史密森學會最近決定給美國總統奧巴馬做上一尊 3D 列印的上身像。這可能是美國乃至全球歷史上第一位國家領導人接受如此高清晰度的頭像重現工作。這尊上身像之前曾出現在早些時候的白宮首次 Maker Faire（創客嘉年華）上。
史密森學會（Smithsonian Institution）是一家得到美國政府資助，歷史悠久的半官方性質博物館機構。本次的 3D 列印團隊由來自 Autodesk 和 3D Systems 公司的數位圖像技術專家，以及南加州大學創新科技研究所（USC Institute of Creative Technologies）的 3D 列印專家一同組成。
他們共同打造了一台被稱為 Mobile Light Stage 的 3D 圖像攝製機，採用 50 組 LED 對總統打光，保證總統頭部以及上身正面的各個位置在相機拍照時有足夠的光照度。這 5 0組 LED 將按照不同的組合方式營造出 10 種不同的光照場景，同時有 8 個 GoPro Hero 3+ 相機以及 6 個傳統的廣角單反相機將對總統進行拍照，在不同的角度拍下高清晰度的照片。
接下來，團隊的工作人員手持兩台拍照式結構光 3D 掃描器，在不停的閃光中對總統上身到頭部的各個角度進行幾何掃描，從而獲得 3D 列印所需的中繼資料。有了這些資料，再加上之前 Mobile Light Stage 拍攝到的（8+6）* 10 張照片當中提供的細節，團隊可以渲染出一套超精細的總統上半身模型資料，用以控制 3D 印表機列印出最終的成品。
史密森學會數位化辦公室主任 Günter Waibel 透露，在美國第 16 任總統亞伯拉罕林肯的時代，史密森尼學會使用模具將特定的塑性材料套到林肯總統的腦袋上，在鼻子處打孔以保證總統可以呼吸，最終完成了對總統的頭部模型定型。通過這種古老的方法打造出的林肯總統頭部模型，現在被保存在美國國家肖像館當中。而現在，最先進的 3D 列印技術已經與學會的古老使命結合在了一起。

對於名人明星來說有兩項最大的榮譽：一，拿到自己所在領域內的專項大獎；二，用蠟像的方式被杜莎夫人蠟像館永久保存。但最近，第二個任期即將結束的美國現任總統奧巴馬，再度利用了自己的地位領先全球：成為第一個將上半身數據3D化，擁有3D列印頭像的美國總統。
