Wyqid's Bed Tack


Ok all my mad scientists and homebrew chemists out there, it’s time for a little alchemy. I proudly present to you the greatest thing since loaded nachos:
Wyqid’s Bed Tack.

    Once you go tack you never go back. No more glue sticks for you my friend. (I hope you were not using hairspray…) This simple formula will give you amazing bed adhesion, easy release when your print is finished and the bed is cooled, and cleans up with just a few swipes of a paper towel and distilled water.

So what is Wyqid’s Bed Tack?

Patience grasshoppa…. Patience. 

    Let’s talk quickly about how you use it. When freshly made, the formula is a very low viscosity liquid. That means it is not thick like syrup, but flows like water (distilled water is the primary ingredient, like the soda you just drank). It is applied in just one extremely thin coat. Just enough to give your bed a shine. It is applied with a sponge so you use a very minimal amount. You do not pour it on, just 3 to 6 drops will cover your entire bed. One small 8 ounce bottle should be enough for hundreds, if not thousands, of prints. 


    To make application easy, you should use squeeze bottle and sponge or sponge-style paint brush. You can find them at your local dollar store usually, or you can get them pretty cheap online.

How does it work exactly?

    When your print bed gets hot it activates the formula and actually gets more sticky. A nice little chemical reaction from drying slightly. It also serves as a protective wafer-thin layer between your print and the bed surface. Once your bed is cooled to room temperature, your print should come off very easy. When cooled, the formula has a reverse chemical reaction and does not stick to plastic. The bed might feel just a little sticky once cool, and you can see the glossy look of the previously fresh tack is now dull in appearance, but it's still there and ready for the next print. Added bonus: It doesn't usually leave any print lines. Yep. You heard me right. 

    If you are ready to print another object right away, you can simply swipe some fresh tack over last layer and make it shine again. In practice you actually can print multiple times without using another coat of bed tack. 

Between prints I usually dampen a paper towel with distilled water and give it a quick wipe. This renews the existing tack still on the bed. You should only do this for maybe 5 or 6 prints, or if the bed no longer feels slightly sticky. Either way, after 5 or 6 prints or a few days you should wipe all the bed tack off with a damp paper towel and apply fresh tack. (I'll explain that more below.)

There is no scrubbing or scraping involved here people. There is no need to apply a lot of pressure. The magical tack is very water soluble.

Ok, I got it Mr. Wyqid. How the heck do I make it???

Without further ado, let's get cookin.

Ingredients:
  • 8 fluid ounces (1 cup) of Distilled Water
  • 1 teaspoon of PVA glue (School glue, you know… Elmer’s glue. The white or clear kind is fine)
  • 1 teaspoon of Distilled White Vinegar
  • 2 teaspoons of Unflavored Gelatine Powder. 
I have included links below to buy all the items from Amazon if you cannot find one of them at your local grocery store or that giant blue and gray mega store that provides China with half it’s GDP. I forgot the name but I think it starts with a W. The distilled water (and probably the distilled white vinegar) you should probably just buy at the grocery store. A gallon of water is heavy and cost extra to ship because it's a liquid. You'll pay $12 a gallon online, but only about $1.69 a gallon locally. The unflavored gelatine powder and white school glue is cheaper online. You may also have a hard time finding the unflavored gelatine at your local store, probably because you are looking in the wrong section of the store. It's often with the baking goods, or where they keep the stuff for making your own jellies, jams, and preserves.

Once you have the ingredients, read the directions below FIRST. Don’t just start mixing stuff or you might be vaporized. I’m just kidding. There is absolutely nothing dangerous about the formula. But if you want it to work right, follow the directions.


Directions:

Step 1.

Heat the distilled water for 1 minute in the microwave. Or be lazy like me and have Keurig make you 8 ounces of hot water, which is a lot faster (60 seconds or so). It does not need to be boiling, just nice and hot.

Step 2.

Once your water is hot, stir in the unflavored gelatine powder until it is all dissolved.

Step 3.

