3d printing is great because it is transversal: it could be at a local, personal or industrial level and it implies a massive customization.
The advent of this technique has seen a production of items, that is not the possibility tu build them physically in another way.
To build something complex you have to build first the tools to build the “thing”. Using 3d printing models, there isn’t this requirement anymore.
furthermore, because of the complexity advantages stated above, products and components can be designed specifically to avoid assembly requirements with intricate geometry and complex features further eliminating the labour and costs associated with assembly processes.
It is no accident that many libraries around the world has a 3d printing machine in their facility: there is one open to everyone in New Zeland that only costs just 1$ per hour.
3D printing is also an energy-efficient technology utilizing up to 85% of materials, creating less waste, but also adding to the product a much longer operating life, because of the lighter and stronger design, with less carbon monoxide produced.
There is no need to change the chamber of production or tools or materials if there is a special demand or your business is focused on one-shot request or if you offer massive customization. The only phase that will change is the design of the product, a digital process that does not waste materials or forces to change the production chain.
For this reasons, 3D printing is fit for a local manufacturing model, where the products are designed and made on demand in the local area where they are produced — crossing off warehouses, inventories and shipping logistics that can be sustained only by big companies. It’s no surprise that there a lot of resources online, software, search engines, and forums that can help the beginners of the 3d printing world.
