| 風扇規格：無刷直流風扇 4010S = 40 x 40 x 10 SLEEVE（油封） 油封壽命最短，沒有油就會發出聲音＊註 |
 |
| 風扇背面貼紙撕開，中間有一個扣具 建議風扇有問題的網友，進行到這一步之後 將 WD-40 從此處加入，先試試看是否好轉 如仍然無法改善，再往下一步測試 |
 |
| 4010的背面扣具實在太小，不小心就破壞成這樣了 |
 |
| 拆開扣具之後，風扇很容易取下（直接取出） |
 |
| 將軸心清一清，裝回去試試看 |
 |
| 中間的部分也很容易卡髒污 |
 |
| 一不小心就把漆包線拆壞了，非常脆弱 風扇如果拆成這樣就沒救了 |

2012年四月，阿姆斯特丹的醫療中心醫院啟用了內部祈禱室，提供病人與其家屬一個可以度過難關的空間。
In April 2012, the Medical Center Hospital of VU University Amsterdam opened its Silence Room, a place where patients and their families can stay for going through their difficult time.
這個空間是癌症中心的一個部分，由 D/Dock，荷蘭的設計團體所操刀。如該團體的建築師 Francesco Messori 所說，這個設計的構想源自於他年輕時的義大利之旅。＂小時候我常和家父一起上教堂。我們通常會待在教堂的後段，靠近唱詩班，在那裏讓我感覺到被保護、有安全感。這些正是我想要在這個設計裡達到的；一個讓你能擁抱平靜的地方。＂
This space is part of Cancer Center and Day Surgical Centre previously designed by D/Dock, a Dutch design studio. According to D/Dock architect Francesco Messori, this design was inspired by his journey in Italy when he was young. "As a small child I often went with my father to church. We usually sat at the back of the church, near the choir, where I felt safe and protected. This is exactly what I wanted to achieve in this design, a place that embraces you in its serenity."
在這個祈禱室裡，自然的材料（比方石頭、木頭）被用來營造一種帶有保護與安全感的空間。在與 D-Shape 3D Printer 的發明者 Enrico Dini 先生合作後，整個團隊開始使用了 3D Printing 的技術，來生產具有石頭質感的元件。D-Shape 3D printer 以不段堆疊砂粒的方式製造出3D的物件，並利用黏合物（binding agent）來強化整體的結構。
In this Silence Room, natural materials such as stone and wood are used to give a sense of protection and security. In collaboration with Enrico Dini, inventor of D-Shape 3D printer, the team manufactured the stone items using 3D printing technology. The D-Shape 3D printer built 3D objects by placing layers of sand on top of each other and used a binding agent to hold the structure together.
透過效果燈、蠟燭、以及自然物件的陪襯，D/Dock 成功地營造出一個讓病人與摯愛都能得到慰藉的地方。"那是一個極度需要思考的空間，在開幕前看到人們心存感激地使用它。它提供醫院日常生活裡，喧囂和熱鬧間的喘息。" said Janette Delver from Pastoral and Spiritual Care.
Using effect of light, candles, natural products, D/Dock succeeded in creating a place for solace and reflection for both the patient and their loved ones, regardless of religion and background. "There was a great need for contemplation space." said Janette Delver from Pastoral and Spiritual Care. "Even before the opening I saw people using it gratefully. It offers a respite from the hustle and bustle of daily life in hospital."
這篇文章主要是紀錄 MakerBot 一代的 Replicator 雙噴頭機型
可否以最簡單的方式，改裝成可以列印 PLA 材質，有風扇側吹的 R2 機型
不管成敗，相信都有一些意義在。希望可以對有相關興趣的網友有所幫助

下圖是我清機器時順便拍的風扇規格，手邊機器是山寨版的R1_D
用的是相對便宜的油封風扇 24V 4010s 0.15A
代表的是24V 尺寸40 x 40 x 10mm S是油封軸承
改裝 R2 所使用的風扇部分，我是購買24V 5015B 0.13A
代表的是 24V 尺寸 50 x 50 x 15mm B是滾珠軸承
原因無它，我深信 R2 是用 DUAL / R2X 去改的
所以風扇應該是沿用原本左噴頭的風扇規格
滾珠軸承的好處是，壽命長，較油封軸承耐髒耐灰塵（推薦！）

