From growing up in the German countryside to living in China, Noah Hähnel’s inspiring story is the focus of today’s blog post. This young designer will explain the highlights of his experience with 3D printing and will give some tips for 3D-printed jewelry beginners.
Ever since I was a little kid, I loved to create and early on I discovered my passion for films. Through films, I also got interested in visual effects and that made me want to learn 3D modeling. With 3D modeling, I discovered 3D printing, which gave me the opportunity to turn my ideas into something physical you can hold and feel.
My first ever design for jewelry was a simple pendant with two arcs in it that I made as a present for a relative and printed it in stainless steel. She loved it and friends of her asked me to do more. Like every designer, I live for approval and attention.
In 2013, when I was just 14, I tried my luck at a competition by i.materialise where you had to design a traditional Japanese hair piece. I made it to the 10 best designs and the piece was shown in Tokyo. That’s when I got the idea to sell jewelry.
Even though my passion still lies in filmmaking and becoming a director, I continue to create jewelry that can be worn by a broad audience. I can put my ideas and stories inside them, just like with movies.
This collection consists out of five new designs and it was inspired by an idea for a short film, about a mystical part of a forest that never has been touched by mankind. One ring, for instance, is made of vines that grow around your body.
Also, I am in love with nature. I grew up in a rural area in Germany. We had horses, cats and dogs, and we are surrounded by cows and forest. That is why I often use nature in my designs.
My workflow is mostly spontaneous. I do not tell myself: “I need to get new designs every week”. I
design when I feel inspired, or someone asks me for a piece. Sometimes I draw the basic model on paper, even though I can’t draw at all, but as long as I can see what it’s supposed to be it is fine. But most of the time I just start on my computer with an idea and see how it develops.
For example, the idea for the Garden Ring came from a short film idea of mine. I first started by designing vines and several flowers. After that, I thought about where to use it. I often design something first and then see what kind of jewelry it should be used on.
After I have finished designing, and have exported and double-checked that no triangle is missing and no sizes were changed during the export process, I finally hit “Order”.

That is why I often use nature in my designs.
I design with Cinema 4D. I started using it when I was twelve. Later I noticed that many German companies I was a trainee for used it too, which was helpful. I think it is a really powerful and user-friendly program that developed from a pure motion graphics tool into an all-rounder, with a focus on modeling, sculpting, animation and visual effects.
My go-to material is bronze. The wax 3D printing allows for incredible small details and cheap prices. Bronze is beautiful, durable and can be changed with acids. It is also not likely to cause allergies and is affordable for most people. All of this adds to the fact that bronze looks a lot like gold, which is my favorite color.
Bronze and gold have been used since ancient times and combining these with a modern technology such as 3D printing feels and looks amazing. One of my philosophies is to make something that cannot be achieved with traditional methods. I often see designs that are beautiful but very “simple” and I ask myself: why not use the full capabilities of 3D printing technology?
Bronze and gold are used since ancient times and combining these with modern 3D printing feels and looks amazing.
The greatest challenge for me is the export of my designs. Sometimes it takes me days to clean up a design so no triangles or walls glitch and disappear. While modeling, I do not really care about technical stuff so the exported models are as messy as my desk or thoughts.
I try to keep my files as editable as possible. When I started out, I finished with one completely merged object which was easier to export, but difficult to make alterations on after completion, like changing wall thickness, or the size of certain details.
As an example, the flowers of the Garden Ring might be printable now, but if I scale down the whole model to a smaller size they might become too small to print. So I only scale down the vines to achieve a smaller ring size.
This technique also allows me to only change small details for each customer and thereby make the object a little more unique. Furthermore, I can increase the ring size without increasing the bounding box, which allows for cheaper prints.
While modeling I do not really care about technical stuff so the exported models are as messy as my desk or thoughts.
Another important thing I have learned when I design jewelry for 3D printing is to always keep in mind what material you are designing for. With bronze, you can achieve everything from matte brown to shiny gold. That depends on how you design the highs and lows and how even the surface is.
