I do realize that dollar shops are bursting at the seams with cheap, plastic doodads. I'm also aware that we have little space for new junk in this apartment. Most importantly, I can think of no pressing need to start playing with this technology.
Nevertheless, I just ordered a Flashforge Adventurer 3. If I had ordered through Amazon, I could've had a device sitting here by tomorrow. Instead, I purchased though DigitMakers in Ontario because this model was considerably cheaper and I often prefer to make purchases through a Canadian supplier. This means, however, that I won't have one in my hands until sometime next week.
I feel as though I'm a little late to this game but it does seem like an applied science worthy of study. My printer will allow me to get a grasp of the basics. Many school children already have hands-on experience with 3-D printing nowadays.
