A Year of 3D Printing

Re: A Year of 3D Printing
#62I would encourage people who have never designed physical objects before to try to only print things they have designed themselves as an exercise. For perhaps a year or so. If you have never designed physical objects before it is really challenging at first. The learning curve is pretty steep and, at least in my case, I discovered that I didn't have a mental language for thinking about functional 3D and mechanical de…
I don't do this because I don't have the time to design wargaming terrain, but I've definitely pushed myself to do more designing for household things.
It's a really good feeling to be able to put something together that solves your problem. As I asked my wife, "Is this why people with wood shops are always so smug?"
It's also fun to be able to feel your skills building. I now have opinions on friction fit box lids.

#63One of the most useful things that I print is Gridfinity storage boxes and holders. I try to organize as many of my tools and supplies using it. I sometimes do a little leather working for fun and have a drawer full of hardware, all in their own bins. In my garage my sockets, wrenches, etc. all has a Gridfinity holder. I design my own as much as I use pre-made ones. A while ago I even saw a shop that used it to organ…
Any reason you are recommending PLA instead of PETG?
For some applications, PLA is a little more rigid. It will then fail in a spectacular fashion, but "I need you not to bend" is something PETG doesn't always perform the best for.

#64Earlier quoted context omitted.
any reason to use PETG instead of PLA? PLA is plant based, in theory bio-degradable, while PETG is produced from crude oil.
Less creep, slightly better at absorbing shocks without breaking, better failure behaviour (PLA can suddenly shatter leaving sharp edges, PETG tends to deform elastically first).
Note that "deform elastically" is not necessarily a desirable failure state if it happens earlier than shattering.

The A1 has a relatively small printing plate. How does it work for boxes that are larger ? You print them in pieces and click / glue them together ?
I print wargaming terrain that's bigger than the bed of my P1S from time to time. The clear Gorilla polyurethane glue has worked really well for me.
Re: A Year of 3D Printing
#66All of this was on a Bambu A1 Mini? These are the types of things I want to print. My Ender 3 was so finicky, I only got a few out before I gave up.
I just got a Bambu P1S (they are / were on sale since the P2S came out) and the difference to my Ender 3 is truly night and day. I almost never used the Ender, since it always resulted endless tinkering and even then, the prints never came out well. The Bambu worked flawlessly out of the box.
The P1S is such a good printer.

From my experience PLA is just easier to print - prints are less likely to fail and more consistent.
Also due to lower nozzle and bed temperatures, prints start faster so you can check the first layer sooner before you let the printer do its thing.

3D printing has been humbling for me.
I can express myself well spatially in code, but that doesn't help much in CAD where you have to figure out what combination of buttons and parameters will do what I want.
I can manage dependencies well in code, but that doesn't help much in CAD. I continually struggle to design parts with geometry that is dependent on the spatial relationships and constraints of how multiple parts connect together.
Re: A Year of 3D Printing
#70I still have mixed emotions about 3D printing. I do love the idea of being able to print a part when I need it for something. But I do hate myself at the same time for creating more plastic junk. PLA is not really getting recycled, when it fails someone throws it in the trash and it goes to a landfill. Maybe some really diehard enthusiasts are ensuring all their failed prints and broken parts get properly chemically…
if you printed what you NEED, how is that junk?