The vines of the ring are a great example. Even though the indentation between the vines is only around 0.8mm deep it looks a lot deeper because it has a darker shade that you can’t polish. A rough surface always looks more detailed than a plain one.
Once I receive the printed models I take pictures. Often by myself but this time I got help from filmmaker Sören Schulz. We built a softbox out of diffusion gels. We used two different kinds of surfaces to place the jewelry on: a classic white one but also a black reflective glass.
After the photo shoot, the pictures were edited in Photoshop. We shot the pictures in RAW because it’s always nice to have the extra information, like better dynamic range. This time we are also planning to shoot a little commercial video.

The TCT Show has always been an inspiring event for additive manufacturing designers and engineering innovators. Many of the attendees come to the show to meet and mingle with some of the region’s best and brightest in the 3D printing space, to share creative ideas and use cases and discover trade secrets they’ve learned through practicing their craft.
One of the ways that we are excited to support this collaborative exchange is by hosting an Application Challenge at our booth during this year’s TCT Show. The challenge brings unique and interesting perspective into focus around the way that companies are thinking about 3D printing inside their businesses. Matt Johnson, Technical Consultant with Stratasys for the UK and Northeastern Europe regions, as well as a designated consultant team member for the Application Challenge, noted that the challenge is one aspect of the show he is especially looking forward to. “It’s interesting to see what people are doing with 3D printing.” He noted “A jig or fixture to one company looks completely different to another.”
Lending a bit of suspense and surprise to the already packed agenda, the Application Challenge is an opportunity for firms that are considering the implementation of additive design or 3D printing business solutions, or for those who have already developed processes, perhaps for prototyping, to discuss the gaps or challenges they might face as they move toward maturing additive in their businesses. “The theme of this year’s show, accelerating 3D technologies, has to do with the way that customers use 3D printing in everyday applications. As the industry evolves, consumers are becoming a lot more savvy, and spending more time looking into how specific applications can make sense for their business. Advanced prototyping, jigs and fixtures and composite layup tooling are becoming more common in manufacturing environments, evolving 3D printing from the previously held position of just prototyping.”

This week is Prostate Cancer Awareness Week! Did you know that prostate cancer is the most common cancer among men in the United States? In Cancer Statistics 2017, scientists from the American Cancer Society estimate that there will be over 161,000 new cases of prostate cancer among men in America this year. Although deaths from prostate cancer have dropped significantly over the past 20 years, an estimated 26,730 American men will die from the disease in 2017 alone.[i] A lot of work remains to be done to reduce this number even further and to raise awareness about the disease.3D printed prostate tumor model showing the prostate (clear), cancer (blue), nerves (yellow), urethra (pink), rectal wall (white) MR image segmentation; Middle, virtual prostate cancer model; Right, 3D printed cancer model. Prostate (clear), cancer (blue), nerves (magenta), bladder neck and urethra (yellow), rectal wall (white).
For my PhD thesis project at the NYU School of Medicine, I am working with a collaborative team of radiologists and urological surgeons to investigate what impact 3D printed multi-colored models of a patient’s prostate cancer on can make on pre-surgical planning and intra-operative guidance. Printed on the Stratasys J750, we are also using the models during patient consultations to see whether they can facilitate patients’ understanding of the disease and of the surgical treatment. Most patients don’t know how to interpret radiological images, but may better understand the anatomy, disease, and surgical plan by handling 3D models and discussing the models with their doctors.
In order to create these patient-specific 3D printed models, the prostate is segmented from multi-parametric magnetic resonance imaging (MRI) studies and converted to a 3D virtual model.
It is our hope that 3D printed prostate cancer models help to improve surgical outcomes and patient understanding of disease. We also hope to increase public awareness of prostate cancer. Click here to learn more about my research and 3D printing at NYU.

For many organizations, additive manufacturing (AM) remains relatively new to their portfolio of process solutions. And although AM has been around for awhile now, most enterprises are now realizing the potential benefits of additive beyond prototyping. The TCT Show, in Birmingham, UK kicks off September 26, 2017, and this year’s program features the best and brightest minds centered around pushing the boundaries of what’s possible in AM, and moving the industry forward in innovative and unique ways.
