The success of a 3D print depends on the integrity of the first layer. But only a little bit of plastic oozing out of the nozzle can break all the things. Not everyone can afford a printer outfitted with servo-assisted nozzle wipe routines to get round this downside, but you possibly can nonetheless spare a couple of minutes to manually babysit the first layer.
Good lighting, nevertheless, is the bare minimum requirement for that goal. And incorporating it in your existing 3D printer is cheaper and easier than you suppose. Here’s how you can upgrade your printer with slick LED lighting to enhance first-layer visibility.
Tools and Materials Required
Along with a 3D printer, you should have to verify you’ve these instruments and supplies ready before diving into this mission. Since this guide affords options when it comes to skills, tools, and supplies required, the requirements are split into the obligatory and optional categories.
Many of the items listed are generally present in a typical family, but you may need to buy a few of these. Although you should purchase the mandatory gadgets immediately, please learn by way of the information once to figure out which one of the optionally available objects you already have and make an observation of these that you just may need to acquire.
Nothing is as frustrating as discovering out you will have a essential instrument or part missing in the course of a build.

Step 1: Figuring out LED Strip Placement
For the majority of 3D printers sporting the Prusa/Mendel mattress-flinger design, such because the Prusa i3 or Creality Ender 3, there’s just one optimum location the place you may set up the LED strips. And that’s on the underside of the aluminum extrusion acting as the cross-member between the pair of Z-axis extrusions.
Installing the LED strip in this location is not going to interfere along with your 3D printer’s movement system, whereas shining light straight down onto the construct floor. The vertical Z-axis extrusions also serve as a handy means to route any wires safely without fouling with the motion components similar to linear rails or V-slot wheels.
Step 2: Download and Print the LED Strip Holder
Using the adhesive backing on the LED strip to attach it anywhere on the printer is a dangerous proposition. Adhesives may fail over time, which can cause the LED strip come unfastened and fall into the movement elements. That’s a recipe for electrical shorts and subsequent fires.
It’s safer to obtain and print an LED strip holder for Creality Ender 3, Prusa i3, Voron, or some other printers off free 3D mannequin repositories such as Thingiverse or Thangs. You may also wish to 3D print cable covers to prepare cables out of the way.
It’s possible to increase or decrease the length of these cable covers within the slicer software program to fit the precise dimensions of your printer.
Step 3: Selecting the best LED Strip Type
SMD LED strips can be found in a wide selection of choices, but getting the voltage rating proper is of the utmost importance. The LED strips are usually accessible in 5V, 12V, and 24V choices, with the choice relying on the working DC voltage output supplied by your 3D printer’s power provide unit (PSU).
There are a couple of how to ascertain the DC voltage supplied by the PSU. You can both get the data off the product web page on the printer manufacturer’s webpage, or you may check with the guide. In the worst-case scenario, you can bodily test the compliance label on the PSU to figure out the DC output voltage.
SMD LED strips are additionally out there in varied coloration configurations. Single-coloration cold or warm white LEDs (bearing positive. Negative terminals) are ideal for the purpose of illumination over RGB LED strips. You too can opt for high-density LED strips packing in additional LEDs per meter for brighter illumination at the associated fee of upper energy consumption.
Step 4: Wire Sizing Calculation
The thickness of the wire used to energy the led neon flex strips is immediately proportional to the maximum current drawn. It is fine to make use of thicker wires than wanted, however thinner wires are likely to overheat and trigger voltage drops.
Calculating the maximum current drawn by the LEDs is a good approach to optimize wire thickness. This is done by dividing the facility score of the LED strip by its working voltage. For example, if the LED strip is rated at 24 watts per meter and you might be using half a meter, the facility consumption of your LED strip is 12 watts.
For 24V LED strips, the maximum current drawn would come out at 0.5 amp. At half the voltage, 12V LEDs require twice the current, which works out at 1 amp. Finally, 5V LED strips would require a considerable 2.Four amps. This helpful JST DC wire-sizing chart should allow you to choose optimum wire size for your particular LED strip.
Step 5: Cut the LED Strip to Size
Cut the LED strip to dimension as per the fitting necessities of the 3D-printed holder of your choosing. Be sure to cut the LED strip solely the place uncovered copper pads/terminals are visible. That is marked with a scissor icon on most LED strips.
Step 6: Prepare the Hookup Wires
The size of the wire needs to be sufficient to bridge the gap between your 3D printer PSU and the LED strip. It’s safer to keep a margin of error and oversize the wire. You can always reduce it down to dimension later.
Using either devoted wire strippers or a sharp blade, expose about an eighth of an inch of the red and black hookup wires.

Step 7: Wire Up the LED Strip
If you understand your way round a soldering iron, proceed to solder the red and black wires to the constructive and unfavorable terminals, respectively, on the LED strip. Top that off by using both a lighter or heat gun to insulate the uncovered solder joints with heat-shrink tubing.
If soldering isn’t your cup of tea, solderless LED strip-to-wire connectors help you do the identical without requiring any tools. Just remember to get the polarity of the wiring proper. The purple wire goes to the positive terminal and black to detrimental.
Step 8: Install LED Strip in 3D-Printed Housing
LED strips normally include adhesive backing. Use that to fix the LED strip within the 3D-printed holder.
Now would be a very good time to ensure that your 3D printer is powered off and disconnected from the power outlet. Remove the mains cable from the facility inlet socket on the printer to be completely sure.
Step 9: Mount Housing to 3D Printer
Unless you fancy taking your 3D printer apart, it is suggested to use drop-in M3 T-slot nuts to put in the LED strip assembly onto the printer. Depending on the type of T-slot nuts chosen, they can either be dropped straight into the aluminum extrusion, or dropped and then turned clockwise to lock them in place.
Once the T-slot nuts are in place, align the corresponding holes on the LED strip holder and secure them into the T-slot nuts utilizing M3 button-head cap screws.
Step 10: Crimp Remaining Ends of Wires
Use the wire strippers to expose the remaining free ends of the pink and black wires. The insulated terminal crimping device will come in useful to crimp either ring or fork terminals onto the wires.
Although it is tempting to shove the stranded wires into the screw terminals without crimping insulated terminals onto their ends, doing so introduces the danger of unfastened connections and shorting.

Step 11: Connect LED Strip to PSU
Refer to your 3D printer’s manual to locate the PSU and expose the terminal block. It bears screw terminals for AC input and led linear light DC output. The AC enter terminals (marked by symbols L, N, and G) should already be populated with the mains enter wires. These shouldn’t be tinkered with at any price.
The DC side of the terminal blocks is marked by + and – symbols signifying the optimistic and unfavourable terminals. Hook up the purple wire to the optimistic terminal. The black wire to the negative terminal. Reinstall the PSU in its correct place.
Step 12: Cable Management
Route the wires into the aluminum extrusion channels in such a means that they don’t interfere with the V-slot wheels, linear rails, or some other motion system components. Use the 3D-printed cable covers to secure the wiring into place.
Move all printer axes from end to end a few instances to ensure that every little thing moves freely with out hitting the LED strip, wires, or the cable covers.
Do a Test Run
With one hand on the power switch, and ready to kill the mains power provide at a moment’s notice, change on the 3D printer. Your LED strip should gentle up the construct floor if every thing went based on plan.
Add LED Lights to Your 3D Printer: Success!
By following the step-by-step instructions, you should have now added an LED strip to your 3D printer to mild up the build surface so you’ll be able to achieve a perfect first layer.
