Re: getting a 3d printer...


Oh man... I finally came to terms with a Lack cabinet not being suitable for my needs, and now you drop the idea of a kitchen cabinet base. Drawers. That would be awesome!

Sometimes it comes down to myriad personal backgrounds/experiences. (Age may also be a factor, but let's not go there... 😉 )


I have this very heavy metal table leg (intended as a single central leg for a 150cm diameter round marble table), which is really stable (RufusClupea: I may end up being glad I hoarded that one ;-)). I'm thinking of using it as a base: add a piece of kitchen countertop and then take it from there. It might not be the most functional as it lacks more storage, but it would put the printer very stable at table height.

Stability under a static load is one thing; stability under a dynamic load, i.e. a vibrating, moving (in three axes) and potentially top-heavy machine (depending on spool placement) is something else. And let us not forget harmonics. (I know your plans are to move the spool/s elsewhere, but once you get up & running, there's that initial urge to PRINT SOMETHING! 😀 ) I'd hate to hear it crashed (literally) on its first print! You could wind up having to add additional support anyway. Please check that out carefully before committing to it. Stability is one of the primary arguments favoring corexy machines over gantry designs.

Re: getting a 3d printer...

It's deeper certainly, but not particularly huge. My entire print station is a 28inx24in/71cmx61cm side table. That leaves room for the printer to be set back a bit from the front (to avoid dog-dozer), and the Y axis to be backed up completely with room for spools behind without being cramped.
Which one is the depth?

Dimensional nomenclature can vary, depending on discipline/industry--it can get confusing. I believe bobstro's dimensions are width x depth (front to back) x height. (BTICBW 😳 )
Turning the table 90° is possible, and with side tables often doesn't matter, depending on the design.

That's "MISTER Old Fart" to you!

True, but the harmonics is something I can only see when I will try. It is not really something I can plan for and have to starts somewhere. For sure I will not build anything before having the printer, as that is the only way to be sure on how some things vibrate, fit and fully know what is necessary. I can then easily test things before fully committing to the build. But now I plan to use the design of the rack/cabinet/enclosure/whatever as my test case to start 3D modelling again (my Autocad and 3D Studio Max skills are from a distant past). I found Fusion360, which is apparently what Bobstro also uses, and am giving that one a go. Also, being by Autodesk may make it similar in some conceptual aspects as that old software.

Well, I just needed a small amount of convincint that a Prusa would be the way to go (even though nearly every website comes to that conclusion); it is just this psychological aspect of "it looks simple enough, why would I have to pay twice to get something similar".
And from there it just went to all aspects related to getting a 3D printer: filament, colour prints, materials, modelling, accessories, naive comments on spools storage, insights in hobbyists and hoarding, pets, kitchen sink, ...

I've learned a lot and manage to put the things I find in perspective.

True, turning is an option but it may not be a convenient orientation for using it. Also, the device may fit on a 61cm deep table, but still protrude while in operation.

What is BTICBW?

Well, I approached it from the side when I measured and didn't think, but the front of the printer is aligned with the narrow side. It will depend on how the filament is laid out, but I do have it behind the printer, so need the 28 inch depth.

Positioning the filament stand will determine which dimension needs to be deeper. 61 cm will fit the printer, 71 cm will fit the printer and filament stand I'm using if positioned to the rear of the printer.

We are not that bad... Everything here helps me, because it is not only the aspect of getting the printer, but also taking care of things that come with it. After all: it is not *just* the printer; it is not like a regular printer that you just put somewhere and it works; I already know that I will need provide for some infrastructure and will need to get some other things.

Actually, this brings me to another question: any specific tools that are of interest (apart from the obvious ones)?

Is this the point where I say "Get off my lawn!"? 😀
I suspect the real kids use some modern style hieroglyphs now... 😕 But honestly, I've never seen this one... And google backs me up: only 2610 hits and none of the first 20 explain the abbreviation! More common (13000 hits on Google) apparently is BICBW, not that I would have know it either ;).


