Steve Martin and Martin Short were in northern Colorado on Friday for a two-hour show filled with comedy and music. Martin and Short are among my favorite comedians. They have been in many movies and television programs such as the Three Amigos and Saturday Night Live. Martin also starred in Father of the Bride, The Jerk, Planes, Trains, and Automobiles, Parenthood, The Pink Panther, and many others.
The evening began with clips from classic movies and SNL skits to warm up the audience at Budweiser Event Center near Loveland. Martin and Short then appeared to a warm applause and launched into hilarious stories about friends, family, celebrities, and themselves. Throughout the evening, the two took many friendly jabs at one another. They had the audience laughing and in tears. I’m glad my wife and I, along with friends, attended the show.
In the coming weeks and months, Martin, 73, and Short, 69, will perform in other parts of the U.S., as well as in Canada and New Zealand. If you like good, live comedy from two of the very best, book an evening with them. You won’t regret it.
3D printing is fascinating and intricate at the same time, and understanding every 3D printing concept can be overwhelming when you are just starting out. Learning the different materials and technologies gets even more complicated with the often complex 3D printing terminology.
You might have asked yourself if SLS is the same as SLA, or if PA is similar to PLA.
Don’t worry, we’ve got you covered! We want to make it easier for you to start 3D printing with this 3D printing vocabulary list: it explains the most common acronyms for 3D printing in just one place. Don’t let the 3D printing jargon get in your way to becoming the next 3D expert.
Additive Manufacturing is frequently used as a synonym of 3D printing. Additive technologies are defined as the process of joining materials to make 3D objects. AM is the opposite to subtractive manufacturing technologies, which remove material to form an object.
You don’t have to learn its complicated name by heart to become a 3D printing master. But you do have to know that ABS is a plastic from the thermoplastic polymers family. This material, in the form of a filament, is used on FDM printers that heat it up until it melts to create the desired models.
What is an FDM printer, you ask? Keep reading to know more about this 3D printing technology.
This term describes all the design software used in the process of creating, modifying, analyzing or optimizing a design. CAD programs are used by engineers and 3D designers to create and modify the models they want to 3D print. You can learn more about CAD software for 3D printing on this article.
DMLS – Direct Metal Laser Sintering
There are different techniques for 3D printing metals. When laser-based 3D printing technologies use powdered metals, we talk about Direct Metal Laser Sintering. The principle here is the same as with SLS: The 3D printing machine distributes a thin layer of metallic powder while a high-powered laser binds the selected parts together. We use DMLS technology to print in aluminum and titanium.
This is a very popular 3D printing technology among starters. FDM machines build the 3D models layer by layer by heating and extruding thermoplastic material filaments such as ABS. This technology was created in 1988 and patented the next year by S.Scott and Lisa Crump, the founders of Stratasys Crump. Until 2009, the term FFF or Fused Filament Fabrication was used to avoid the legally constrained term.
Most home 3D printers use this technology, but you can use FDM industrial 3D printers to create high-quality models and finishes. Read more about FDM technology on our blog.
This term is a synonym of FDM. It was coined by members of the RepRap Project to be used instead of FDM, a concept that was under legal patent restrictions until 2009.
This HP technology for 3D printing is similar to Selective Laser Sintering, but instead of lasers it jets a fusing agent to melt together very fine grains of powder, resulting in a strong but flexible material. MJF is available on i.materialise and is the best option for sturdy polyamide models with detailed surfaces or thinner walls.
Polyamide (SLS) is a fine, white granular powder used on SLS 3D printing technologies. The natural finish for Polyamide feels slightly sandy and granular to the touch but the material allows a wide range of finishes and colors, as well as nearly unlimited freedom of design. That’s why this material, also known as nylon plastic, is the favorite of many 3D artists and designers.
This 3D printing material, sometimes known as biopolymer, is also used in the form of a filament on FDM 3D printing machines. This thermoplastic is made from renewable raw materials such as plants, e.g. sugarcane, soya, corn or potatoes, and it can have a sweet smell when burned. PLA is a very popular material for home printers because it’s easy to use and cost-efficient, but it’s more brittle than ABS.
SL or SLA stands for Stereolithography, a 3D printing process that uses liquid resins. Stereolithography is used on big printers, like our Mammoth machines, which can print models of up to 2.1 meters. This process takes place in large tanks where a layer of liquid polymer is spread over a platform. Some areas are hardened by a UV laser to become the layers which make up the 3D-printed model. One layer of liquid is spread on top of another until the model is complete and the excess liquid flows away. Watch this video to see Stereolithography in action.
Selective Laser Sintering is a 3D printing technology based on powder. The printer is heated up until below the melting point and a fine layer of powder is spread. After that, a laser beam heats up the parts that need to be sintered together above the melting point. The powder particles reached by the laser are fused together while the rest remains loose powder.
The main advantage of this technology is that no supporting structure is needed, so it allows very complex designs and even interlocking and moving parts.
STL is the name of a very common 3D printing file format. The files generated by CAD programs usually have the extension .STL. It’s supported by most 3D design and printing software, and is probably the most common file format used for 3D printing. Where the word comes from remains confusing: while it’s commonly seen as an abbreviation of STereoLithography, sometimes it is also thought to be an acronym for “Standard Triangle Language” or “Standard Tessellation Language”.
TPU – Thermoplastic Polyurethane
Our rubber-like prints are made with a material called TPU 92A-1. The complete technical name comes from the combination of the acronym for Thermoplastic Polyurethane, followed by Shore A 92, a standard measurement that indicates how soft materials are. The final models are strong but highly flexible.
We hope that this introduction to 3D printing terminology will help you understand how 3D printing technologies and materials work. Learning about 3D printing is like a long-distance race, so don’t expect to understand all the concepts at once and don’t give up when it gets confusing. You can find a lot of inspiration and information about 3D printing on our blog and website.
Luckily, our online 3D printing platform is easier to understand for beginners than the 3D concepts! So, once you know which technology and material are the best for your model, you can easily upload your file to our online 3D printing platform.

