ATOM 3D Printer Group 造訪社團

Are all these models printed in one time?

It seems that cooling time isnt enough, that's why when mall feature was printed, it deformed from time to time.

3 individual prints, starting from the left most one first

You can try enable Prime pillar function which is in Support column. After finishing path it will print a pillar next to model, makes it easy to cool your model.

我也差不多，但是我有inset 0.15，這樣我孔才會準。我只重視孔。我是atom 1.0

我也是1.0，我是要開衛浴設備的模具要用⋯所以要蠻準的。不知道有沒有高手可以解決這件事⋯

說真的，我常常要組車用的樣品，一定是跑CNC樣品，工業級RP也不夠準!

我目前解決的辦法是看印出來尺寸少多少，在去做調整。

內孔被擠太多不好算...沒法1:1產生成品..孔越小可能越嚴重
這要靠切片軟體的智慧
不過目前可能沒有很會處理這個的切片軟體?
以前的skeinforge據說弄得還不錯

皮帶跟無背隙滾珠螺桿是很大的差異，更何況CNC有光學尺回饋，步進馬達跟伺服馬達也不是一個層次，控制器幾十萬級跟千元級。我建議還是把3dp用在它可以發揮的地方，要機器做它做不到的事，有時候是多浪費時間。

真的!!!
但我覺得好用的地方在跟廠商交涉平面圖的時候可以縮短溝通的時間。

1.0 +1 不過還是不太清楚為何outer perimeter first 尺寸可以較準一點?

我是預訂目前還沒有機器，只是有台舊型的FDM，我自己是買手工鉸刀來鉸孔，除了尺寸也兼顧表面粗糙度。

Flow Adjust looks not normal, the Max value should not be so big .
I would set it to around 8.( but for current select speed is not a problem. It's just a constraint to limit the max speed.

Thanks, but do you mean I should change 100 to 8?

I've been experimenting with different speed settings but haven't yet decided on which best.

Here is a picture of how my ball heads looked before and after refurbishment.

how did you do the rechromig (galvanising)?

Hi Harry Cayne i placed one ball head at a time in a hand drill and used grit 1200 sandpaper to remove the old chrome. Then i polished it with two kinds of wax based polish. That was it. It really works well still after lots and lots of printing. I also use a small amount of teflon grease on the heads.

ah ok thanks, so you made a nice polishing there no electroplating involved

by the way what software are you using ?

for 3D printing ?

I mainly use Kisslicer and Slic3r, but I have started using CraftWare again and it really works very well. Kiss is very allround and works well. Slic3r is very good for making seamless single walled objects like vases etc.

Did you have problems with the ball head finish?

no not yet I'm a brand new user, but I've just realised that Craftware is hungarian and I am hungarian so I would be happy if this would be a useful software for us !

nice to hear that you are using Craftware too

Ha, that is funny. Go Hungary!

這個模型可以不用支撐

支架也有點難差，GAP是不是應該要調大一點比較好？

這個不用支撐也可以印，1.0版時我有印過

填充設的太小，層高0.1是個問題，最大的問題是Z-Lift=0

Good point, this feature would be nice to have.

0.3 mm Looks like ATOM1.0's layers high 0.15mm

Your printer should be able to print very nicely at 0.3 . Something else is wrong. I have been experimenting with 0.4 and 0.5 and they work fine too, all though speed has be reduced correspondenly. I found that 0.3 prints faster and better than 0.5. Th e Atom2.0's ability to melt larger amounts of fillament fast is not very high. This puts a limit on speed in thicker layers. And no it does not help to increase temperatur.

Andre - I am beginning to suspect you are correct. I just printed a part at 0.2 layer thickness and it does not look nearly as good as one I printed a few days ago. I do not understand why this is happening.

I noticed that Kisslicer has the ability t o choose from 2 different Style Models (Small Models and Normal Models) but it is not clear what these mean. I'm going to make a test part that is just a small cylinder and try different settings to see if I can identify why my layers look so rough.

We've actually used two ceramic heating plates before on the hotend and it helped quite a bit for high flow rate situations

Every single type and colour of filament has its own melting and string characteristics. Even a 5 degrees change of temperature can improve the outcome.

The preset kisslicer styles are just preset values of those settings you see, there should be no internal hidden setting or feature that are tied to the presets

Andrew Lee how come you only use one ceramic heating plate now? I cant imagine the price being the issue.

one plate is sufficient for general use

our engineer has added that it uses more power (wiring will have to be carefully done to prevent overheating and overcurrent), PID settings have to be tuned, temperature harder to stabilize.

you could just get a bigger / more powerful heating plate for your use, after all the ATOM is pretty customizable. we've just been using two plates cause it's more convenient