Positioning the filament stand will determine which dimension needs to be deeper. 61 cm will fit the printer, 71 cm will fit the printer and filament stand I'm using if positioned to the rear of the printer.

Thanks!

The kit comes with the tools necessary for building it. [EDIT]...Except a caliper. It's not required at all, but I bought one anyway, and was glad I had it. I use it mostly for measuring parts I print for accuracy/curiosity. 🙂

I'm not sure what the "obvious ones" are. There are plenty of articles/videos that talk about this; it's largely dependent on what materials you're printing with. (Is hairspray a "tool"? 🙄 )

I've only tried the stock PLA so far. I've only had one issue with adhering to the deck (weird print), and that was solved using some painters tape. [EDIT] WOW, does that stuff stick! [/EDIT] It kind of surprised me because, though it's a name brand, there was some ink printing on it that smudged/came off when I cleaned it with the alcohol. But it stuck! 😀

Re: getting a 3d printer...

[...] Actually, this brings me to another question: any specific tools that are of interest (apart from the obvious ones)?Based on my experiences, I'd recommend a "first aid kit" for the inevitable 1st jam consisting of the following:

  • Additional cleaning needles or bits. The single acupuncture needle you get in the box will almost certainly be lost by the time you need it. Buy a cheap kit of several. I bent a few on my first major jam before I figured out what I was doing.

  • A spare nozzle is a good thing. You want to have a "known good" one to swap in.

  • Appropriate tools for nozzle removal are essential. You will want a 16mm wrench to hold the heater block stable to avoid snapping the heatbreak. You could use pliers, but a sized wrench is much more stable and you'll be working around delicate thermistor and heater cartridge wiring. I also recommend a 7mm socket for the nozzle over an open wrench. That little thing will be HOT when it comes out. Fortunately, there's a cheap kit that will provide spare nozzles and these tools. You should be able to locate something similar in your country.

  • A soft brass brush is handy for cleaning up filament that gets stuck on the nozzle and/or heater block.

  • The printer comes with hex wrenches, but longer versions with proper handles are much easier to work with when removing fans and covers.

  • A 6"/15cm long 1.5mm solid rod is very handy for dealing with clogs. I've been able to avoid extruder tear-downs using one several times.

  • I like the eSun cleaning filament. A lot of people do just fine using white ABS, but I like the fact that the cleaning filament will melt and extrude at a wide temperature range, and it's really sticky for getting stuck filament to adhere.

  • 91%+ isopropyl alchol (IPA) may take a bit of work to locate, but you definitely need some. The 2 little 70% pads that ship with the printer won't last long. Keep the bed clean and fingers off!

  • Some 100% acetone (also may take a bit of hunting) for periodic cleaning of the bed.

  • A 3M 7445 Scotch-Brite Light Cleansing pad or equivalent is useful for occasionally roughing up the bed if the IPA or acetone are't working.

  • I second the recommendation for calipers. Spend a little more and get some with 0.02mm or better resolution. I found the 0.1mm cheap sets weren't precise enough for doing calibration.

  • Filament clips. You can print some, but I just use small binder clips. Not every spool is well thought out, and you don't want filament coming off the spool.

  • Some 2 gallon/8 liter(?) zip-loc bags for filament.

  • Dessicant packs for keeping filament dry.
  • Jams aren't really a big deal once you get a handle on them, but you'd be miserable not having a tool or part to continue on the same night.

    You don't need a lot of filament, but buy ahead so you don't run out mid-print. I've gone a little crazy and am slowly working through the the 20 or so spools I've purchased. I do recommend diving in with different nozzles and filaments. They really expand your horizons. I 0.40mm or 0.60mm hardened steel nozzle is recommended if you want to try metal, wood, carbon fiber or other exotic fills.

    Basic bed cleaning is essential to a successful print, so have those available on day 1.

    You seem to care about aesthetics and the overall neatness of your workspace. Well, good luck with that, but some drawers and tool holders will help. You'll want to keep diagonoal cutters and scissors nearby.

    A pair of diagonal cutters comes with the kit.
    I found 91% Isopropyl and 100% acetone at a pharmacy--both were very inexpensive.

