3D printing was created in the 1980s. Back then it was only used for testing. There are 3 reasons for printing. Retail, Business and Testing. There are nine types of 3D printing technology:
- Stereolithography (SLA)
- Digital Light Processing (DLP)
- Fused deposition Modeling (FDM)
- Selective Laser Sintering (SLS)
- Selective Laser Melting (SLM)
- Electronic Beam Melting (EBM)
- Laminated Object Manufacturing (LOM)
- Binder Jetting (BJ)
How do 3D printers work?
3D printers use filament. FDM printing works by depositing any type of filament bottom to top. It deposits in Micro layers until the object is formed.
Filament Types
There are many types of filaments but the most common is PLA and ABS. Although you can print with practically anything. For instance, TPA bendable durable filament. You can also print with Thermochromic material, meaning color changing with temperature. Also glow in the dark filament. There are also material based filaments like Iron or wood filament.
Factors to consider when buying a 3D Printer
- When buying a 3D printer the number 1 thing to look at is the reviews. You want to see if there are minor problems or big problems from the experience of other users.
- Most likely if the Printer is 3 and a half stars and below it is not such a good printer. Read about the printer you are getting. It is a good idea to first read about the printer you picked and if you are really going to use your 3D printer .
- Any printer that is on your list should have self leveling of the plate or the printer will dispose filament too high or too low and will not print correctly.
My personal experience with 3D printers
The first printer I bought was based on the price. I looked for the cheapest printer I could find online and ordered it. It was a printer made in China and it never printed a single item. The nozzle simply scratched into the plate. Luckily, I was able to return it for a full refund. Then I spent some time reading up the reviews from printers others bought. And settled on the Flashforge Finder as reasonably priced and likely to work for me. I bought it and was able to set it up within 30 minutes and started printing. The above pictures show my printer and some of the items I have been able to print from it since I set it up.
Good Printer Costs
Just because the printer is high in cost doesn't mean it is good. For instance the Maker bot is about $2,000 printer and its ratings from those who bought it is kind of low. We got the FlashForge Finder which was $400 and in its online rating was better then the Makerbot. There are some Printers with a cost of $300 and below but don't have as much quality and wont last as long.
Printing Hack/Tricks
When printing an object you can pause in the middle which enables you to do many cool things. When we were printing a whistle, for instance, we paused it to put a ball inside to add the sport's coach whistle effect. Alos, to make something magnetic you can pause the printer and place a magnet inside. When printing you can pause and put anything in it.
So now I have started the next step in printing my own inventions. I will be sharing pictures of them here and how those are progressing.

This article was written by my 10 year old son. He is an avid consumer and investigator of new technology and just obtained his first 3D printer about three months ago. Since this blog is about all things technology and I couldn't yet have him create his own blog, I offered to have him write in mine. This article has not been edited at all. And I will continue to write about fintech and cryptocurrencies as well as genetic algorithms. (This slightly different article is not because of the fallen prices of crypto, which you will notice this blog well expected and predicted going back to two months ago, and earlier in other forum.) But I hope those who are into 3D printing or looking to get their first 3D printer would find this helpful and informative.
As my own addition, I think 3D printing going into the future, as the prices come down, could make custom parts cheaper to make relative to the cost of shipping them. This would reduce the effect of cheaper labor costs that drive manufacturing from regions with greater cost of living but higher consumption to regions with lower living costs. Long term, it also continues the shift towards greater automation, productivity, and less labor - a setback to less skilled labor. It remains to be seen if the labor force can continue to adapt to catch up with these changes in the skill sets that are being required. On the flip side, it could foster greater innovation as the distance between concept and prototype reduces with the tool it provides.
