My first model I’ve printed on the Titan 1, aside from the calibration test model that was recommended to me to try out first. Doing the calibration model really helped me understand the differences of how the resin and exposure times work.
So, on to my prints. I did a smaller test print of the whale before I did the larger version. All supports where made by hand in a 3D modeling program called Silo3D. I’ve discovered on larger prints, I really should have connected the supports more, as the model shifted considerably, especially on the long fins on the larger print. All in all though, I am really impressed by this printer! I have and FDM printer that is pretty nice, but the quality is way higher with the Titan 1.
Spot HT Resin
Whale mini: 4 inches Tall
Whale large: 8 Inches Tall
95 micron xy, 50 micron z
Print time Whale Mini: 22 hours
Print time Whale large: 45 hours
Exposure settings generally where around 29 seconds for most of the print. More for the lower support layers. Lift speed was set to 15 for the first 200 layers or so, but I increased it to 50 for the rest of the model. Kudo3D support said to not do that, as it will lower the vat life so I’ll keep to 15 for lift speed from now on.
Initial observations are that the Spot HT resin pics up detail well. But it’s also hard to remove the supports without causing pot marks. Filled most of them with Milliput, but I’d like to see if I can do better on support removal on my next prints. Also found that the anti-aliasing setting is needed, as the layer lines really stand out at the 100xy micron range IMO. I did the Whale mini with no antialiasing, and you can see some stepping throughout the whole model. But the larger one there’s only a few parts that showed it, but they were easily sanded away.
Looking forward to doing more with this printer. It’s light years easier to set up than FDM printers, and the way it handles overhangs is so much nicer. Should have looked into one of these much sooner!