    Great list, bobstro. I don't think of a lot of those items as "tools" (more like supplies) but that's my myopia. 😳

    I bought the pre-built Mk3 and only got the needle-nose pliers. The cutter on those is a bit weak. The kit has actual cutters in it?

    I found 91% Isopropyl and 100% acetone at a pharmacy--both were very inexpensive.Apparently it varies quite a bit globally. One fellow described his adventures trying to find it ... in Singapore IIRC and the complexities involved. Those are the shorts of things anybody new will want to determine quickly, before they need the items!

    Great list, bobstro. I don't think of a lot of those items as "tools" (more like supplies) but that's my myopia. 😳 Tool prep perhaps. In any case, you won't get far without 'em, so I thought best to list them out.

    Nah. Needle nose pliers in the kit, not flush cutters.

    Re: getting a 3d printer...

    Well, shut my mouth and call me cornpone, he's right. Thinking back, I found the needle nose pliers....ineffective, so I pulled out a set of 6 small pliers I picked up someplace along the line... and used one or other of those through the whole build. I had to look around to find the needle nose pair that came with the kit.

    Sorry about the confusion. 😕

I had to look around to find the needle nose pair that came with the kit. Watch out for these warning signs:

  • Compulsive collecting of useless little plastic boats.

  • Staring for hours at tiny cubes under different lights and angles.

  • Excessive ordering of filament and nozzles. Irrational justification based on one box "printing better" than another of the same color.

  • Tool hoarding.

  • Constant complaining about "bad support".

  • Declining ability to remember what was just ordered last week.

  • Avoiding family and friends to "just watch the 1st layer", followed by hours of staring at a moving widget.
  • If you or a loved one suffers these symptoms, you may be a victim of 3D Printer Syndrome, or 3DPS.

    Staring for hours at tiny cubes under different lights and angles.

    Something similar happened years ago with photography: people were looking at photos at pixel level... pointless... The overall look should be good. Pixel level looking is only ok if you suspect a problem; I feel the same applies here.


    Tool hoarding.

    That is actually the reason for me to have asked the question about tools: better get a good set of proper tools than try something cheap or that you think may work, but then ends up in a drawer never to be used. It cannot be avoided, but properly selected high quality tools are important.


    If you or a loved one suffers these symptoms, you may be a victim of 3D Printer Syndrome, or 3DPS.

    The way I'm reading up on this forum, problems that people have, possible causes and solutions; the way I'm looking at 3D model websites to see which clever things are there to print... I think I' suffering from 3DPS by proxy 😯 ...

    Re: getting a 3d printer...

    Well, I've been a hoarder/packrat of sorts my whole life (but then I've always had multiple hobbies). My better half used to complain about it, until I'd repeatedly come up with some part or other after a few minutes of scrounging, rather than spending hours looking for one at a hardware/home improvement store. Now I think she's just in awe... 🙄

    The other stuff...

  • I REFUSE to print a Benchy on principle!

  • If I print any tiny cubes, they'll most likely be board game components/tokens.

  • An order for filament, nozzles, and other sundries is in the works, but sanctioned (after years worth of quilting fabrics, thread, & paraphernalia).

  • Support--let's not go there. There IS a method to my madness (always is)... 😈

  • Anything I ordered last week is probably already on the kitchen table (or in the mailbox).

  • Avoiding family & friends is a SKILL I take pride in.
  • I'd plead, "Guilty as Charged," but I haven't been into this long enough...

    That's "MISTER Old Fart" to you!

    [...]I REFUSE to print a Benchy on principle!
    I resisted. I tried. Then I finally needed compare my results to others I was seeing online. However, by and large, I print much more manly useless little plastic tanks. The M4A1 Sherman from my tabletop wargaming days with my sons is perfect for testing angles and details.
    If I print any tiny cubes, they'll most likely be board game components/tokens.When you are up for a game of "Marvin", let me know. I'm ready. I've got quite a collection of 40mmx5mm "checkers" too, but they're all in different colors.
