Is 3D Printing worth it?

Posted on Updated on


Is 3D printing worth it? Marius Hornberger says, “A few real-world workshop examples that use 3D-printing. I hate how 3D printers are always advertised with the things they can make. Mostly figures or models of stuff that looks cool initially, but very few people need that. That’s why I didn’t want to dive into 3D printing for some time. Since I then had access to a printer from my dad, I came up with a few things that make good use of a printer for the workshop. The materials I used were PLA and PETG. Everything white was PETG, and the rest was PLA. I use SolidWorks for designing.”

According to comments from the video,”

  • Yes, you can make parts that don’t exist and make replacement parts for existing equipment.
  • Sometimes you seem like a wise old guy who’s been around precision workshops for decades, passing on your skills to the youngsters in the audience. I’m 74 years old and enjoy being one of the youngsters. Those endless examples of your high-quality design & 3D printing had me captivated.
    -It was one of the best videos about practical 3d printed parts. Great job!
  • Genius use of 3D printing. Inspiring!
  • My 3D printer is my favorite woodworking tool. You demonstrated excellent use of it. Your designs are well thought out; I can tell you’ve spent some time on them. Well done!
  • This an excellent video highlighting the practical uses of 3D Printers.
  • The most significant negative of 3d printing is time. Granted, you don’t have to sit there watching the printer doing its job, but you still need to keep an eye on it in case something fails, and I don’t have a good feeling about letting a machine work for that long all alone. Besides that, I love my 3d printer a lot; even though it’s only a cheap version of the original i3, it still produces reasonable prints.
  • Excellent work; I also have a 3d printer (mk3 and MK2s) and a workshop. I’ve made dovetail templates, corner clamps, screw boxes, drilling templates, and more. Your designs are great; I love the chamfer interlock system you designed for the connections. Is that all in PLA?”

3D printing material, PLA.

Poly Lactic Acid or PLA is made from organic material, for example, cornstarch, tapioca, or sugarcane. PLA is used in the production of bags, food packaging, disposable utensils, plastic bags, and so on. PLA is used as surgical implants such as anchors, rods, pins, or plates. If inserted in the body, PLA breaks into harmless lactic acid within 6 months to a couple of years. The slow degradation helps the body to slowly take over the role of the implanted structure as it recovers.
Since PLA is made from renewable resources, it is one of the most environmentally friendly materials used for 3D printing. PLA is extruded at a temperature of 160°C to 220°C. Since PLA has a low melting temperature, parts made from PLA can warp under heated conditions. When heated for 3D printing, PLA emits a sweet smell similar to corn. These are not harmful fumes and therefore PLA can be used for 3D printing indoors. PLA comes in most colors including translucent and glows in the dark. PLA cools slowly and therefore some 3D printers install a fan to cool down the 3D printed material. When PLA cools down it is tough but rather brittle. PLA has become a popular choice of material for 3D printing due to its environmental friendliness and low toxicity.