We will be there collaborating with some of our partners, like McLaren Honda, whose car will be featured at our exhibition booth. We will have technical consultants ready to help answer your additive manufacturing questions at the Application Challenge, and we will also have a speaker, Amos Breyfogle, on the product stage discussing Tooling Up: The 3D Printing/Additive Manufacturing Opportunity Beyond the Design Process and into Production. I was able to talk little with Amos about the upcoming show, and some of the tangible impacts of additive manufacturing that will be on display. Here are some insights he shared with me about what to expect from Additive Manufacturing as an industry.
Although its roots lay in design validation/prototyping, advances in additive manufacturing have seen the technology continue to strengthen its foothold across a plethora of applications throughout the manufacturing chain. For those supplying industry sectors like aerospace and automotive – as well as a host of others – the adoption of additive manufacturing over traditional production methods can significantly reduce lead times and cost, with the potential to have a transformational impact on supply chains.
From composite tooling to jigs & fixtures, this year’s presentation will go beyond 3D printing’s design-stage heritage and focus on the business opportunity when implementing additive manufacturing across a variety of production-line tooling applications.
Additive Manufacturing is increasingly finding a home along side traditional manufacturing processes. For instance, composite tooling is an area where many companies are moving to additive solutions for the challenging geometries. They can save time in production, weight on the tool itself, and in the end, cost.
We see a large adoption happening around using other types of tools as well, from jigs and fixtures for assembly, to automation systems to help operators be more effective.
As we come to the close of 2017 we are seeing more and more customized production happening. This has been going on in very high end automotive and aerospace in the past few years, the difference is we are starting to see this be adapted to larger production volumes and lower cost products. When we combine that with the ever growing number of people using additive tooling, it makes this industry an exciting place to be working.

We often get asked this question: “What is the best 3D modeling software?” The ugly truth is, “It depends.” We can’t tell you which software you should use. But we can tell you how to find it!
Think about it in terms of the world of traditional 2D printing: What’s the best software for 2D printing? It’s impossible to answer this since someone might want to print a text, somebody else might want to draw something, while yet another person might want to edit a photo.
For 3D modeling software it’s a bit like that. There’s not one software that dominates the market and is most suitable for everyone. Every designers has different needs, preferences, and objects in mind. That’s why it’s simply impossible to say “This is the best 3D modeling software for everyone”.
However, we have put down certain questions that you can ask yourself, which will help you find the software that suits you best. In the first part of this article we will present the decisions you need to take. In the second part we will show you how to find the best software based on these decisions.
The first decision that you need to make is what kind of objects you have in mind. The choice of what you want to design often determines which modeling software you should use.
Not every software package or app is available on each platform. Think about which platform you will be using for creating your designs.
Software can be free or cost thousands of dollars. The amount of money you are willing to spend on 3D modeling software facilitates the choice.
Some software programs have been around for years and have big communities behind them. There are tons of tutorials and active forums to be found. Others have just started or are trying to bring their product to market. So the size of the community and number of software-related resources might also be an important factor. For beginners it might be easier to stick to software that has been out for years and offers tons of resources and YouTube tutorials. When you get stuck somewhere, it also means that you will be able to find help from fellow designers more easily.

Another thing to consider is the purpose of the software. Some software was developed for visual 3D effects or 3D animation films. The 3D printing part is more like a ‘side product’ for these programs and it needs a bit of tinkering to turn a great visual 3D model into a model that is actually 3D printable. Others were developed especially for 3D printing and will make it much easier for you to ensure that your design will be printable.
So it’s important to check if there are enough resources, tutorials, and forums that are not just about “3D modeling with software XY”, but also about “3D printing with software XY”.
For many beginners this is an important one: the interface. Some software provide you with an interface like a car dashboard: clean, easy to learn and intuitive. Others go for an aircraft’s cockpit: lots of functionality, much more design freedom, but a steep learning curve.
An example for this can be found in the pictures below: Both Tinkercad (left) and Blender (right) are available for free. Tinkercad has an intuitive, beginner-friendly interface. However, your design freedom is somehow limited. Blender, on the other hand, offers lots of functionality and design freedom but might be harder to learn.