Next, add the PVA glue and distilled white vinegar and stir until everything is thoroughly mixed. 

Step 4.

Allow the solution to cool to room temperature.

Step 5.

Congratulations! You are officially a basement alchemist. Pour the liquid into your squeeze bottle.

    Now squeeze a few drops along the edge of your sponge and spread it evenly across the entire bed surface. Paint the fence Danielson.

    Remember, we are not trying to soak the bed and get it sloppy wet. A very thin shiny layer is all we want. Less is more. The bed can be cold or hot, it doesn’t matter. I usually apply it to a cold bed and the glossy coat will become more of a matte finish when heated. You are now ready to rock.

    Keep the sponge brush in a zip-lock style sandwich bag so it doesn't dry out and harden. It should basically never dry out, but you might want to clean it with WATER ONLY on occasion because it will collect little bits of filament and dust.

NOTE: I've switched from sponge brushes to just regular dish sponges. They are much tougher and last longer. Your skin and fingers naturally have oils in them that you don't want on your print surface. I cut the corner off of one end of the sponge so I know which side I use for holding the sponge.

Shelf Life

    Wyqid’s Bed Tack should has a shelf life of a year or so.  The only biodegradable thing in it is the gelatin. The solution is acidic enough to be very resistant to bacteria. Do not refrigerate the tack.

One Application Last Several Prints

    After a print you can refresh the bed tack simply by using a paper towel moistened with distilled water (thats why I keep a spray bottle of distilled handy) and wiping the bed a few times in each direction. This redistributes the leftover tack still on the bed. One coat might last you up to 10 prints or so. 

You should always wipe the bed with distilled water and a paper towel to prevent old tack from building up. Just a friendly reminder: Spray the water into a folded paper towel, don't ever 'spray' anything towards your 3D printer. 

Gel-o-rific

    The formula will become less watery and more like a gel after a few days or so, this is normal. One tiny box of gelatine powder will make a boat load of tack since you only use a teaspoon at a time. I've been using it a year and I've only used 1 packet out of the 4 packets that come in a small box.

 Just getting started here. Deciding on a plan for the right layout and got some css and html to write as well as some graphics and icons to design. This isn’t my first, second, of even 100th website. Could be a little while. We shall see. What I do promise is to give it to you straight. No influencer garbage.  What you will get is a taste of my own experience, science, and opinions. I’m notoriously cheap, but when I spend money I do my research and weigh the cost versus the quality. You’ll soon know what I know, which is what works for the right price. Maybe you won’t agree with my take on some topics, and thats fine. I’m entitled to my opinion, and you’re entitled to be wrong… or right. If you give me a better solution, I will evaluate it and I may agree with you. I’m loyal to no brand. I know a Toyota is a high quality car, and I know a Lexus is a Toyota under the hood. They both appeal to different customers: one who wants bang for thier buck, and the other who likes to wear their

One USB Cable To Rule Them All

Yes, I solved the  3D Printing USB Cable Problem .  As many have experienced, USB connectivity to many printers has a lot of issues. Either your printer is not even detected, or the connection is dropped and your printer stops printing. This is especially common if you use the Raspberry Pi because it does not come with a shielded case to protect from EMF interference. Now a lot of veteran 3D Printing hobbyists will say the problem is that you are using a low quality cable. This is simply not the case. The cable has to be wired differently and shielded using two methods combined. I'm going to show you how to turn the most dirt cheap cable from the dollar store into the best 3D printing cable ever. I've made several, and they never drop connection or not detect my printers. Unfortunately this will require me to make a YouTube video because building the cable is slightly confusing for the average person. I have no aspirations to become a YouTuber although I have had many YouTube c

Latest Design: Paper Towel Holder

I use paper towels in the lab all the time. I needed something to hold the spool. If I can print it, why buy it. There are lots of paper towel holder designs I can download and print, but I wanted one that can be mounted onto pegboard because I have a huge pegboard wall that takes up one whole side of my room and half of another side. So for anything I design that can be wall mounted, I align the holes so pegboard is an option. Download STL from Thingiverse
