3Dプリンタツイートシェア▼Today, various 3D printers are overflowing in the world, such as those that can be easily reached by individuals, those with ultra -high accuracy, and those that can be assembled by yourself.However, on the other hand, there are voices saying, "I bought a cheap 3D printer, but I couldn't print it neatly ..."
そこで、「自作3Dプリンタを組み立てよう！」 の大人気を受けて、始まりました「3Dプリンタを改造しよう！」です。
In this series, we will remodel the 3D printer with the goal of "printing more neatly", "making a 3D printer with more attachment", and "understanding more about 3D printers".After the remodeling, we will compare how accuracy has changed compared to after assembly.
今回、改造に使う3Dプリンタはボンサイラボの「BS01+」です。
When purchasing BS01+, you can choose a "assembly kit" that you assemble according to the manual, or a "completed version" that has been assembled.When the purchased product cannot be used due to a failure or trouble, you can also choose an optional "Completed version of an alternative machine service" that allows you to receive the same -day replacement machine.
In addition, there is a Facebook community exclusively for BS01+buyers, where every day, "I would like this if I did this ..." to the happy report that "this was the case!"There is a better and more discussion to use.
そこで今回改造するのは、BS01+のFacebookコミュニティーで「この改造をしたら精度がよくなった！」と報告されている「ファンダクト」です。
What is a foundation?
As the name implies, the "duct" of "fans" is a guide for the air sent from the fans on the head where you want to cool down the motor or cylinder.It is a very important part that affects the "heat", which is the key to the 3D printer of the FFF (thermal melting laminated) method used this time.
However, many people feel, "Is it really better just by attaching these parts?"Let me explain that.
The FFF 3D printer is molded by heating the material (filament) in a softened state, cooling and hardening.
If the extruded material does not solidify while it is hot, it will deform or hang, and the modeling accuracy will be worse.Therefore, by guiding the wind in this new foundation and applying it to the material that is pushed out, it can be beautifully shaped.
しかしここで注意が必要なのは、材料がABSの場合です。ABSは、造形中に急冷すると収縮して反ってしまうことがあるので、ファンダクトを使用しない方がよいです。このファンダクトは、PLAでプリントするときだけに使いましょう。
