Additive build (3d printing) vs subtractive (CNC mill) and were to start...

I thought this might be useful to the subset of boat builders who also have 3d printers:

Here's your farm machine, Jaysen.

If it runs like a typical Prusa, it's going to be hard to beat.

Yeah. I've been looking at prussa and the folks that are using them as core to other scalable products. I'm running into a small problem though... https://flex3drive.com. The "multi-material" capabilities with full embedding are ... tuff to ignore. Think dropping a petg flex arm between two blocks with no fasteners and zero clearance. Now think about electrical connections and conductive materials. Suddenly I can build crap that needs very little assembly.

Also can print 3mm line with 1.75mm booger string. Which makes all my tubes "spirals" and 2hr prints.

I haven't pulled the trigger on this yet, and I may just use it on one customer printer with a couple vorons (still lusting for those) as my workhorses. I need to get away from these tubes though. taking up all my print time.

The new Voron Trident "Beta" (the Voron 2.4 is "Frost"... Somebody here may get the reference). Bought the kit for this a year ago but have not had time to get it built until recently. I still have some tweaking to do, but she seems to run pretty well.

One observation of the new machine, is that while the toolheads and X-Y motion system are basically the same, the kit for the Trident came with the "high flow" version of the the Revo hot end, which wasn't available yet when I bought the 2.4 stuff. I have the parts to convert the 2.4 to high flow, but I won't install it until after I get the Trident dialed. Conversely, the 2.4 is running input shaping, which is a resonance compensation that allows for higher travel speeds without reducing print quality. That requires a calibration procedure using an accelerometer on the toolhead, and I have other configuration work to do on the Trident before I get to that.

The upshot of that, is that while the 2.4 can currently hit faster travel speeds than the Trident, it's flow limited to the point where the Trident actually prints faster, as long as I am using a 0.6mm nozzle. With the smaller 0.4mm nozzle for better detail, the 2.4 still has an edge. Looking forward to when I can get them both going at full speed with the HF nozzles.

I’m printing with 1.0 80% of the rim right now. My poor ender 3 still manages to runs about 50mm/s at 200C on the hot end. The problem is just getting the booger string hot enough, on its way through. From what I can tell, even the Vorons will suffer the big noz slow down that happens at 0.8.

I’m still in negotiations with the bank on getting a second printer. I’m close to adequate work to justify it. Just need to get the blessing …

[Netpackrat]

Well, turns out I was wrong about the Trident being faster with the bigger HF nozzle anyway, it had just seemed like it was screaming along. But the 24 still has a bit of an edge. Lots of artifacts on the print at those speeds without input shaping running as well.

If you are going to take me up on the offer of the Voron parts, let me know so I can get started on them. I don't like letting my printers run when I am not around to check up on them, so it will take longer that it otherwise might for that reason. Anyway while I was typing this, I got the word that my pallet-o-aluminum for the Specmar landing craft arrived in Anchorage, so I'll be picking that up today. Glad I got the Trident together when I did.
