Sorry for dark images.
Still working on my cleaning skills, some residues got into after curing.

Hi Everyone, it's me again, since my last post got a lot of success, here is a quick guide on how to Increase Photon's led power to 40W.
First off, get the bottom unscrewed and disconnect lcd and fan. Then locate the green pcb where the Led wires are attached. Then you need to unsolder both sides, keep in mind the orientation and wire location, if you can get a picture of the board before, then get your new resistor and desolder the old ones, and replace it with the new one, CSRN2512FKR200 is the part number but any resistor with same specs will do the job, see the picture for reference. If you want to make something more, there is a schottky diode just under the aluminium cap, the black square with 2 legs on the bottom right, place another schottky diode on top of it and solder it to the bottom one, this would help the diode to carry more current SS54 is the part number, this step is not needed but will help the module to run cooler.
Put everything back where it was and job done!
But wait there's more, i've started thinking to put up something like a kit that has a wide led array like https://www.fepshop.com/…/paraled-upgrade-kit-for-phrozen-…/ for everyone to install in their printers. But i need first to check if there is interest. Keep in mind that the price for something like that could very easily get over 100$.

Two weeks on and I am loving this printer (apart from the resin costs) for the last 5 days it has been printing solid making components for a new FDM printer I am modding. I have printed hinges, door handles, smoother pcb boxes etc. Without tempting fate it has worked faultlessly and I haven't experienced any sticking issues since taking the advice from this page and its helpful members. Am still getting brown tinted clear resin after curing but it looks quite nice :-)

Testing pre-sensitized sceens for Silkscreening, part of the Photon 2 PCB and GFX project at Photonsters

First test was done with a 6-60 exposure and even tho there was images in there it all washed off. so I did a 60-600 exposure and then i got good results. So silkscreen exposure is possíble in the photon, and so will be PCB or metal etching

Best exposure time is around 7 minutes.

This goes not just the PCB makers out there but also to the modelmakers that want to do photoetching ;)

Photon can do PCB's. Now can someone validate photoetching... I have too many projects in my hands atm ;)
