今日生果介紹左部 炭纖3D打印機 , 好似幾吸引, 打印出黎既野堅硬好多.
上網搵黎睇下, 價錢就唔多吸引, https://markforged.com/order-mark-one
唔知有無 ching 會買黎試.
又或者會唔會有人嘗試去改機, 唔知要點改至可以用到?

講就好似好強. 只係... 示範片段中的成品, 都只係叫訪問的人 用手去感受一下 係唔係好硬, 仲要明顯係就住來. 而且... 一係就無比較, 一係就跟尼龍比. 作者自己對自己的產品也無信心, 叫人點可以有信心? ( 有信心的話, 早就應該已找來 ABS PLA 和 他的新物料 印的東西 , 做負重至破壞測試 + 拍片上網.)
先觀望一比較好....

如果佢deliver到佢所講的強度 (比6061T鋁還好小小), 真係好正. 但佢部機貴到無論, 料錢我未搵到但估都好貴. 咁, 暫時以相同付出前題下, 我不如買部CNC正正經去銑鋁或甚至鋼/其他金屬. 希望有日呢個方法會平落嚟等平民都玩到啦.

If they are using carbon nanotube, that will be great. You can only order the Carbon Fiber and which seen using some special nozzle, not the normal one.

以小弟睇過用炭纖製造嘅紀錄片，並唔係單單鋪一層上去咁簡單，
要鋪幾層，仲要好似做夾板咁樣，將啲炭纖布紋理交叉重疊，
特製膠水，真空吸索定型，再加焗爐侍候先至得！

The maker said the filament contains continuous carbon fibre inside, but I think its product strength is not comparable to traditional carbon fibre counterpart, because the strength will be highly anisotropic in this case. The junction between filaments do not improved on the paper at least.

1.5kg 就 106, 即係 大約 70 蚊美金 1kg, 而 makebot 原裝既 ABS 都要 48蚊美金, 以原裝對原裝比較既話, 又唔係貴好多.
不過, 家陣玩開 cheap cheap 既淘寶膠, 幾十蚊人仔, 相差就好大了..

可能 打印出黎結合得唔夠好, 外面包層膠穩陣 D , 同埋外觀好睇 D 掛.

oic, 咁即係如果用 炭纖 每一 part 就要一條絲直落再切開? 又好似無乜可能.
另外延續個傻瓜問題, 如果本身唔係拉絲, 一條長長既炭纖係點做既? 我只係傻瓜瓜諗緊, 佢又無可能模擬番本身炭纖既製造過程去打印....不過, 我完全唔知本身係點做既.

if need cut by place, base on logic may be can take the laser in the extruder, then cut, but... the point is carbon fiber made by layer by layer unless they use the nanotube

我估這是筆誤吧, 兩次 NOT, 意思就反了.
I don't think ... is comparable to ... <= okay, 意思是 前者功能較差
I think ... is not comparable to ... <= okay, 意思也是 前者功能較差
I don't think ... is not comparable ... <= 意思就變成了 兩者功能相若, 而且同一個意思 用兩次 NOT, 文法也不對了.

oic, 咁 nanotube 係咪會無 graphite 咁硬淨?
我估 nanotube 都應該比 ABS 硬淨好多掛...其實家陣 ABS 印出黎, 都已經幾硬淨下. 當然, 當工具用就更係唔得, 表面好易凹.
不過, 如果佢打印完表面都要加層膠,當工具用都只可以好大件...好似佢隻士巴拿咁. 否則, 我諗 10mm 既都未必得, 一扭既話, 內部夠硬, 但外層會凹, 好易打滑.

最早嘅炭纖係要用棉花紡紗，入爐炭化再上膠，有冇新科技就唔清楚。

carbon nanotub講咗好多年，重話做太空電梯都要靠佢，
但係啲高級跑車、單車、釣魚捍全部都係用碳纖，
無乜點聽過用碳納米管做嘅產品！

我嘅意思係碳納米管係實際應用層面，可能有技術問題，
一係就成本好貴無廠敢用，無理由咁耐都未普及，
師兄如果買咗，最好開返個評測post,等小弟開下眼界，
睇下佢到底係龍定係蟲！
