所见即所得的实时3D打印技术

On-the-Fly 3D Printing While Modeling | Two Minute Papers

亲爱的学霸们大家好 这里是由Károly Zsolnai-Fehér带来的两分钟论文
Dear Fellow Scholars, this is Two Minute Papers with Károly Zsolnai-Fehér.
你一定会爱上我们这回讲的这篇杀手级的论文的
You are going to love this killer paper.
在三维制造的经典场景里 我们总是先在建模软件里创建一个
In the classical case of 3D fabrication, we first create a 3D geometry in our modeling
三维模型
software on a computer.
然后 在建模完成后 把它发给3D打印机去打印一个真实的物理
Then, after we’re done, we send this model to a 3D printer to create a physical copy
拷贝
of it.
如果我们对打印出来的模型的某一方面不满意 我们就必须回到电脑前
If we don’t like an aspect of the printed model, we have to go back to the computer
对模型进行相应的调整
and adjust accordingly.
如果还有更多的根本性的问题 我们可能还得返工重做
If there are more fundamental issues, we may even have to start over.
注意 有了我们今天讲的这篇论文 我们就能获得一个低精度的线框版模型
And get this, with this piece of work, we can have a low-fidelity wireframe version
在建模的同时立即将其打印出来
printed immediately as we make changes within the modeling software.
我们可以把这个过程称作 实时的 或 所见即所得的 3D打印
This process we can refer to as real-time or on-the-fly 3D printing.
这篇文章中详细阐述了硬件设计和3D打印机所运行的算法
In this work, both the hardware design and the algorithm that runs the printer is described.
该方法有很多优势 当然 也有很多挑战性的问题需要处理
This approach has a number of benefits, and of course, a huge set of challenges.
比如 我们可以直接看到我们不同决策的结果 还可以测试一个新的
For instance, we can immediately see the result of our decisions, and can test whether a new
设备是不是准确适用于我们的设计场景中
piece of equipment would correctly fit into the scene we’re designing.
有时候 根据最终模型的几何形状 不同的任务需要重新规划
Sometimes, depending on the geometry of the final object, different jobs need to be reordered
以做到物理上可打印
to get a plan that is physically plausible to print.
在这个例子中 艺术家先设计了底部分支 然后才是顶部分支
In this example, the bottom branch was designed by the artist first, and the top branch afterwards,
但是打印顺序必须做出相应调整 不然底部分支会挡住喷头
but their order has to be changed, otherwise the bottom branch would block the way to the
打印顶部分支的路径
top branch.
文中的算法能够识别这些情形并且重新规划打印顺序以使打印任务能够顺利完成
The algorithm recognizes these cases and reorders the printing jobs correctly.
相当靠谱
Quite remarkable.
而且 另一种解决方案 即通过旋转模型获得的可打印范围
And, an alternative solution for rotating the object around for better reachability
也在本视频中有所演示
is also demonstrated.
因为事实上这个算法能够处理这种决策问题 我们
Because of the fact that the algorithm is capable of this sort of decisionmaking, we
甚至不需要等待3D打印机完成当前步骤就可以做下一步的设计 这样也能使一直专注于
don’t even need to wait for the printer to finish a given step, and can remain focused
模型设计本身
on the modeling process.
此外 像这里茶壶的把手处和茶壶杯体相交了 因为线框建模的局限性
Also, the handle of the teapot here collides with the body – because of the limitations
这种情形必须被检测出来而且去掉
of wireframe modeling, such cases have to be detected and omitted.
给模型连接不同的片和添加不同大小的洞状结构同样是非常不简单的
Connecting patches and adding differently sized holes to a model are also highly nontrivial
问题 这些也都在文中有所阐释
problems that are all addressed in the paper.
此外 这篇工作也展现了软硬件
And this piece of work is also a testament to the potential of solutions where hardware
交叉设计的潜力
and software is designed with each other in mind.
我能够想象作者花了多少时间在这个项目上 直到最后找到
I can only imagine how many work hours were put in this project until the final, working
可行的解决方案
solution was obtained.
着实是了不起的工作
Incredible work indeed.
我们在这里只是粗略介绍了一下这篇工作的皮毛 你一定要看看视频介绍里
We really just scratched the surface in this episode, make sure to go to the video description
附的原文 可以获得更多的实现细节
and have a look at the paper for more details.
它真的很值得一读
It’s definitely worth it.
