Discussion in '3D printers' started by Jose A. Molina, Jun 9, 2016.

The Roberta Clementine a proof of concept and progenitor to the series of printers I will be calling the Clementine Sisters. The printer is named after Pittsburgh Pirates baseball player Roberto Clemente. Although it is more accurate to say the printer is named after the school I work for which is named after Clemente the Roberto Clemente Charter School. http://www.myrccs.com Roberta is the first and not really built to last but instead built to test ideas and to produce the parts for successors

3D Printer made of wood

    must be the cheapest 3d printer I've ever seen.
    I like how you used anything you could get your hands on, to build parts.
    The thought of using a DIN rail for precision would scare the hell out of me but hey, if it works, it works.
    Good luck, Jose.

    Lol thanks. Low cost is my mantra. The DIN rail worked fine for a bit. then the grooved bearings wore out. i actually replaced the metal electrical plate with a block of wood that i shaped using a bandsaw. basically by hand. some lithium grease and it actually made a super smooth rail. but i did eventually convert to hardened rod and lm8uu bearings. i don't like them but they havent worn out yet. The whole thing is a test bench for learning and motivating students. i think wood is more approachable then aluminum. but i've gotten openrail to play with now so Alice Clementine will be more durable.

    you can see the wooden rail in the attached picture

    must say, it's a flinstone version of a 3d printer, and it works.
    I would be scared to use such parts for a precision machine, the mechanical engineer in me would scream and shout.

    why don't you keep the old wooden clementine, and build another aluminum one afresh?
    this way, you can always look back at the beginnings.

    Definitely. Alice is a stand alone daughter. i've made several mistakes so far on the aluminum but i haven't got anything post worthy yet. I've definitely considered keeping Roberta a presentation/teaching model. I've already found and bought better motors for Alice, and Roberta has a mascot vibe i think works to get the kids interested.

    Thanks. we're heading into summer so things get a little weird for us support staff. We don't get the summer off like teachers. but i have a lot of vacation days coming to get tinkering.

    Right. There's always a way. I think we need to teach that failing forward as many times as it takes gets you to your goal also.

    I am truly amazed that you made it work. Great job! If there is something specific you need in the future to help with your club,. let me know, If I can help, I will.

    It was a great learning experience. and Roberta is a great teaching tool. now im working with my kids to get some projects show worthy so we can start fundraising for commercial printers. theres just not enough time in the day to keep fixing roberta while also teaching. lol

    You sir are my new personal hero. :D
    I love the concept here and the adventurous (if not downright fearless) style of engineering: build it, break it, improve it. I tend to get so caught up in endless research and designing that I never get around to actually making something. I've been wanting to make a 3D printer for ages, but the first step in most builds is to 3D print the parts. I call it The Maker's Paradox - to make it you must first have it. o_O
    Your build totally circumvents the Paradox and I am SO making one of these! (after endless hours of designing first, of course...)

    Sometimes you just have to start. Hell or high water. I do get stuck all the time too. The way myhead works if i can zig zag around and obstacle I'll do that but if i get stuck I'll sometimes just walk away for bit too. I have a daunting number of halfway finished projects. The key is to have fun. If it's not fun then move on. Mercifully I can say that cause it's not my day job.