| 我買了兩個（單價18 RMB），寄出約兩天可收件 順豐到付運費是168元 |

| 組裝前照片 |
 |
| 目前組裝進度是....組裝完成（不需修改模型） |
 |
| 風扇的電線是在前面，與官方的版本不同 但是在淘寶上沒有找到相關的版本。另外電線有兩條與三條之分 多出來的一條式測速線，並不需要買三條電線的版本 |
 |
| 列印PLA的關鍵除了溫度設定之外（MakerBot R2 設定為230度） （其他機種設定為170度，主要是測溫裝置與加溫裝置的誤差） 最重要的構件應該就是額外加裝的出風設備，讓PLA快速從水狀降溫凝固 |

| 出風口特寫，正好會繞過噴嘴從左側吹入冷空氣 |
今天中午前聯絡的對岸的 3D Printer 廠商
他們說五月會推出 PLA 的新機型，於是我詢問了是否有風扇側吹的部分
他們回答是沒有，但是他們改良了喉管的部分設計
我想有拿手邊機器印過 PLA 的朋友應該知道喉管的散熱成敗會是個關鍵
然後他們說機器列印PLA時的溫度是170度，這與MakerBot官方資料相符合
至於風扇的部分，由於本來上方的風扇就會有向下的氣流
也許上面這些裝置是為了230度的列印而設定的，170度不需要？（待考證）

獨特的、 獨一無二的建築元件、快速生成、符合經濟效益的.... 從先進的三維建模軟體發展直到現在，在 3D 列印的世界裡，這些關鍵字是還沒有被兌現的。傳統的 3D 列印作為一種設計工具，是成型過程中昂貴的一個環節，但往往又是生產中最重要的部分。然而，舊金山灣區的 Rael San Fratello 建築師事務所，發表了一個扳倒這些論點的作品。
Unique, one-of-a-kind building components, generated quickly and economically from advanced 3-dimensional modeling software – until now this promise of 3D printing was unfulfilled. Conventional 3D printing served as an expensive prototyping process, important as a design tool but falling short in production. However, this year the San Francisco Bay Area firm Rael San Fratello Architects has initiated a fundamental shift.

美國加利福尼亞大學伯克利分校（UC Berkeley）助理教授 Ronald Rael 進行的研究，透過該公司已開發的水泥基聚合物，以及一個新的進程方式，首次沿用常規的快速原型製造硬體，來產生堅固而耐久的建築元件；它的成本遠低於傳統快速成型材料—比粉印刷材料的成本還要低90%。材料也達到 4,700 psi 的精密度。這一種材料是透過數位建模軟體控制輸出，將為建築材料和合成工藝的設計、生產，帶來新的時代。
Through research Assistant Professor Ronald Rael conducts at the University of California Berkeley, the firm has developed a cement-based polymer and a new process that,for the first time, employs conventional rapid prototyping hardware to produce strong and durable building components that cost far less than conventional rapid prototyping materials—up to 90% less than comparable powder printing materials. The material can also reach strengths of up to 4,700 psi in compression. This advancement in material output from digital modeling software ushers in a new era in building materials, and a new synthesis of design and production.

三個UC Berkeley的學生，三月底的時候架設了Dreambox這項3D列印的服務。他們將MakerBot的Replicator改裝，並安置在校區的Etcheverry Hall大廳內。
透過網路登入與上傳的方式訂購，用戶只需要花3-15美金（新台幣100-450）就可以得到他們3D Printed的作品。列印完成後，部分將存儲在一個上鎖的抽屜，妥善保管直到你撿起來。
In early March three U.C. Berkeley students, David Pastewka, Richard Berwick and Will Drevno launched Dreambox, a 3D printing vending machine providing automated 3D printing services.
At the end of March the first Dreambox 3D printer was installed in Etcheverry Hall at UC Berkeley. This first prototype makes use of a MakerBot Replicator and students could order prints by logging onto the Dreambox website and uploading the 3D file. After submitting the payment the customer can receive an access code for a locker.
When the print is complete, the part will be stored in a locked drawer for safekeeping until you pick it up. The price range of each print is from $3 to $15. In the future the company will also add more vendors' 3D printer to ensure more materials to be used in Dreambox.

