Electronics WITHOUT soldering?! – Light up your 3D prints with LEDs and bulbs

Robots, automatic pet feeders, movie props,
drones The list of cool projects that combine the
power of 3D printing and electronics is endless That said, some if not most of the projects
can be pretty intimidating And you can get easily discouraged when you
realize that you need to learn how to solder, write your own code for an Arduino or design
a circuit board Well, fear not, because this time you won’t need
any of that and yet we’ll light up our 3D prints You generally have 3 options when it comes
to simple light sources that work well with 3D prints And that’s LED strips, LED Lightbulbs and small diodes One of the easiest ways to add lights to your
3D prints are LED strips They’re cheap, often come with a remote, they’re available both white and as RGB and most importantly, they’re really easy to power You could buy a whole roll of LED strip and use your own LED controller and power
supply, but not this time, we said no soldering So instead we suggest buying an LED strip
with a USB connector This way, you can power it with any old phone
charger, your PC, or a power bank The obvious downside of USB is its limited
power so you can’t get really long or extremely powerful LEDs But really powerful LEDs also run pretty hot, so we wouldn’t want to use them anyway,
especially with PLA LED strips always come with a double sided
tape applied to their bottom side So it’s really easy to install them
If you stick them on the inside wall of a box you can get nice and even illumination Then print a front plate with a text or a logo and you’ll end up with a similar result
as our recording sign Alternatively, you can print and wrap a cylinder
with the LEDs and this way you’ll have the light coming from the center of the object Consider printing a diffusor from, for example, clear PETG That will make the illumination more even and hide the individual LED chips A cool thing about LED strips is that you
can cut them with regular scissors to adjust the desired length The spots were you can cut are always clearly marked so make sure to watch out for them Oh and LED strips work great as a light source
for the build plate Using lightbulbs with 3D prints is pretty
straight forward For example, if you want to print a hanging
lamp simply pick a shade you like print it, which can usually be done without
supports And then you just have to buy a lightbulb
socket with a cord and attach it to your 3D print Oldschool light bulbs were terribly inefficient
and produced a ton of heat Luckily for us, LED light bulbs are
mainstream these days And the amount of heat that they produce is significantly lower Still, be mindful of this and check how hot does your light bulb get You’re most likely not going to 3D print
all of your lamp shades maybe just a few of them as a cool design piece In that case, modern smart bulbs are a great way to make your creation even cooler They can be controlled with a voice assistant like Google Home, Amazon Alexa or Apple Homepod
and change color on demand Hey Google, turn the lights on (Google Home) Sure, turning two lights on Here are some smart light bulb options There’s the Xiaomi Yeelight, which is significantly cheaper than the competition, yet fully featured Then there’s Phillips Hue, which is expensive, but lots of fancy accessories And then there’s LIFX, which is also expensive but has greater maximum brightness Whichever lightbulb or cord set you choose,
there is one challenge in front of you And that’s hooking up the power Mains electricity voltage can seriously burn you you or even kill you So if you don’t know what you’re doing please just stop right here and consider asking
someone with more experience for help But if you know what you’re doing it’s
as simple as switching the circuit breaker off triple checking that it actually is off,
connecting the phase, which is brown or black, and the neutral cable, which is blue, insulating
the connection and turning the power back on Most cord sets even come with a quick release mechanism for the cable connection The two previous solutions were for rather
big prints In contrast to that, individual diodes can
be really tiny and fit almost everywhere They’re usually powered by 3.3V, which is
(un)coincidentally the voltage of most button cells For under $10 you can get a set of hundreds
of these diodes in various colors which will usually last you, well, forever. To attach the battery to the diode, you can
either use a rubber band or a printed part We’ve used this technique in our Halloween
crow and in our miniature tabletop gaming video We’ve just scratched the surface with using
electronics in 3D prints But adding even a small light to your 3D print
will really make it pop Would you like to see more videos about electronics
and 3D printing? Let us know in the comments
And as always Happy printing!

    what about a video with nice mods for the prusa i3?

  2. sideeffectdk says:

    Niice starter on lighting up your 3D prints. Yes, please do more electronics videos, I love seeing creative ways to use 3D prints and getting ideas for cool projects.

  3. wpherigo1 says:

    Excellent video! It would be great if you could do a few small projects end to end so your viewers can see the whole process. I’d like to attach a small led strip to my 3d printer so I can light up the work in progress. I’d like it to turn on/off with the same switch I use to turn the printer on, for instance. Thanks!

  4. mr. m says:

    Some cool stuff here. For sure, make more videos with rgb/led bulbs and strips. 🙂

  13. Rab9 says:

    Electroboom is the prime example of things you shouldn't do around electronics lol.

  14. Stephen Boyd says:

    How about an easy to follow LED clock. I've seen a couple of videos about them but they never go into detail about exactly how to wire everything up and how to attach an arduino etc.

  15. jessejamesb says:

    lets see some cool mmu prints with conductive filament

  16. kf7tkj says:

  23. Stephen-TheLightSpeed! !! says:

    Where do I find that LED clock that was shown?

  24. zapro_dk says:

    0:35 that is some seriously shitty soldering going on there 😀

  25. zapro_dk says:

    05:03 Noooooo those wires are NOT stripped enough for a secure connection. You wouldn't do that on a printer, so why in a video?

  26. Richard Boyce says:

    Great video, more please. cheers

  27. True Tech says:


  28. Tyson Gibby says:

    Yes more please!

  33. Steve Colwill says:

    yes please more videos— especially 3dprinting and electronics… this one was great!

