Hi ! I wonder what will be the big things this year in 3D Printing.
So far, I see that low cost LCD UV Resin based printers are going to ramp up and start to really become mainstream.
On the FDM Market, there are some evolutions but not revolution so far from a technology point of view, and there is not too much changes on the pricing point of view, but higher volume.
Same story on the industrial printers, no revolution, some evolution on some products, similar pricing too, but higher volume.

I performed a few queries on Google Trends to have a rough idea of what interested people in the last 12 months.
The most active part of queries performed on Google for 3D Printing is not USA, not Europe, it is Asia.
However I have a problem with the "volatility" of Related Topics and Related Queries, also it looks like there are many issues on the Asia part of the dataset.

Short resume

So far, 3d printing is not on the hype but still trendy.

• Technologies: Laser Sintering, SLA/DLP/LCD UV Based Resins, FDM
• Materials: Metal, Plastic, Ceramic
• Know-how & Manufacturing topics: CAD, Design, 3D Modelling

Another interesting part, it is to take some well know 3D Printers and have a look to the world wide distribution. You can see that some manufacturers are putting a lot of money in Google Ads, while some less, and some none.
