350 Trident self source questions

[sbman]

I've decided to build a Trident at it's max size of 350mm. Doing it self source and fabbing as much as I reasonably can because I enjoy that sort of thing. I've built CNC machines before this is just the first 3D printer I've done.

The plan is to keep it mostly stock, but with a USB toolhead, umbilical and an Eddy bed sensor.

• Stealthburner toolhead w/Mosquito hotend
• Nitehawk USB toolhead board

I've been looking for the specs for the 350mm sized parts but am not finding anything.

The fusion and step files are for a 250. Is upsizing it as simple as adding 100mm to the parts that would need to scale or is there a source I am missing for a version of the model at 350?

Making parts like the top plate will need a fair bit of drawing modifications if I need to add length to the areas that expand but keep cutouts and slots the right size, it would not be as simple as scaling it up 1.4 times. I've got a large format laser cutter to use for cutting panels and such, but will need drawings that fit the machine size I am building.

I'd advice you against the Mosquito hotend, as it isn't supported by the VORON dev team (it's too wide, which interferes with proper part cooling).

You can use the configurator on the site to check the dimensions of the extrusions. Keep in mind that the stock Trident does not scale on the Z axis, only on the X and Y axes. If you want to have a higher printer you'll need to either find a stepper motor with embedded leadscrew that is long enough for the desired height and is not bent, or install a belted bed mod.

Since this is your first 3D printer, from where do you intend to obtain the printed parts?

For the printed parts, I may know someone at work that can print ABS, or I'll look into PIF.

I've got an Elegoo Neptune 4 Pro but trying to do ABS on it would be a stretch.

I did run the configurator and saw the length of the extrusions there for a 350 size. That doesn't help much with making cut files for things like the bottom plate and STLs for the decorative pieces. Are there STLs for the bottom trim pieces at 350mm? The bottom plate should be fairly easy to modify for the larger size.

If you can get the Neptune enclosed you should be able to print ABS. I printed up my Trident 250 on my Prusa Mini+; I kept the shipping box and put that over it. The only parts I had any problem with was the feet since they are bigger chunks of plastic; adding a big brim resolved that and they are still on the printer to this day. So if you can find a big enough box you are set; I've even read about people putting their old Creality printers under trash bags to get the ABS parts printed. As long as you can prevent drafts and make a warm bubble of air around the part you should be good.

For the printed parts, the only ones that care about the size are the skirts, and the Trident 350 parts are found here: https://github.com/VoronDesign/Voron-Trident/tree/main/STLs/Skirt/350

What hotend do you recommend? From the research I've done since you posted this, I am kind of thinking the Stealthburner toolhead isn't necessarily for me. I want to be able to print both PLA and ABS effectively and from what I've read it looks like the Stealthburner doesn't have adequate part cooling for PLA. Am I on the right track there? Would a Dragonburner be more flexible with materials or do I just need to choose a tradeoff between filaments that require a lot of cooling vs ones that don't require as much?

It all depends on your intended use case. The Stealthburner, as all the previous toolheads of VORON printers, was designed to print ABS well, and that it does. If you want to print PLA as well one toolhead that people have been talking a lot these days is the A4T. If I dare make a suggestion, for printing PLA on a Trident I'd prefer adding these auxiliary fans and keep the Stealthburner, but that's me.

That makes sense. I think I'll start with the stealthburner and see how it does. Once I start printing abs I may not want pla much anymore. Just have to pick a hotend for it.

For ABS you want an all-metal hotend, most of them are these days. I still use the good-old Dragon hotend, I don't print blazingly fast so it's Good Enough™ for me.

Stealthburner can print PLA just fine. My 3 (4?) year old Trident is still running Stealthburner with a Revo hotend and it's printed spools and spools of PLA. It's got about 4400 hours on it (shocked both Steve and Maks with that ) and over half of it is PLA. I also don't run super fast, I prefer good parts over #speedboatraces.

 

[sbman]

I prefer good parts over speed as well. It seems like anything I use will perform at least as well as the printer I have now.

The dragon hotend looks like a great option I like the V6 compatible nozzles, non structural heatbreak, one handed nozzle changes, and copper heatsink. This would be my preferred hotend from the available supported choices.

Problem is I can't find one to buy. All I can find are random parts here and there, no complete units anywhere except sketchy ebay listings.

It looks like the "Phaetus neXt G Extreme Gradient Drop Effect" is the current model of 'Dragon'? https://www.phaetus.com/en-us/products/next-g-hotend
Phaetus claims the same footprint as Dragon and I see it available to buy various places.
Does this sound correct?