Different software uses different approaches to 3D modeling. It is hard to categorize an abstract thing like “modeling” into different techniques, and it can be difficult to get an understanding of it when you haven’t used the software yet. However, we will still try to give you an overview about the most important distinctions. We included a short visual preview for each of these 3D modeling techniques. Which technique is best for you heavily depends on your preferences. While some prefer a LEGO-like modeling approach, others prefer clay-like sculpting.
Solid Modeling/Box Modeling: Solid Modeling is all about combining and subtracting primitives. If you like(d) playing with LEGO you will find this way of modeling quite intuitive. You will add cubes, spheres and all kinds of other geometrical objects and combine them or subtract them from each other. The catchwords for solid modeling are accuracy, precision, and exactness. However, this comes with a price: limited freedom in designing. It will be tough to create organic objects with this kind of modeling.
Digital Sculpting: Digital sculpting presents quite a big contrast to solid modeling. Typically you start with a digital cube of clay and form it with your mouse. It also is very intuitive as clicking on the object will immediately deform it. Typically you can select a tool (like push, pull, smooth, grab or pinch) and then start sculpting. This way of modeling gives modelers an extreme freedom of design, but it is not precise. It’s great for organic models (like people, animals, etc.) but it’s virtually impossible to create functional parts with it.
Parametric Design/Procedural Modeling: Parametric design is based on algorithmic thinking and actually lets you ‘program’ objects. This might be by really scripting code, but there are also ways to make this more visual. Nevertheless, you will typically have two screens: an editor, where you will input functions or commands, and a preview of your design. This two-window-setting might be less intuitive for beginners. However, it allows for users to play around and create generative artwork as well as precise mechanical parts. Changing patterns and repetitions is often just a matter of clicks.
Polygon Modeling/Contour Modeling: In Polygon Modeling, your 3D object is basically a mesh based on vertices, edges and faces. This allows you to easily and precisely edit parts of your object. By changing the coordinates of one or several vertices, you can change the shape of the model. The downside, however, is that it is not possible to describe a curved surface accurately. Since there is always a straight edge between two coordinate points (vertices), rounding objects is difficult.
Curve and Line Modeling: In contrast to Polygon Modeling, surfaces in Curve Modeling are made up of curves. Curves are created with a tool that works very similarly to the pen tool in MS paint or Adobe Illustrator. The curve is drawn in 3D space, and edited by moving a series of handles called CVs (control vertices). Alternately, a curved surface can be created by revolving a profile curve around a central axis. This is a common and very fast modeling technique for objects that are radial in nature. This is why this modeling approach is very popular when creating automotive and industrial parts.
Okay, this has been a long list but what are you supposed to do now? It’s time to put the pieces of the puzzle together.
First of all, it is helpful to get a general overview of different programs and their target audiences. One way to do so, is by visiting the ‘3D Design Tools’ section of our website (see screenshot below). This page will give you an overview of popular 3D modeling programs for 3D printing. It lets you filter for price (free, freemium, premium), platform (PC, Max, Linux, etc.) and the most common use (Art, Architecture, Spare Parts, Jewelry etc.). What’s more: you can see actual 3D prints that were designed with that specific software. Often these images say more than a thousand words.
Apart from visiting our 3D Design Tools overview, you should also take a look at the following resources and rankings:
Once you’ve narrowed down several programs that you would like to give a try, take a good look around their websites. Do the models that were designed there come close to your needs? A website visit can often give you a glimpse of what the program is actually being used for – and what it isn’t. Before you buy a pig in a poke, make sure to download a free trial version and give it a try. Literally every 3D design software comes with a free trial version nowadays.
If you’re new to the world of 3D modeling, this interview about how to get started with 3D modeling might be useful. If you already have a printable 3D file, simply upload it to our website, choose from more than 100 material options, and let us take care of printing and shipping your object.
I’ll be hosting a thought provoking discussion on the future of design, autonomous systems & artificial intelligence @ my studio on the evening of the 20th September 6:30-7:30pm.
