Hi, where i can buy the Siraya Blu Resin in Germany?

FunToDo Castable first time Investment casting. I did some oilsand castings before, but casting pistons is a nightmare every time because you have to build serval moulds for the cores. Investment casting seems to be a lot easier with the Photon.

Plaster mix: 1/3 Playsand - 2/3 Modelplaster
with 1/3 Water mixed by Volume.

The first Print with FunToDo Castable failed, the Chitubox supports were too small(i used standard heavy). The second print with Robert Silvers Netfabb medium support script print like a charm. @ 16s/Layer without warping.

The mould is in the kiln at the moment. I will try the slow burnout cycle suggested on the resins website.

The piston is for a small 2 Stroke engine I build. It will be cast with an AlSi alloy and I have to do some machining after casting.

I'm curious if that works. Any suggestions?

I did some testprints at various temperatures with Photocentric High Tensile Grey.
After a long overnight print, the screen/resin temp was at 40C with 35s exposure.

Then i did some tests.

First i did a print at roomtemperature 20C and a second after heating the printbed and Vat slightly to 40C with a heatgun.

Printed with 10s per coulum.

We see a lot better Print at 40C with a sweetspot at 60s. The exposure at 100s20C isnt as good.

Temperature matters. I will do further tests with Anycubic resin

Sorry, my phone can not take better photos.

Hello, i really like the material properties of the Photocentric stuff, but the cure time for the Tensile UV DLP is very High, more than 60s per layer according to the resin xp finder method to reach very fine detail. 24s for basic detail that the print works.

I have a 50W 405nm LED from a past project laying around.
-What would happen if i build in this LED with a proper powersupply and maybe a SSD relay in my Photon?
-Did anybody modified the LED ?
-will the LCD handle the double power?
-Are cure times linear with LED power?
Thanks
