    I don't know in other countries, but here in Indonesia the use of 3d printers is still rare and only for specific purpose (not something that you can easily find around you in your daily life). IMO, the user-friendliness and its price are what most people here consider as disadvantages for 3d printers. Maybe due to the name is still "printer" then some people think it shouldn't be much different than conventional printers that print on paper

    3d printing ultimately never makes economic sense or practical sense for most people. With some exceptions for certain geometries, you get higher quality (although at even higher cost at low volume) with molds, and the upfront costs make 3d printing the odd item every now and then prohibitive. Their best use case isn't in the home, imo, but at local libraries etc.

    • The size of objects created with 3d printers is currently limited.
    • Traditional manufacturing of products has an enormous range of raw materials that can be used. Presently 3d printers can work up to approximately 100 different raw materials and creating products that uses more raw materials are still under development.
    • The biggest disadvantage of 3d printing is Counterfeiting. Anyone who gets a hold of a blueprint will be able to counterfeit products easily. It will become more common and tracing the source of the counterfeited items will be nearly impossible. Many copyright holders will have a hard time protecting their rights and businesses producing unique products will suffer.

    I would argue that counterfeiting (reproduction or sharing might be nicer ways to phrase that) is a benefit - perhaps the primary one. You don't have to get something at the store, or hope that a product is available. Just print it, and maybe share it.

    I agree, open model sharing is a great benefit plus it empowers people in using their own creativity.
    This is a democratization of traditional plant-based manufacturing.
    My vision is that in the end, SLS or hybrid systems (for example for multimaterial) are the way to go once they are more automated and prices come down by say, five times. I think we will be there in 10 years. The reason for SLS is speed and homogeneous visual and mechanical quality.
    Making 3D printable into a major global manufacturing technology will require overcoming some disadvantages.

    - Heterogeneity - layered product buildups leads to major failure for mechanical loads, often clean splits along the weakest layer. We can overcome this by printing truly in 3D i.e. the printhead moving also in Z-direction to create waved or zigzagged layer structures. That is why I think Scara systems will be a good approach. For multiple materials and different levels of detail, we will simply have multiple robot arms each with their own extruder working on the product.

    - Production speed - Lulzbot is handling this pretty well with the moarstruder and automatic bed leveling further automating the process.

    - Error handling, maintenance - 3D printers simply need more sensor integration for dynamic feedback to regulate the print and communicate to the user - integrated live webcams are only a start. For example, with the right software a printer can know when the filament will break, when the extruder is jammed, even what the final print should look like visually, report back errors based on image recognition and suggest new settings to improve printing.

    3d printing it is new technology and a lot of new ideas to attract people like marketing to gain more revenue.

    Here are ten things about the risks and potentially negative impacts of 3D printing technology.

    1. High Energy Consumption
    2. 3D Printing Technology is Expensive
    3. Limited Materials
    4. 3D Printers Aren?t that User-friendly
    5. Harmful Emissions
    6. Too Much Reliance on Plastic
    7. 3D Printers are Slow
    8. Production of Dangerous Weaponry
    9. Copyright Infringements
    10. Manufacturing Job Losses
