3D Printing Projects - Truck parts and tools

That blows. Too bad ideas need to be held close to the chest and then some when it's a badass idea like yours @kennyw
 
I watched a few vids about CF getting microscopic fibers all over the place and also how the printed parts are sometimes weaker than a comparable non-CF filament. I'll pass on that with my open printer sitting right next to my desk. Seems like an enclosed printer and better filaments like PC are the better option.
 
Welcome to the world of manufacturing new ideas. The abuse and copying is absolutely rampant. Rest assured her copy will be copied until its a 6th generation copy and mass marketed everywhere under the sun in the blink of an eye. You'll start seeing ads for the item in the next few weeks.


As far as CF filament, I have never had a problem during printing. It's the grinding where you should be using a respirator. I've been grinding CF for nearly 2 decades and I'm still kicking, but the respirator is key. I've got printed PET-CF parts in my rig for a few years and they hold up pretty good.
 
I would recommend an enclosed printer with HEPA filter and activated carbon fibers to reduce exposure to VOCs and micro particles of plastic and CF/GF when used.

I'm aware of the abuse, really the main reason I'm not interested in selling my parts commercially and gave out the design for the DIY community, in part to see how well it could work, or not.

I ordered PETG-CF, PAHT-CF, PPA-CF, and PPS-CF.

Figured they all had different applications, and I would try them.

But I am a little concerned, I also think even with the carbon/HEPA filter I will need an exhaust outside or something to be safe with anything but PETG or PLA.

That's why I print in the garage. Away from the indoors and humans.

Go through the Bambu labs online academy. They cover some basic limitations of the filament types as well as applications. There are also DIY filtration systems you can print parts for to either connect your exhaust fan to an external vent, or increase filtration to safe levels.

Where do you buy these materials at are they expensive?

There are many sources. Amazon, Bambu Labs, and about 1000 others. Bambu doesn't make their own filament, but they either buy in volume on a spec or repackage other vendors filament. But they have features in their filament like RFID tags so the AMS automatically recognizes what the filament is, and sets the printer parameters to match automatically based on extensive testing done by Bambu Labs for good results with little fuss by the user. They also conveniently provide parameter sets for other common printer filament that you can manually assign them and get good results.

Yes I ordered the Voxel HEPA filter setup, should arrive tomorrow. I originally thought that was enough, but I do wonder, especially with kids. I will probably create an exhaust pipe outside somehow to be safe when I run the higher temp materials. I'll review the Bambu safety protocols.

How long does a spool last? Sorry for all the noob questions.

Each spool is 1 kg, so over 2 lbs, which is enough to print quite a bit of things depending on how big they are. The kids have been printing quite a bit of stuff, and we are still on the dame spool after the machine has been ran for over 30 hours thus far.

Some spools during the bambu sale were as cheap as $12 a spool, and some are very expensive, the normal price of PPA-CF is $150 a spool. I bought some while it was on sale for as much as 40% off, but the sale is mostly over, for now.

Really depends on size, infill, and amount of supports. The slicing programs will tell you how many grams of filament each print will take. The little fidget spinners and articulating toys you see are 50-150g. Suffice to say that you'll get more than a dozen prints out of a single spool. It's pennies to print stuff.
 
I expect to get about 2 sets of these cup holders out of a 1kg roll of filament with a little left over for the badges. I have started weighing my rolls before starting prints to verify if I have enough filament to finish the job too. I managed to run out of one of the starter rolls on a test print just as it was finishing the print with only a couple grams of filament left in the tubing at the end.
