Really looking forward to seeing the results!

Having received the full scale Terminator Endoskeleton now, I will start buying stuff to begin production back up. I'll start with some more resin as well as a Wash and Cure station and then I'll find a place where I can get the Phrozen Sonic Mini 8K printer - will probably upgrade it to a DLP printer once they've reached the 8K market, as it is a better technology. I hope it won't take long, but please be patient while I get things sorted.

I'll keep you all updated along the way.

Wash and Cure station and more Water Washable resin has been shipped. Will probably be able to pick it up on Thursday. Going to find the best place to order the Sonic Mini 8K from soon. Hopefully I'll have things up and running soon after that.

I just learned yesterday that the printer I was planning on getting has a slightly larger cousin in 8K that gets released about the same time - the Sonic Mighty 8K. It will be released early July, so when I get it I will do tests people suggest to dial in the best layer burn time to achieve the best and sharpest results. Hopefully if all goes well, things will be slowly up at running sometime during or near the end of July. Sorry for the long wait, though this gives me time to prepare everything before I get it, so at least there's something good coming from the delay.

Just pulled the trigger on a Phrozen Sonic Mini 8K, as the shop I'm buying from will receive a small batch tomorrow, with the notice that the Mighty 8K has been delayed until August at the earliest.

I'll keep everyone posted.

First test print on the new printer was a success but it was a failure in the sense that it adhered so hard to the print plate that I had to destroy the print in order to get it off. And I used their optimal settings on their website. I will now have to figure out how to go forward as I do NOT have the strength or stamina to battle with such shit and even less desire to see the print destroyed because the adhesion is too extreme.

What to do... what to do?

Been watching some more 3D printing videos and some explained how I could fix the issue I was having with the prints adhering to the print plate too hard, so I'll try and get things moving so I can dial in the printer and get these prints started.

Am still hit with a lot of health issues, so things are moving at a snails pace these days.

I'll keep everyone posted on that. Note: Did get sick again after I posted this above message on another forum, so things are taking a while to get started, but with the new info I'm hopeful I can get this working better now.

On a different matter. Anyone who knows me knows that I love 3D scanning. Even when it goes wrong, because you see the object slowly form in the scan viewer and it's like magic to me. To be able to recreate something just by pointing a 3D scanner at it and then having a digital object in the end that is a near perfect representation of the original - depending on the scanner - is just amazing.

So when I saw this when browsing through youtube lately I was happy to see this is finally happening. I had long gone with the idea of replicating stormtrooper armor to go with the helmets I have in this project, but seeing as this project has taken so long and is still struggling it is cool to see someone else get it done.

RS Prop Masters 3D scanning their stormtrooper armor for scaled replication:

Here's to me hoping they'll do 1:6 scale versions as well.

Test calibration prints prepared. Hope with the new knowledge this will go better than last time where I demolished the print in order to get it off the print plate... and lost all energy for the rest of the day.

Man... I really wish I can dial this in so it will become the glorious experience I see everybody else have with resin 3D printing.

First test print was much easier to pry off, but I broke it in the process. I tried with bottom burn time of 10 seconds. Now I lowered it to 9.

Got it off in almost 1 piece. Some corners did snap off. I may keep it at 8 when I do my regular printing, as I don't care about not damaging supports - would rather risk damage to those than the print peeling off the print plate during printing. Will try a bottom layer burn time of 7 for the next one.

Normal layer burn time looked pretty good, but will try a 2.6 seconds burn time for the next one to see how it looks.

I'm getting close.

These calibrations may not work for others. I'm dialing it in for some water washable resin.

2.6 seconds normal burn time was too low. So it seems my settings are 7 second bottom layer burn time (or 8 to be sure) and 2.8 seconds normal layer burn time. Testing these settings on an ESB chest box.

Dialed in the settings to 7 seconds bottom burn time (or 8 to be sure), and 2,8 seconds normal layer burn time to get the best result.

Printed an ESB Vader chest box as a test at 0.05mm layer height and it turned out really well. I used that layer height to save time for the test, but I can go down to 0.02mm when I really start printing. I printed it at a 50° angle, but may just print it laying flat as it may give the best result.

Sorry for the fussy picture... I couldn't get a sharp image as I can't hold my hands steady enough for it to keep the focus. The white specs are simply because I didn't clean it properly before curing.

Tested out some settings when printing a RotJ chest box. I reworked the box from how it previously looked, as I received some better reference and pretty much every part was worked on to make it more accurate. It's not 100%, but it's much better than before.

The below picture shows the difference between the 0.05mm layer height less than 2 hour print vs the 0.02mm layer height 5 and a half hour print.

I'll let you be the judge. Do you feel the extra time and slightly sharper detail is worth it? I know how I feel after seeing the comparison.

Doing some more tests with the 0.05mm setting. Dennys Wang on Youtube suggests anti-aliasing to get rid of voxel lines, so I'm testing 2 types of that - one sharp and one blurred, as Dennys Wang suggests the latter with anti-aliasing 2, blur 2, but he's using another slicer than me, as Lychee doesn't have the exact same kinds of settings. I may try it in Chitubox with his exact recommendations later to see if I can get even better results.
