Replicator's FAN cover (Replicatorの出力ヘッドファンの風防) by nameless911 Oct 19, 2012

Description

Makerbot Replicator’s print head cover for more accurate print. Stop cooling printing model by print head cooling fan, and make printing better.

updated@2012/10/23 pintokitkat made PDF version. Thank you pintokitkat!

Here's thermo movie of Replicator without head cover.

Following this video, Replicator's head's cooling fan cools printing models too. Printing model's temperature should be high as stage's, but cooling fan’s exhaust is blowing to printing model. And model temperature get too low to print, and the model distorted.

Here's some picture of distorted model.

This cover stops blowing to model from the cooling fan, and make exhaust to upper.
Here's thermo video of cover attached Replicator.

The printing model’s temperature is not so low as without cover's.
And here's some photo of printed models with cover.

it's not distorted!

Makerbot Replicatorのプリントヘッドのための風防です。プリントヘッドの冷却ファンの吹き下ろしで印刷中のモデルの冷却を防ぎ、印刷精度を向上させます。特にXY方向に長いモデルが沿ってしまう問題を解決します。

風防なしの状態でReplicatorで出力した時の熱分布の動画です。

この動画からわかるように、Replicatorのヘッドの冷却用のファンは出力中のモデルも冷却してしまいます。出力中のモデルの温度はステージのヒーターの温度に近くなるべきなのですが、冷却ファンの排気がヘッドの間から出力中のモデルに吹き付けてしまいます。そして出力された部分の温度が適切な温度より低くなり、出力モデルは歪んでしまいます。

このカバーは冷却ファンから出力中のモデルへの吹き下ろしを抑制し、排気を上向きに整流します。

歪んでないでしょ、ね?

I am not sure to understand. The goal of cooling is to cool what exactly? I though the printed layers. Or should the colling be applied only to the printing spot?
Thank you for PDF version. I added PDF version to my post. If there's any problem, please te|| me.
I uploaded a photo of the one I made.  As you can see, it has its wings held curved upwards with some clear tape, so it all looks a right bodge, but it works a treat.

Instructions

1.Cut this data to kent paper with CraftROBO or SilhouetteCAMEO. Or print the PDF version, and cut red lines.
2.Wrap the paper of both side with Replicator’s stage's kapton tape.
3.Roll up side wings. db.tt/vyLerGf6 db.tt/Lvc6SMwB
4.Fold all lines. db.tt/TP3uTfWJ
5.Install the cover to Replicator. snap with double sided tape.That's all. db.tt/VabWFXJ7
Anyway, LOTTERIA’s five Ebiburger is too heavy...but delicious.

1.このデータをケント紙にCraft ROBOかSilhouetteCAMEOで切ります。もしくはPDFのデータをケント紙に印刷して赤いラインをカットします。
2.切り出した紙の両面にReplicatorのステージに貼るカプトンテープを貼ります。 db.tt/vyLerGf6 db.tt/Lvc6SMwB
3.羽根っぽい所をこんなかんじに曲げます。 db.tt/TP3uTfWJ
4.すべての折線をこんなかんじに曲げます。http://db.tt/TP3uTfWJ
5.写真の通りにReplicatorのヘッドに両面テープでつけます。以上! db.tt/VabWFXJ7

Send me your email address to pintokitkat at gmail.com and I'll send you a pdf I made for you to post.

I've made a shield and attached it to the replicator and am about to print something I know will lift.  I'll be back wit the results later.
It printed almost perfectly - just a very tiny amount of lift at the corners, but without the fan cover it would have been useless.

So, for two minutes work with a piece of cardboard this is one excellent piece of work.
Thank you for PDF version. I sent you a mail.
No email yet. Do you want to check you sent it to pintokitkat at gmail dot com?

Can you post the studio file as a pdf?
Sorry, I don't know how to export as PDF on SilhouetteStudio. If you know how, could you tell me how?