The Dreambox founding team met in 2011 in a mobile application development class and competition at U.C. Berkeley. Their idea was accepted into Skydeck Berkeley, an incubator-accelerator program based in Berkeley, CA, in the Fall of 2012, since then the team has been designing and prototyping its first vending machine for the U.C. Berkeley campus.

| Liam's的機械手，由美國的 Ivan Owen 與人在南非的 Richard Van As 合作，並MakerBot 協助 3D printer 製造 Liam's Robohand, the product of a collaboration between Ivan Owen in Bellingham, Washington and Richard Van As in South Africa - and produced on a MakerBot 3D printer. |
不久之前，Liam還是個沒有右手手指的孩子。這位南非的五歲孩童，伴隨著罕見疾病羊膜帶綜合症候群（Amniotic Band Syndrome）出生，這種病症導致他在胎兒時期發育畸形。但是自從去年十一月，Liam 開始嘗試使用一系列的義肢（由兩個居住在地球兩端的人所設計，並由開源的3D列印技術）。
Not too long ago, Liam had no fingers on his right hand. The South African five-year old was born with Amniotic Band Syndrome, which causes amputation of digits before birth. But since November, Liam has been using a series of prosthetic hands designed by two men living on opposite sides of the planet, using open source software and 3D-printing technology.
這兩個人，Ivan Owen 住在美國華盛頓州的 Bellingham， 而 Richard Van As 住在南非，他們在MakerBot's Thingiverse 網站上發表了 Robohand 這款設計，一個可以被自由下載、供人自行3D列印的機械手義肢。他們有意的將這個設計公布在開放的社群裡，藉此希望更多無法負擔昂貴義肢費用（超過上萬美金）的人，同樣可以受惠。
Now, those two men—Ivan Owen in Bellingham, Washington and Richard Van As in South Africa—have published the design for Robohand, the mechanical hand prosthesis, on MakerBot's Thingiverse site as a digital file that can be used to produce its parts in a 3D printer. They've intentionally made the design public domain in the hopes that others around the world who don't have access to expensive commercial prosthetics (which can cost tens of thousands of dollars) can benefit from it.
這個計畫始於Owen於2011年為了參加科技大會所設計的一個機械手。他平日在學校工作，但是他在家中會創作一些奇怪的裝置。當一段由Owen展示他所設計的特大號機械手影片，如病毒般擴散開來的時候，Van As 先生留意到了這個事情－一個因為木工機械事故而失去右手四隻手指的人。Van As 被告知過，要安裝像是 X-Finger 這樣的義肢，每一個訂製手指的要價只少一萬美元，所以他打算利用他的工作室來設計專屬於自己的義肢。
The project began with a mechanical hand Owen made for a science fiction convention in 2011. He works for a school supply business during the day, but he also works from home creating special effects. When a video of Owen demonstrating the oversized hand went viral, it got the attention of Van As, who had lost most of four fingers on his right hand in a woodworking accident. Van As had been told that prosthetic fingers, such as the X-Finger, would cost him at least $10,000 per finger replaced, so he set about in his workshop trying to design his own.
Van As 先生和 Owen 主動聯繫，他們倆個開始一系列的長距離合作，並將他們的資料整理在他們的BLOG上（該網站已停止更新，並連結到FACEBOOK頁面上）。Van As 最初寄了一個以他自己的手為樣本的塑膠手給 Owen，讓他去設計。起初，Owen 必須實質上的將設計的原型寄回去給 Van As 先生－這是一個費時又昂貴的過程。
Van As contacted Owen, and the two started collaborating long-distance and documenting the project on their blog, Coming up Short handed. Van As first sent Owen a plastic cast of his hand to use as a reference for design work. Initially, Owen had to physically ship Van As prototypes—a process that was expensive and added weeks to each iteration of their effort.
去年十一月，這兩個人決定碰一次面。我們最初的計畫是，在十一月的時定案、打磨、並強化那款為Rich量身訂做的義肢。Owen 在受 Ars 網頁採訪時這麼說。但是之後 Van As 先生收到一封由Liam母親寄來的電子郵件，她透過了網站看到了他們進行中的案子。＂當 Rich 被 Yolandi 女士（Liam的母親）聯繫上時，我們決定決定跑一趟並幫Liam做一個設計的原型。我們只有三天半的時間，那是一場嚴拒的挑戰，但是我們認定在那個時空下，那是一件絕對要做的事情。＂
Last November, the two prepared to meet for the first time. "Our initial plan for the trip in November was to finalize and polish and improve the prosthesis we had designed for Rich," Owen told Ars in an interview. But then Van As got an e-mail from Liam's mother after she discovered the project online. "When he was contacted by (Liam's mother) Yolandi, we decided we would have a go at trying to build an initial prototype for Liam in the space of time that I was there as well. We only had 3 and a half days, so, you know, it was an arduous task, but it was something we felt we should definitely do while we were in the same place at the same time."
當Owen離開的時候，Liam已經拿到了了他的機械手原型，但是這仍需要一番修改。這整個流程因為一件事的介入而加速了。MakerBot 公司在一月中的時候贊助了兩台Replicator 2 3D printer，他們兩個人一人一台，讓他們能夠快速反覆生產他們的設計。＂我實在不是很理解3D printing，直到不久之前....＂Owen這樣說道。我和 Rich 對於這工具是如此的實用而感到驚訝，甚至是用來製造功能性的組件。它以令人難以置信的速度推進了我們所能做的事情。
