Over the past year or so, we have really begun to see musicians and designers utilizing 3D printing technology in order to create unique, custom, and incredibly sounding musical instruments. We’ve seen everything from guitars to cellos, flutes and violins all fabricated on 3D printers of all kinds. Most of these instruments have been created either on FDM/FFF based 3D printers similar to those found on many of our desktops at home, or large industrial level selective laser sintering (SLS)machines. Now, however, one musician, named Laurent Bernadac had taken things up another notch. Laurent Bernadac, you see, has taken it upon himself to create a fully playable electric violin which has been printed using stereolithographic (SLA) technology. This has allowed him to create one of the most astonishing violins you will ever see. [在過去一年左右的時間，我們確實開始看到音樂家利用3D列印技術設計創造獨特的令人難以置信的動聽樂器。我們已經看到了一切各種3D列印機製作之吉他到大提琴，長笛和小提琴。大多數這些文書已經建立或者在相似於我們的許多台式機在家裡，或大型工業級選擇性激光燒結（SLS）的機器發現FDM/ FFF的3D列印機。現在，然而，一個音樂家，一個名為Laurent Bernadac 採取的事情了另一個缺口。Laurent Bernadac，你看，已經使用 stereolithographic（SLA）技術印製他自己創建一個完全可玩的電小提琴。這使得他創造一個你永遠不會看到的最令人驚訝的小提琴之一。]
Called the 3D Varius, not only does it play crystal clear music, but its bout (body), neck and the majority of the rest of the instrument is 3D printed in a clear material as well. [ 叫 3D VARIUS，它不僅起到清澈的音樂，但它的 bout（體），頸部和大部分儀器的其餘部分是透明材料3D列印。]
Bernadac’s design is actually based on a Stradivarius violin; a violin which was built by members of the Stradivari family during the 17th and 18th centuries. It is 3D printed in one single piece, which strays quite a bit from traditional violin production, using UV light to cure a liquid photo-reactive resin. This method of 3D printing builds up highly detailed and precise objects in a matter of hours.
Once the violin was 3D printed, it required a quick clean-up before being put under a strong UV light in order to completely polymerize the entire structure. This ensures that it is completely cured and as strong as can be. Then the surfaces of the violin, which comes into contact with the strings or the musician’s body, are sanded down in order to “offer optimal playing comfort”. It’s then off to stringing the instrument, a process which must be done with complete precision and care in order to ensure that it plays with the clarity it is capable of.
While Bernadac says that the violin is fully 3D printed, in actuality it isn’t entirely fabricated on a 3D printer, as of course the strings are not 3D printed, nor are the tuning pegs. However, the majority the instrument in fact is.
As you can hear in the videos on this page, the violin’s sound is as crystal clear as the instrument itself. Could SLA 3D printing prove to be the preferred printing method for 3D printing musical instruments? Bernadac’s 3D Varius may prove this to be true. What do you think about this unique, yet beautiful 3D printed violin? Discuss in the 3D Varius forum thread on 3DPB.com.

The term "techno-utopian" is helpful for referring to people who believe technology alone can solve the world's problems. The term is rarely used literally. But if the financial services company Morgan Stanley is to be believed, driverless cars will literally bring about a utopian society in just over a decade.
Business Insider has this slide from Morgan Stanley about the future of Tesla Motors. The chart looks at projections for autonomous car capabilities and by 2026 it predicts a "utopian society."
One can't help but wonder if "100% autonomous, utopian society" was maybe meant as a harmless chucklegoof that didn't get edited out before publication. Joke or not, there are indeed plenty of people who are putting their eggs in the self-driving car basket.
對於物聯網的未來，Gartner認為直到2018年市場上都不會出現可主宰物聯網生態體系的平台。Gartner 另一名研究總監 Alfonso Velosa指出，有關物聯網的標準或生態系統都仍在發展中，且許多目前運作中的物聯網專案供應商或生態體系可能會失敗，企業資訊長應該要確保其主要的系統可滿足未來需求的專案策略，對於一個涉及數十年基礎設施的專案來說這格外重要，以閘道為基礎的架構將是物聯網專案能否經得起時間考驗的關鍵作法。
