Paramatric Model Maker V0.9.0 - Support Multi-Color Modeling

中文版本在下方。

English Version

We’re thrilled to announce that Parametric Model Maker V0.9.0 now supports multi-color model export! This exciting feature was made possible thanks to the valuable contributions of our amazing community (GitHub - ochafik/openscad at color-assimp2). Leveraging the latest OpenSCAD update, which allows color information to be exported with 3D models, Parametric Model Maker can now export vibrant, multi-color models in the 3MF format.

Creating Colorful Models

Parametric Model Maker makes creating multi-color models intuitive by using OpenSCAD’s familiar syntax for defining colors within your script:

color([1,0,0]) cube([2,3,4]);     // Red. Defined as an array with values in the 0~1 range
translate([3,0,0])
color("#00FF00") cube([2,3,4]);   // Green. Defined as a hex string
translate([6,0,0])
color("blue") cube([2,3,4]);      // Blue. Defined as a web color name string

For a deeper dive into OpenSCAD’s color functionalities, check out their documentation: OpenSCAD User Manual/First Steps/Changing the color of an object - Wikibooks, open books for an open world

Making Color a Parameter

Want to give your users the power to customize their creations? You can easily turn colors into adjustable parameters within your models. Here’s how:

  1. Define your color in hex format as a string variable.

  2. Add the comment // color at the end of the variable declaration. This signals to Parametric Model Maker that this variable represents a color parameter.

// Color for the first cube
color1="#FF0000"; // color
// Color for the second cube
color2="#00FF00"; // color
// Color for the third cube
color3="#0000FF"; // color

color(color1) cube([2,3,4]);
translate([3,0,0])
color(color2) cube([2,3,4]);
translate([6,0,0])
color(color3) cube([2,3,4]);

Important Note: When defining a color as a parameter, only the hex string format is supported.

参数化模型编辑器 V0.9.0: 新增多色模型支持

我们很高兴地宣布,参数化模型编辑器 V0.9.0 现在支持多色模型导出! 此功能归功于OpenSCAD 社区的宝贵贡献(https://github.com/ochafik/openscad/tree/color-assimp2)。利用最新的 OpenSCAD 更新(允许将颜色信息导出到 3D 模型),参数化模型编辑器现在可以导出多彩的 3MF 格式模型。

创建彩色模型

参数化模型编辑器通过使用 OpenSCAD 定义颜色语法的熟悉方式,使创建多色模型变得直观:

color([1,0,0]) cube([2,3,4]);     // 红色。以 0~1 范围内的数组表达颜色
translate([3,0,0])
color("#00FF00") cube([2,3,4]);   // 绿色。以十六进制字符串表达颜色
translate([6,0,0])
color("blue") cube([2,3,4]);      // 蓝色。以颜色名称字符串表达颜色

有关 OpenSCAD 颜色功能的更深入了解,请查看其文档:OpenSCAD User Manual/First Steps/Changing the color of an object - Wikibooks, open books for an open world

将颜色设为参数

希望让用户能够自定义颜色吗? 你可以轻松地将颜色转换为模型中的可调参数。 操作方法如下:

  1. 以十六进制格式将颜色定义为字符串变量(例子:#FFFFFF)。

  2. 在变量声明的末尾添加注释 // color 这向参数化模型编辑器表明此变量表示颜色参数。

// 第一个立方体的颜色
color1="#FF0000"; // color
// 第二个立方体的颜色
color2="#00FF00"; // color
// 第三个立方体的颜色
color3="#0000FF"; // color
color(color1) cube([2,3,4]);
translate([3,0,0])
color(color2) cube([2,3,4]);
translate([6,0,0])
color(color3) cube([2,3,4]);

**重要提示:**将颜色定义为参数时,仅支持十六进制字符串格式。

Awesome!!! I have been waiting for this option sooo long.
After work I will start updating all my designs with this new feature, but first tests have worked great

Wow, this is a feature I’ve been waiting for forever! Huge shoutout to Olivier for getting this implemented. I don’t think it has even made it to the latest development build of OpenSCAD since it’s still on the color-assimp2 branch. Major props to the Bambu team for staying on top of these updates and making it available so quickly! This is going to be awesome!!

I would like to express my gratitude to Bambulab for referencing my model!
This provided me with the incentive to make adjustments to the .scad file, specifically enabling users to customize the color scheme of the QR code, the background, and the labels.

Now, check all your existing uploads because you will have left some colour declarations in your code without thinking it would be included that may render as such where it wasn’t intended.

It hasn’t been included in the main development, there are two “implementations” that have significant side-effects. If this manages it without those and flawlessly, superb.

You can say a lot about MW and BL and how they fail to listen and make daft designs, but, the team doing this project nailed it! They should be applauded for the whole parametric solution.

I just wish this level of listening to customers and creators alike would happen for all vital requests that have enough users behind it.
Don’t use parametric model makes as I can’t be bothered learning new tricks I have no real use for.
But even I see the benefits here.
Still try to keep my hopes up that one day Bambu will implement a properly capable, easy to use modelling option right into Studio.
Maybe not on par with Fusion360 in terms of engineering options or timeline based modifications.
Probably not any free forming, sandboxing or such options like Blender and such offer…
A nice and above child level modelling option though would clearly make a difference to many newbies in the 3D printing world…

Keep it Bambu, this one shall not be a one off to impress us :wink:

Bambu Studio offers a lot of flexibility with its built-in primitives for modeling. While it’s not full 3D sculpting, you can still do quite a bit—add negative parts, move objects along any axis, and rotate them as needed. Plus, there are various cutting features, like splitting objects with snaps and slides. There’s plenty to explore without needing to switch to another app!

Basically parametric models are the reasson I’m uploading designs to makerworld.
For me it is the perfect mix between my designing skills and programming skills (the way I make a leaving).
Most of my designs are working pretty good, and during the last 4 or 5 months I have reached about 700/800 euros in gift cards thanks to this designs so no complain at all.

@PineappleBun_BBL I have already migrated some of my desings to start using the colouring function, and it is working great.
Ii is even helping me simplify some options, as now I don’t need to use a “preview” mode to show some pieces that were hard to see in just one colour.
For now I’ve migrated this:

I will continue tomorrow and the weekend with the rest of the designs.

Thanks a lot and feel free to contact me if you need any beta tester for future updates

I’m trying out the Multi-Color modeling and it seems to generate the model fine with all the coloring but when I go to download the 3mf file, it thinks for a while and then I get the message “Failed to download 3mf file”. Is there any way to get more information about what is causing it to fail? I can download the STL without problem.

I could be too large and it cannot fit in a plate. Please try to resize it.

I was eventually able to fix it but the download to 3mf definitely needs some better error messages. I think it had something to do with overlapping geometries.

Are you planning to allow generating bigger models?
I’m working in a script that needs to generate 2 parts, that individualy will not be bigger than the build plate, but both at the same time could not fit.
Also an option for exporting the models in two plates would be great.