  34. Radiation Knowledge says:

    Thank you very much .. Nice video 🙂

    I have question .. How can I get the the lightbulbs to have the same size as the base of the lamp .. The size of base of the lamp maybe different that what we download from the internet

    The base of the lamp is I mean the base which you insert (revolve) the lamp in .. I printed two lightbulbs but base in my country does not match the light bulb size .. Can someone help plz 🙂

  35. Tom Torrance says:

    More please – no issues with soldering

  41. zeropage says:

    Awesome!👍🏽But: Where is the "Recording Quiet Please" model coming from? Couldn't find it neither on Thingiverse nor is it part of the weekly 3D prints. Any pointers greatly appreciated! Cheers, Axel

  42. Andre S. says:

    Thx for that Video i found my way so far to custom Nano Leafs that are cheap to print and programmed with arduino Electronics and are open Source.
    (Prusa shared this Project on Twitter around Christmas/New Year)
    It is cooled Moodlight.
    I thought it fit perfect in this Topic here. btw 😉✌

  43. John Ullrey says:

    Yes please.

  51. Arek Wierszyłło says:

    Love Electro Boom in that video 😍

  52. Dim says:

    Cool has any one designed a lighting kit for the printer using LED strips? That sounds like a nice easy project for someone who can 3D model.

  53. Andrew Mercer says:

    Hey Josef! Where can I get the stl for that arch? It's awesome!

  54. Vipul Solanki says:

    And Prusa should start kits for such products for home diy or atleast tieup with someones for more better options by that way all in one options for diy projects can be purchased from one place to make weekend time more meaningful and creative.

  55. John Chua says:

    More Please 😀
    What material do you suggest on high power LEDs?

  56. Curtis Ward says:

    More video tutorials on this please , looks super fun !

  57. NicMediaDesign says:

    Instead of soldering I only use WAGO clamps – they are godsend!

  58. Nick's Stuff says:

    I designed a lamp shade for the Philips Hue (I like their functionality but can't stand their design):

  59. Orage says:

    super video, do you have the stl file for the 2032 battery support with led diodes?

  60. Phillip Ramirez says:

    Electronics are great subjects. Keep it basic for those wanting to learn

  61. K B says:

    Is that light bridge Opossums design?

  62. Conor says:

    Where can I find the stl of the cool geometric lamp you installed the diffuser onto?

  63. Generic account says:

    I would love more 3D printing project videos!!,

  64. Morvar says:

    Yes! More electronics videos please! Maybe with Raspberry PI family?

  65. Beril Arguner says:

    would the led light strips be a good choice or should I buy diodes instead for a ring design idea for example I would like to make a Red Lantern ring that glows in the middle from a 3D ring out the way i'd print it would be have the logo in transparent filament and the rest in red, but i don't know how to solder, could you maybe please make a video on how to make a glowing red lantern ring with a small led light please

  66. 3dprinting_germany says:

    "EASY" You are an idiot! The way you connected the L and N cable is wrong and SUPER DANGEROUS!
    Multicore wires MUST be crimped, or there is a hazard of burning!
    Sincerly, a german electrician.

  67. matneu27 says:

    Very nice inspirations. It would be quiet impossible to get a new "old school" bulb in Germany unless you know a dealer somewhere in the subway station 😉 You'll rather find a blue metallic fuse cabinet like yours.

  68. Kyle Niedermeier says:

    Great production! Yes, more videos, please!

  69. Bizilux Games says:

    what about ikea smart lights? definitely should be included as they are the cheapest lol

  70. Santa Dragon says:

    2:55 Are all your filaments in the shelf not soaking too much water and are going to be useless?

  71. Mike Slavens says:

    Great video, would love to see more about electronic projects and 3D printing!

  72. Richard Kraus says:

    I'd love to see more of this!

  73. Jens Vegeby says:

    More videos, please!

  74. Bram says:

    This is amazing! I’m just a little worried by the fact that the idler screw in the timelapses is so far through the bolt… mine is barely in. I will have to look into that…

  75. Scubaguy5 says:

    Awesome video and topic! Yes, more please! Can't wait for my mk3s kit to arrive!

  76. Florian Schatz says:

    Where is the design for this lamp 2:26?
    I want to print them 😱

  77. Asulth The third says:

    Which filaments did they use for recording sign?

  78. Paul Smith says:

    You should have printed a lock out tag out lock for the breaker

  79. id104335409 says:

    Me: Drowns?
    Yes – Drowns!

  80. SVMTech says:

    Great ideas. Can I find somewhere design for "IKEA" lights at 3:12, pls?

  81. SSlicer says:

    Please more videos!

  84. Chloe Mcholoe says:

    But I like soldering ;( (jk)

  85. Chloe Mcholoe says:

    That nighstand is beautiful i wanna make one!!!

  86. Sn4kebite says:

    Please more, very informative 🙂

    very good idea! please show us ways to use PauseAtZ for completely enclosing the electronics in a piece!

  90. Energie Z says:

    Please more electronic videos.
    Cool video!

  91. RTV Airsoft says:

    where cam i find the file for the 3volt light holder at?

  92. Henrik Brøndholt Nielsen says:

    Yes more videos please!

  93. GuitarManiac197 says:

    I would love to see more electronics and 3d printing videos! There's so many possibilities for cheap fun diy, and soldering doesn't have to be too hard once you learn. 😉

  94. Kinga Kristo says:

    Sure we want more videos 🙂 Magnetic joints?

  95. sharad jadhav says:

    yes please

  96. Jonathan Cruz says:

    👍🏼👍🏼Great video and yes please!