When Owen left, Liam had his first prototype hand, but it still needed some work. That work accelerated when MakerBot donated two Replicator 2 printers to the project in mid-January—one for Owen and one for Van As—allowing them to rapidly iterate their designs. "I actually didn't really know much about 3D printing until not too long ago," Owen said. Rich and I have been amazed at how useful it is, even for producing functional parts. It's been an incredible boost to the speed with which we can do this."
Owen使用了OpenSCAD －一款開源的電腦輔助設計軟體－來完成大部分的3D printed元件設計。OpenSCAD 並不是一款即時互動介面式的操作工具；相反的，設計必須透過程式碼（scripting）的方式被創建。Owen因為有programming的基礎，所以自學的方式學習怎麼去使用這套軟體來生產他的設計。
Owen has done most of the design work for 3D printed components using OpenSCAD—an open-source 3D computer-aided design modeling program. OpenSCAD isn't an interactive tool; rather, designs are created in a scripting language. Owen, who has a background in programming, taught himself how to use the software to produce the designs.
OpenSCAD 生成的 Robohand 檔案相當的小，檔案大小在 2MB 以內，因此他們可以輕易的讓兩者透過電子信件傳遞。＂有幾次我和 Rich 在差不多的時候醒來，當我寄一個檔案給他，他把檔案列印出來，然後隨即給我一些建議。在約莫15-20分鐘內，我可以再回傳一個修正的版本給他。這種方式很像是我們就坐在彼此的旁邊一樣；整個流程從兩個禮拜縮短至兩分鐘。＂
The OpenSCAD files for Robohand are relatively small—under 2 megabytes—so they can easily be pushed back and forth between Owen and Van As by e-mail. "There have been times Rich and I have been awake at the same time," Owen said, "and I e-mail him a file, and he prints it out, and can send me feedback. And then within 15 to 20 minutes, I can send him a modified version. It's made it a lot more like working right next to each other. Turnaround has gone from two weeks to two minutes."
就在這周稍早，Liam 拿到了由 MakerBot 所製作的最後的版本。由 PLA 塑膠樹酯所製作的義肢在結構性上足以負擔每日的使用。Owen說他們嘗試了填充的百分比－一種參數可以控制物件實心的比率。從數次的測試之後，這隻機械義肢的強度已經達到與真實手臂相同的程度。這同時意味著，隨著 Liam 的成長，這款設計只需要放大並重新列印即可供他使用。當 Liam 成長完全不再發育之後，他的機械義肢就可以用金屬來製作。
Earlier this week, Liam received a finalized working version of the hand, printed on the MakerBot. The PLA plastic resin used by the MakerBot machine is strong enough to be used day to day, Owen said. We've found we can control the in-fill percentage—the ratio of plastic to air in the part," he said. "So actually, from the experiments we've done, the force to break the plastic exceeds the strength of the human hand." It also means that, as Liam grows, the design can just be scaled up and reprinted for him; when he's fully grown, the hand could be metal fabricated.
從一開始，這個計劃就打算要開放原始設計，Owen 說 Rich 和他都很開心有這個機會去做這件事。我們不只是找到了設計的夥伴，但也有志一同的覺得有些事情不該被商業化－這些事情是需要而不是想要－。這兩位將計畫去長期發展這個設計，因為實踐的門檻不用太高而且這將會更輕易的被生產，並使得全球的需求者受益。＂不過如果有誰可以利用這個設計在機器義肢上，我們很樂意和他們合作＂Owen 先生補充。
From the beginning, the project was intended to be open-sourced, Owen said. "Rich and I have been very happy to have the opportunity to do this," he explained. "Not only did we find a design partner, but we're kindred spirits in that we're both frustrated by the fact that there are some things that just shouldn't be commercialized—they're needs instead of wants—that are." The pair plan to continue to develop the design as a mechanical prosthesis in the long term because it is low-tech and could be more easily produced and supported around the world. "But if there is somebody who can utilize the design for a robotic prosthesis, we'd be excited to work with them," Owen added.
Owen 先生也希望他的機械手能夠為那些因戰事失去指節的退伍軍人們（位於國防部與退伍軍人事務部）。我住在離西雅圖不遠的地方，而Joint Base Lewis McChord基地就在附近。＂我想和駐基地的治療師談一談，如果他們有經費可以採購一台3D printer，他們就可以用這麼方式來進行－而整體的生產將會因此下降，因為老兵們不必再為專利權使用費（royalties）付出高額的成本＂Owen 先生說道。
Owen also hopes to get his hand into the hands of the Defense Department and Department of Veterans Affairs to help veterans who have lost digits or hands. "I live not too far from Seattle, and [we] have Joint Base Lewis McChord near us," he said. "I would like to talk to on-base occupational therapists. If they have the funding to get a 3D printer, they could work with this—and the cost to produce them for each veteran is brought down because they don't have to pay royalties."
Eric Moger (60)先生是一位廚房的經理，過去他飽受左半邊皮下的惡性腫瘤所苦，在他接受了擴大移除手術治療之後，切除癌細胞的部分並且存活了下來。他的生命雖然得以延續，不過他幾乎失去了整個左臉，包括他的左眼、臉頰和下顎骨。
那之後的四年，Eric先生過了非常艱苦的生活；在大面積的化學治療以及放射線治療之後，身體回復的速度也因此而停滯了，他的左臉完全是用紗布包覆著。這期間他經歷了八次的重建手術，但是並沒有很成功。
最後，Eric和他的未婚妻拜會了Dr. Christian Jessen 在Embarrassing Bodies clinic（不好翻譯這個，直接翻譯是令人尷尬的、難以啟齒的部分，還有一部電影和一個影集都是在講這樣的診所與病例，但應該有更文雅的詞....）。透過立體掃描和立體列印技術，外科醫生為Eric先生製作了一張重建的臉，也是英國相關病例的首個案例。

