3D打印探索 Deeptime 的沙子 3D 打印離子聲音系統

2020-07-09  1837

還記得Studio Akemake的Spirula Speaker嗎?它是最早的設計產品之一,表明可以使用3D打印實際上制作出美觀,功能完備的消費類產品。它是在長絲擠出工藝中使用木制聚合物復合長絲制成的,但在形式和生產率上仍然存在局限性?,F在這家名為Deeptime的公司已經發展為采用更易于生產的噴砂粘合劑3D打印工藝:其結果是令人驚嘆的Ionic Sound System,該系統由兩個被動噴砂3D打印的Spirula衛星和一個有源Thunderstone超低音揚聲器(也包括3D打?。?。 Thunderstone具有光纖,AUX和藍牙輸入,并包含為音響系統供電的電子設備。

Remember the Spirula Speaker by studio Akemake? It was one of the very first design products showing that it was possible to actually make nice, functional finished consumer products using 3D printing. It was made using a wooden-polymer composite filament in a filament extrusion process and it still had limits both in form and productivity. Now that company is called Deeptime and it has evolved to embrace a more production-ready sand binder jetting 3D printing process: the result is the stunning Ionic Sound System, which consists of two passive sand 3D printed Spirula satellites and an active Thunderstone subwoofer (also 3D printed). The Thunderstone has optical, AUX, and Bluetooth inputs and contains the electronics that power the sound system.

具有諷刺意味的是,在木材-聚合物復合材料長絲上市之前,就已經有噴砂劑的存在。缺乏的既是對技術可能性的認識,又是關于如何用它來制造最終產品而不是工業模具的新思路(確實提供了驚人的可能性,但是,如果您不在鑄造廠工作,那會很無聊而不是。幾乎和高質量的音頻系統一樣漂亮)。

The irony of all this is that sand binder jetting existed long before wood-polymer composite filaments came to market. What has been lacking is both awareness as to the technology’s possibilities and new ideas on how to use it to make final products rather than industrial molds (which do offer amazing possibilities but, if you don’t work in a foundry, are boring and not nearly as pretty as a high-quality audio system).

向我們學習使用3D打印技術來制造最終產品的砂紙粘合劑似乎需要花費很長時間。但是,一些年輕的工作室終于做到了。在Deeptime之前,Sandhelden向世界展示了如何使用噴砂粘合劑制造漂亮的設計師家具。噴砂粘結劑的事實是,它確實可以負擔得起足以生產大量設計產品的費用:但是,其采用水平仍然非常有限,因此成本仍然很高。

Learning us sand binder getting 3D printing technology to make end-use products seems to be taking a painstakingly long time. However, some young studios are finally doing it. Before Deeptime, Sandhelden showed the world how to use sand binder jetting to make beautiful designer furniture. The thing about sand binder jetting is that is could really be affordable enough to produce a large number of design products: however, its level of adoption is still so limited that costs remain very high.

現在,情況似乎正在發生變化。提供這種技術的兩家公司之一的ExOne似乎正在采取一些嚴肅的步驟來使這一過程更廣泛地可用。 Deeptime音頻系統是由ExOne的內部AM服務設施生產的,這意味著Deeptime不必購買機器-至少在其產品的預期未來需求增長要求內部遷移之前。

Now, something seems to be changing. And ExOne, one of the two companies offering this technology, seems to be taking some serious steps toward making this process more widely available. The Deeptime audio system is produced by ExOne’s internal AM service facility, which means that Deeptime does not have to buy a machine – at least until the expected future growth in demand for its products demands that they move production internally.

深度轉換 Deeptime transition

錄音室以其新名稱命名的深層時間是地質時間的未來未來概念,即“大陸舞蹈和山脈起伏的時間尺度”。因此,如果您認為3D打印需要很長時間才能發展為可投入生產的技術,請再想一想:首款Akemake揚聲器于2010年代初問世,而不到十年的時間就意味著劃時代的過渡就像大規模生產轉移到數字化,加性工作流程中一樣。

Deep time, from which the studio takes its new name, is the concept futurefutureof geologic time “the kind of timescale where continents dance and mountains rise and fall”. So if you think that 3D printing is taking a long time to evolve into a production-ready technology, think again: the first Akemake speaker was presented in the beginning of the 2010s and less than a decade is not a long time for an epochal transition to take place like the one that will see mass production shift into digital, additive workflows.

這將需要兩個以上的工作室來完成。但是,在最終使用的標準件生產中采用噴砂粘合劑的方法正與該技術在零件的金屬批量生產中的采用同步發展。而且收益越來越明顯。

It will take more than two studios to do it. But the adoption of sand binder jetting for end-use par production is moving along with the adoption of this technology for metal mass production of parts. And the benefits are becoming increasingly clear.

離子聲音系統的研究始于2014年,當時Akemake決定開發其3D打印木材概念的商業版本。在制造了50個原型之后,該公司更名為Deeptime,并從英國遷至位于布拉格附近的科學技術園區的新設計辦公室和制造工廠。

Research into the Ionic Sound System began in 2014 when Akemake decided to develop a commercial version of their 3D printed timber concepts. After fifty prototypes the company re-branded as Deeptime and relocated from the UK to a new design office and manufacturing facility situated in a Science and Technology Park near Prague.

無休止的循環 Neverending cycle

在發布全球首個砂巖產品之前,Deeptime完善了他們的生產流程,增強了音頻功能,并對每個設計方面進行了微調?,F在,它涵蓋了材料,過程和產品的最終用途,創造了獨特且完全集成的體驗。它從啟發螺旋藻揚聲器形狀的自然形態開始,一直延續到3D打印過程中使用的石英砂,該石英砂呼應了一層又一層沙子形成石頭的沉積過程。

Before launching the world’s first sandstone product, Deeptime refined their production process, enhanced the audio capabilities and fine-tuned every design aspect. It now embraces the materials, the process and the product’s final use creating a unique and fully integrated experience. It begins with the natural forms inspiring the shapes of Spirula speakers, continues through the quartz sand used in a 3D printing process that echoes the sedimentary process of stone-forming from layers and layers of sand.

就像古生物學家從沙子中挖出文物一樣,新的3D打印文物也可以從粉末床中挖出并精確清洗。然后將它們反復浸入專門開發的硬化劑中,該硬化劑會滲入多孔殼并使其不透氣。后處理完成后,將在消聲室中對完成的揚聲器進行分析,并通過掃頻到可聽范圍內的正弦波信號進行驅動。結果在視覺上令人驚嘆。整套音響的價格約為3,000歐元,我們相信聲音也不會太破舊。

Just like a paleontologist would excavate artifacts from sand, The new 3D printed artifacts are also excavated from the powder bed and precisely cleaned. They are then repeatedly dipped into a specially developed hardener which infiltrates the porous shells and makes them airtight. After post-processing is complete, the finished speakers are analyzed in an anechoic chamber, driven with a sine wave signal swept through the audible range. The results are visually stunning. At about €3,000 for the full package we trust the sound is not too shabby either.
