How-To: 3D Printed Batarang: Part 3

Welcome back, nerdy friends to crafty part of my blog. We continue to work on the our 3D printed Batarang. It has been about two weeks since we last left off. Part 3 is on gluing the plastic model. Fortunately, this is one of the easiest but time consuming parts of the build. Good thing you have me to walk through it.

Tools

  1. Five-Minute Epoxy
  2. Super Glue
  3. Sanding block 
  4. 5-10 Nail files
  5. 1 popsicle stick
  6. Craft/hobby knife 


Featured in the picture above is one of two of my 3D printed Batarangs. Most prints will come out looking like this. Your first step is to cut off the excess of the plastic if you have any. For me I did to keep a stable base while printing. You are going to do this for both of Batarangs. Make sure you don’t cut the mortise and tenon joint that we create to join those pieces together. You will be left with some extra plastic pieces, so do what you want with them.

Your next step is to take the right and left pieces of one Batarang and glue it together. This should be fairly easy. First, dry fit the joint to see if they fit firmly. If it is too firm, sand a little off with one of your nail files. Retest and sand if necessary, until you get a firm fit. Once you achieve that, wipe it clean with a cloth to get rid of excess dust. Take your super glue and apply on one side only. You can pick any side. Making sure that you apply to the whole joint for maximum hold. Wait till that dries, then you can rough up the backside of the Batarangs with your sanding block. Just enough to create strong grip for glue to hold.


Good, you are almost with gluing. Your Batarangs should look roughly like mine. The final step is using the five-minute epoxy. This stuff stinks so use this in a well ventilated area. Also, use a discarded box side or some old newspaper to mix and apply. Mix up the epoxy as the direction say on the back of the box. Using that popsicle stick apply a thin layer on the back surface of both Batarangs. Sandwich one on the other. After that is done, you will have about a minute to adjust the model. Take some heavyweight items to lay over the Batarang and leave it to set overnight or as your epoxy states. 

There will be excess glue coming out but that is okay we will cut that off in the next part. Thanks for joining me for part 3 of our build. I can’t believe that this idea of a Batarang is actually in my hand. It is so cool what technology can do for us.
