BuildTak, PEI, And Early Adopter Syndrome

I’m guessing most of the members of the Hackaday community are what most people would consider early adopters. Sure, there’s variation among us, but compared to the general population we probably all qualify. I’ve spent many years being an early adopter. I owned a computer, a TiVO, a digital camera, a 3D printer, a drone, and many other gadgets before they became well known. I’ve avoided the self-balancing conveyance craze (I’ll stick with my motorcycle).

Of course, you know if you are an early adopter, you will overpay. New has a premium, after all. But there is another price: you often have the first, but not the optimum. My first digital camera took 3.5 inch floppies. My TiVO has an analog tuner.

I was reminded of this last week. A number of years ago, I built a 3D printer. A lot of printers back then didn’t have heated build plates, so printing ABS required rafts and ABS juice and frustration. I made sure to get a heated bed and, like most people in those days, I had a glass print surface covered in Kapton.

That works pretty well with ABS, but it isn’t perfect. Aqua Net hair spray makes it stick better, but large flat prints still take a little work. With a little practice, it isn’t bad. I eventually switched to an aluminum bed and didn’t have to level the head quite as often, but it didn’t really make things any better, just more repeatable.

The years pass and other gadgets beckon. I use the printer about like I use a drill press. I don’t use it every day, but when you need it it is handy. I have to admit, I’ve been getting partial to PLA since it doesn’t warp. But PLA in the hot Houston sun isn’t always a good mix, so I still print a fair amount of ABS.

The other day I noticed a product called BuildTak. I also heard some people are printing on PEI sheets. I decided to try the BuildTak. Wow! What a difference.
