    LW-PLA for buoyancy?

    I've had really good results with PLA Gloop for gluing and sealing printed parts. It is specially made just for PLA. Worth a try. Its easier than fooling around with epoxy and warping your parts as it cures (had that happen once). I have heard that 2 light coats of spray Polyurethane works, but...

    LW-PLA for buoyancy?

    You absolutely can do single wall prints. Vase mode in Prusaslicer is a great example. 2-3 walls is the default setting for a 0.4 nozzle on various slicers, resulting in a wall thickness of about 1.2mm(depending on layer height setting). Personally, I am a 10 wall guy resulting in 4-4.5mm thick...

    LW-PLA for buoyancy?

    This particular filament expands when printed which is why the flow rate is around 50%. Its intended to print single walled parts with designed infill bracing which makes extremely light parts. There are some great videos on Youtube for using it. Its not for any load or stress.

    LW-PLA for buoyancy?

    Less weight in the part would add buoyancy in relation to the water the part is displacing. Making parts or a float out of this filament would add a minimal amount of added buoyancy with less stability in the part. I agree about PLA, people have this vision of it instantly dissolving in...

    Filament Choice

    If you have a hobby or local store that sells filament, look for their sales on "ugly color" PLA. I picked up some bright red and deep purple 1kg PLA spools for $10 each on clearance.

    LW-PLA for buoyancy?

    I don't think you would gain anything from this filament. What little you would gain in less weight, you would lose in stability of the part. Its perfect for RC Aircraft though.

    Filament Choice

    It really depends what you are making. There are many different hybrid filaments out there now. I use PLA+ which, depending on the company, is a mix of PLA and ABS or PET that stands up pretty well to UV and the elements. I have some PLA Plus parts I made for my picnic table and boat that have...

    If you have (or anyone has) an oval cuff I could design one if you send me some dimensions.

    I am familiar with their systems. I did this not from a lack of product on the market, but rather "because I could".

    Sci-Tech has ovals. https://www.sitech.se/products/modular-solutions/qcs-oval.aspx

    I would think forcing the round cuff to oval wouldn't seal right due to the distortion.

    Wouldn't be hard to design. Do you have Ovals on your suit?

    Been wanting to do this for awhile, finally got around to it. Dry Gloves for my Si-Tech Quick Cuff System. Its up on Printables and Thingiverse if you are interested. These prototypes work suprisingly well for PLA+. I plan to do them in my favorite Nylon Carbon Fiber for durability. My first...

    I would think the Smooth-Sil 960 would work for casting.

    I use a 32GB card. works great.

    No lag! Make sure you are running a Class 10, U3, V30, A1 micro sd card. That makes a huge difference. When I first set up my Pi 3B+ I noticed some camera lag, stuttering and timeouts. Once I switched to the better card it cured that. The camera resolution is better too. The right card makes...

    OctoPi mods and lighting...

    Price for one. you can get them for $15. Number two, the B+ is overkill for running OctoPi. The Zero W 2 is perfect size and power. I switched so I could use my B+ for another project (media center). There is a shortage of Pi 3's and 4's and the price is outrageous if you can find one, so the...

    OctoPi mods and lighting...

    I know this is an old thread, but the new (came out a year ago) Raspberry Pi Zero 2 W handles OctoPi in a very small package. I got one last November from MicroCenter for $15 and replaced my Pi 3 Model B+. Anyone looking to use any Raspberry Pi's for any project I highly recommend a Class 10...

    Flexible PLA Plus

    Well, it came. I did a quick print test last night to get a baseline to establish settings for temp, speeds and feeds. I started with regular PLA print settings, 205 on the nozzle, 20% fan speed, no heat on the bed. I did back down the print speed to 50 as recommended. I use glue stick for bed...
