3Dプリンターで、木材の異方性を再現した部材を作れるか。山口さんの続き（石黒さんサポート）。新しい3Dプリンタ買ってもいい。実験精度を高めるため、もう少し試験体を大きくする。 **5/15 [#f6452115] 3Dプリンターを新しく購入するので、どれが良いか調べた。その中で、Creality3D SermoonD1 3Dプリンター オールメタルエクストルーダーというのが良いのではないか。また、せん断弾性係数の推定についての論文をもらったので読んだ。しかしあまり良く分からなかったので、再度読み直す。

**5/22 [#f6452115] 購入する3Dプリンターを調べた。しかし条件に合うのがほとんど出てこなかった。 **5/29 [#f6452115] ***やったこと [#b80352c2] 大きい試験体を作れるように、大きいプリンターを探す。また，接続方法をsdカードに絞って検索していたがあまり良いものが見つからなかったので、USBに拡大して探してみることにした。 せん断弾性係数については、後藤先生から教えてもらい、理解することができた。 以前使っていたものより、造形範囲が大きいものは以下のようなものがある。

今まで調べた条件に合うものの中で，最も大きいサイズのモデルを作ることができる（500*500*500mm）プリンターを見つけた．

**6/19 [#ve87b01d] こちらのほうが安い．レビューは一件だけであった．星5 https://store.shopping.yahoo.co.jp/ayardshop/d12-500.html フィラメントは色々使えると書いてあるが，PLAが一般的．公式が出しているものだと0.5kgで約1400円であった．相場もそのくらいだった． 3dプリンターの公式のページに使い方の動画があった．