首先，專業的植牙外科醫生 Andrew Dawood 以電腦斷層掃描（CT scan）以及臉部掃描 Eric 先生左邊的半顱骨，並且運用軟體去建置他的臉。基於這些資料，Dr. Dawood 以鈦金屬設計了臉部的鷹架（scaffold）來重建那些失去的臉部骨骼。
藉由立體影像與列印技術，Dr. Dawood 得以利用鏡射 Eric 右臉資訊的方式，以強化尼龍材質來重建他的左臉。然後他重塑了一個新的矽膠面膜，以磁吸的方式固定在Eric先生的臉上。這是術後的第一次，Eric 可以用玻璃杯喝水並且品嘗食物。之前他每次手術後都必須夠過導管將食物和湯水直接導入胃裡。
Dr. Dawood希望在不久的將來，他們能夠直接將矽膠面膜以立體列印的方式輸出，來加速整個流程。
這意味著我們能夠為人類製作不同型態的義肢，比方一個可以讓人度假時使用的鞣皮義肢....不過我們目前離那一步還很遠。Eric 有了張新臉之後，這為他帶來了希望、樂觀、信心以及他的家人。
＂在這些都整理出來之後，我們打算結婚＂Eric 先生這麼說道。＂我打算去安裝新的假牙，這樣我就可以再咀嚼；之後我要完成我的婚禮並且重新開始我的生活。＂現在我有了一張新的臉，我可以舉辦我的婚禮以及開啟我的人生，在它停滯了四年半之後。＂
Dezeen and MINI World Tour（一個Dezeen網站與MINI Cooper跨品牌的世界巡迴計畫／這一站來到了南非的開普頓）: 日本設計師Masashi Kawamura在最新版的影片裡，談到他去年推動的pop-up 3D photo booth計畫。

關於Dezeen去年特別報導過的＂Omote 3D Shashin kan＂計畫，讓顧客們有機會去購買自己或是家族成員的3D-printed模型。設計師Kawamura先生說：＂我們希望找到新的模式，開創一種家族肖像的形式，並將它帶到下一個世紀。整個流程就是當你到達之後，我們會拿一組可攜式的儀器對你做全身性的掃瞄。人們可以直接把他們縮小版的人形帶回去，取代過去常見的平面肖像。＂

PARTY使用的是一款全彩的3D成型機，藉由它來生成具有細部的模型。這些模型的尺寸從10公分到20公分高，但是設計師Kawamura 先生相信這個技術還有很長的一個空間可以去發展。他認為 3D printing 對他而言是一個非常有趣且值得玩味的技術，但是他也認為這個技術對整體架構而言還太早。＂在進行完這個案子之後，我們會去學習更多有關艱深的技術面，以及許多可以提升技術層次與材料使用的進階＂他說。
 |

對於 3D printing 未來的可能性，Kawamura 先生還是抱持著樂觀的態度。＂接下來的這兩年內，一切都會變得更加美好；這個領域將會有重要的進步與突破。想像每個人都能夠生產自己的產品，這會是多麼有趣的一件事。＂
