Lisa Harouni: A primer on 3D printing
This is a good introduction on where 3D printing is right now. However I have to make two comments;
1) With this technology we will “in some cases abolish manual labour, which is great.” It is, if that labour is repetitive and low skilled but if that labour requires highly skilled technicians that are the custodian of generations of accumulated knowledge and that knowledge and skill forms a part of their identity then I would concede that this is the price of progression, but a pretty high cost.
2) To insinuate that sending CAD data to a regional printing buro / service is environmentally friendly and has a lower carbon footprint is not only unsubstantiated but disingenuous. The material to make these artefacts is shipped globally, individual artefacts are then posted regionally. There is as yet no recycling / material labelling policy being discussed let alone implemented. The notion that 3D printing is green and eco friendly must be dealt with seriously as carte blanche comments can be very misleading.
