唔是體育｜3D 打印 engine 鋼遮（活塞）❓ (Patreon)

"Additively manufacturing steel pistons has also been murmured in the paddock of late." —— 🔬 參考：Grid: In The News. Race Engine Technology, no. 125,  2020 Spring/Summer, pp.10. 

✏️ 九譯：F1 paddock 近來吹起一道風，吹話用俗稱「3D 打印」技術來製造賽車引擎活塞。

📣 短評：這是新但不是最新的風，惟被行內龍頭雜誌《Race Engine Technology》如此明目地寫下來倒是新...... 鮮。

"Despite having a higher specific weight than aluminium (alloy), an addictively manufactured steel piston with a high enough resolution would probably allow more complex geometries than a casting or forging, as it would have internal structures to carry the thermal and mechanical loads without using unnecessary material." —— 🔬 參考：Grid: In The News. Race Engine Technology, no. 125,  2020 Spring/Summer, pp.10.

✏️ 強行翻譯：儘管鋼材比鋁（合金）重，但一個由「足夠高密度（高清）」3D 打印出來的鋼活塞，將比傳統 casting 或 forging 能造出更複雜的幾何形狀。因其內部更仔細結構不需多餘物料，亦能承載熱與機械負荷。

📣 短評：我只能拋磚 🧱，希望引來相關專才的玉，多多指教。
