Hi from Boyds MD

[Max]

The Rostock Max V2 was just delivered today. Looking forward to getting it all together, and running. Surprising the slowest shipping got here in 2 days.

Oddly I'm probably more interested in the different kinds of filament materials that can be used, more than anything else. At least right now. I've ordered the PLA, ABS, Bridge, and a Wood composite. There's ABS with 10% chopped carbon fiber that seems to provide better strength and rigidity. It will be interesting to see how well the carbon fiber works with a different base material.

I guess the question for everyone is... If the glue stick works so great, why not just use a dual extruder, with one being a glue stick?

I've looked at a lot of assembled, and kit printers, and this Rostock came across as the best price for structural rigidity, speed/performance, build volume, and material capabilities. With that said I think it's more experimental than the MakerBots which seem to pull back on material capabilities in order to increase the quality, and reduce failure rates.

Thanks,

-Max

Only a small amount of glue stick is spread on the glass plate to help adhesion, certainly not enough to dedicate an extruder to it.
Have fun building your Max V2 and we are here if you have any questions.

Hey there! Welcome!

The build is going very well considering I'm only getting an few hours here and there. Only 60 pages left in the build.

I do have one pair of eyes on the cheapskates that had to look to the left because I flipped the back plate.

Has anyone used thermal compounds (non-electrical) instead of the RTV? Just wondering if it's better to have more thermal conductivity. The Kapton tape on the outside of the Onyx plate, you could put a small pool of thermal paste, and then tape down the thermistor, and paste on the back. You could still add the RTV to seal it in if you wanted.

Of course I haven't figured out the thermal drift between the heat source and the sensor yet. It might not be enough to matter.

The docs are pretty good. Only a few places I would have taken a different picture, but the text covered the details I needed to know.

Thanks,

Build done. No missing parts, and just a few extra ones.

Got the expected rows of blocks on power up, and no smoke. LOL. Now for the software side, and calibration.

Great job on the Kit!

Discovered that I need to update the prescription on my glasses when doing the soldering.

Thanks,

congrats! I hope to see you posting about the materials you experiment with. I've been printing for about 3 weeks now and after brief experimentation with ABS (because the first thing you need is a fan shroud) I have stuck with PLA because it doesn't warp. but lots of my ideas will require abs or stronger materials.

One topic that seems surprisingly unreasearched is printing hollow objects with gcode pauses built in that would allow you to fill the print with cheap, quick fill. hot glue gun has been suggested, but this seems pricy and difficult.

I got to see the SeeMeCNC gang at the Science/Engineering Expo in DC. If you ever get a chance to say hi in person, I suggest you do. Good people there. It was an awesome expo, with a ton of interactive exhibits for kids.

My Flexible TPE came in today. Looking to use it to make molds, and maybe a pair of Back to the Future sneakers. LOL.

I just got a new thermistor for my Rostock, so I still have to calibrate it. But I have plans for playing around with the following.

1. ABS
2. PLA
3. Taulman Bridge
4. Zen Toolworks Wood
5. NinjaFlex TPE Flexible

The infill is an interesting area. I'm seriously looking at a filament extruder to try 3M's glass balloons. They make some that are in the 0.1 mm and small range. But I don't know if they would survive the mixing and creation of the filament. But they could provide a lighter infill with less material, and more strength then with Slicer based infill. But you're still looking at 2 extruders.

For the materials that warp. I haven't looked into this yet, but wouldn't having an insulated housing around the printer handle that. The part doesn't cool at different rates until the print is done.

There's a kickstarter project for a 10% chopped carbon fiber embedded PLA filament. The number are interesting. https://www.kickstarter.com/projects/13 ... 3d-printer

I see over the next few years, 3D prosumer printers supporting at least 3 extruders. 1. base material, 2. infill material, 3. support material.
