    Re: 3D printers


    If all you are printing is basic little things that you could consider (hobby grade) then a hobby type printer is fine. I use an Ender 3 Pro for little hobby type items and it works fine for what it is, a cheap printer. I am not building automotive prototype parts or anything, just little random shit. It's a $200 printer that is great to learn and play with.

    Looks like just under $20/kg.


    Makerspaces are effing cool. But I don't share well. Also the time constraints are a thing. Many of these designs take many hours to print. How the hell do you timeshare a machine with others when it takes that long?!
    Yep, for most stuff PLA is perfectly fine, and it's fucking corn starch.

    The most useful thing I've printed was an adapter for the MIG welder, so it can use 10lb spools of wire. I can't take a picture of it. It's in the welder.

    Most other stuff that I print has been trinkets of some sort. Team logos, a watch stand, story point dice. One of the guys at the makerspace has 3d printed himself and Ironman costume.

    Different makerspaces have different rules about this. In Manchester you start a print and perhaps post something to slack. When someone stops by the space they take a picture of the current status and post it to let you know how it's doing. If something bad happens they'll generally stop the print and ping you to tell you it's effed up.

    We've had good luck with both the Hatchbox and the Amazon basics PLA. We've tried some of the cheaper ones, but every time we try we run into problems. The Amazon basics comes in a resealable bag to help keep moisture out, which is nice.

    What would one print on the $200 kit?
    I got curious on them but never pulled the trigger.

    Whatever you want.

    I designed and printed this for my best friends fiancee's birthday.

    Shared album - Christian Smutnick - Google Photos
    3D printers-img_20180502_155544-jpg

    That was a huge pain in the ass to get off the plate. Was about 9"x9"x3".

    I've also designed and printed fixtures for work to hold lathe parts while measuring with the vision system.

    Re: 3D printers

    I also tried printing replacement fins for jarts lawn darts but never got them to be strong enough to stand up to the task. The layers would always separate too easily. Might try to research other materials and try again this winter.

    3D printers-img_20180407_232003-jpg

    And the dimensions weren't right so I'm going to just design the whole thing on my own next time.

    $200 unit I mentioned has a printable space of 220mm x 220mm x 250mm... so about 8.5" x 8.5" by 9.5". Prints in PLA (the cornstarch) very well from what I've already seen. Supposedly does ABS and several other plastics as well. ABS is seriously durable stuff. Unless I'm mistaken, most motorcycle bodywork is made out of ABS.

    And then if you can figure out the CAD software (and the design aspect, which is definitely not trivial) you can make almost anything you can think of.

    I want about a hundred little helpers, guides, and knick-knacks for the wood-shop. Crap that I look at Rockler and say "cool, but no fucking way am I paying that much for that!"

    Remember $200 buys you the KIT. You then have to assemble, setup, calibrate and learn how to operate it. Plus feed it supplies. As said, looks like about $20/kg for the common material, more for exotic stuff. Supposedly you can print carbon fiber?!

    Does anyone not use slack?!

    Wish I were closer to Manch. That space looks pretty cool. Kid at work is involved in one in Nashua. He's done some fun stuff through them. Such a great idea.

    I need to be retired. Life would be easier without work wasting my days.

    Some printers are more assembled than others. The E12 you just had to connect cables while the A8 requires a few hours of assembly.

    And what's slack?

    There's always that one guy!

    Manchester is not in your natural path.
    There's Port City in Portsmouth and Lowell Makes, that might be better fits for you. I don't have any personal experience with either of them. There also seems to be something called Creatorpult in Haverhill, which I know nothing about. Lowell Makes has a solid reputation.

    Slack is a messaging platform. Big with tech type companies. Mostly focuses on near real time communication. They have a lot of integrations with other types of techie tools, so people can geek out about all the things they can make it do.

    I'd also be happy to schedule and intro to Fusion 360 class if there's interest from NESR. Class would be limited to 4 people (as that's how many machines we have in the lab).
    It's pretty basic, but gets you started in being able to explore different ways of solid modeling in Fusion.
    You'd need to create an Autodesk account in advance.
    Class lasts about 2 hours and price would be $30 per person.

    Re: 3D printers

    Turns out the wife is as big a geek as I am. She had a Ender 3 printer on order to be tucked under the tree before I even tickled this post.
    Plan on dialing it in and giving it a whirl later today. I have 1kg of PLA ready to feed it. Orange. Of course.

    Got half way through this Fusion intro. Much to learn.

    Re: 3D printers

    Slack. Printer is hooked to an octopi (raspberry pi running octoprint) and then posting periodic status & alerts to a slack org my wife and I use.

    Need to get a camera hooked up to it for those epic octolapse time-lapses..

    ..all this and I haven't even learned how to slice yet. Can't get the bed leveling test print to print clean.

    I found the test prints they had loaded printed like ass. Once I sliced my own they printed better.

    It's a cable clip... for the machine that printed it.

    That is one huge raft you used for that print.

    Re: 3D printers

    That's the "recommended" settings sliced using Cura and it still took 4 tries to get that to stick.
    I've since printed a couple more without the raft. It seems to finally be sticking better now.
    Also finally figured out how to print more than one part at a time.

    I gotta find a cool toy to print for the kiddo..

    The bed is some sort of magnetic backed plastic. It kind of sucks.
    I'll fit some glass at some point.

    Re: 3D printers

    Do yourself a favor, take that magnetic bed off and buy a glass one. Best upgrade I put on my ender so far, prints stick to it so much better! And a little tech tip, if you still have issues with prints sticking to the bed use hair spray on the bed.

    Re: 3D printers

    I started with hair-spray. Wife doesn't use it. Found an old bottle in the back of a closet somewhere.. but it seemed to help.
    I think the bed is more broken in now as it seems to be sticking better now. I'm wiping it down with isopropyl between prints.

    People on the FB user groups are saying the same thing; go to a glass top. I think I will before long.

    Right now I feel this strange urge to keep the machine printing 24x7. Going to need more filament. A lot more.