With Laser Cut Templates, Drafting And Wireframing Become Faster And More Accurate
We may live in a digital world, but when it comes to brainstorming ideas and retaining what we’ve learned, there are no better tools than taking pen to paper. There’s something magical about how thoughts manifested in the brain seemingly travel down the arm to the hand and out the end of a pen, pencil or crayon (we won’t judge; just let us use the periwinkle one).

If you truly love making things, then you also love making things in the best way possible to achieve desired results. This inherently means learning new methods, studying them, and becoming proficient in them. In turn, making things not just a better way – but the BEST way.
Two years ago, Stratasys entered into a partnership with Boom Supersonic – the Colorado-based company building what’s expected to be history’s fastest supersonic airliner. Their XB-1 is planning to hit the skies in mid-2020.
I have had the privilege of watching with amazement as Boom incorporated Fused Deposition Modeling (FDM) into the normal everyday toolkit. Boom has done this faster than any other aerospace company I’ve worked with. You could argue they’re a small company and agile when incorporating new technology, a luxury many companies don’t have. But this is not it.
Boom was founded on the principle of making something better. It’s not to be innovative, it’s not to be rule-breakers or pioneers – it’s to take a collection of all the better ways of manufacturing and putting them together to build the best supersonic commercial transport aircraft.
Signing a seven-year production-focused extension with Boom is a compliment to Stratasys that cannot go unnoticed. The design and manufacturing teams are not experimenting, they are building. The entire Stratasys team supporting this partnership is beyond excited to work with Boom on upcoming technical development projects – all of which focus on putting the proven Stratasys F900 AIS to work.
So, what’s different about how Boom accelerated their use of additive?
First, Boom doesn’t treat FDM as a special project. It is treated as a potential solution – subject to the same considerations as other technologies to meet requirements, cost and schedule. When printing a part is a better way of manufacturing a geometry, it gets 3D printed.
Second, Boom took the time upfront to get comfortable with the technology by pushing it, failing with it, and succeeding with it. They learned additive in action on the production floor, transparent to anyone in their hanger. Boom gave widespread access to use 3D printers and demanded teams work smarter; and if that meant using the Stratasys F370 or F450 3D Printers to get something done, then they did it.
Third, they’re staying focused on the primary goal – finding and focusing on all the ways to manufacture a better aircraft.
What is your organization’s goal? If you’re struggling to get additive incorporated, my advice would be to stop focusing on additive and start focusing on doings things better.
Spend some time getting educated on the capabilities of additive, and then move forward with the best solution.
This process will likely bring you to additive – and to Stratasys…But only when it’s appropriate to do so.

London-based jewelry brand Maria Piana strives to create a new form of abstract jewelry, using intricate industrial processes and artisan experimental techniques. 3D modeling has become the backbone of creating their design aesthetic and bringing their unique visions to life, elevating their collections in ways not possible before. One of the co-designers at Maria Piana, Constantino Papaconstantinou, walked us through the brand’s creative and technical processes to design and create 3D printed jewelry.
When Constantino Papaconstantinou’s and jewelry designer Maria Piana’s paths crossed for the first time, it was a charmed chance meeting. As a design team, their pieces evoke a sense of sophistication and luxury, with detailed and unique sculpturing made possible by 3D design.
3D-printed ring by Maria PianaPrior to joining forces, both had been working in jewelry for quite some time. Constantino has been in the industry for more than 20 years, working with international retail brands and then starting his own jewelry design company and lab. Maria Piana began her career as a dentist before pursuing her passion for jewelry and starting her namesake London-based brand. When they met, she had been working on her second collection and together Constantino and Maria expanded the Maria Piana brand to elevate the pieces from the statement line to include more wearable pieces.
The brand’s designs have been featured in Vogue and on other international magazine covers, and worn by celebrities such as Beyoncé and Lady Gaga.
Constantino saw the potential of using 3D design to create jewelry back in 2003 when he first started experimenting with 3D software. 3D modeling software to design the jewelry has made it possible to visualize certain pieces and aspects of the jewelry in ways that were not possible before.
“Ever since I was a kid, I have been drawing and designing, from copying maps to sketching floor plans,” he tells us. “When I realized I could design and manufacture the types of pieces I was thinking of by using 3D software, I was fascinated and started learning Rhino.”
This has allowed Constantino to design and print more complex pieces.
“3D design gives you the opportunity to see things before they are constructed or manufactured, make any changes on paper, cut trial and error procedures, and speed up processes while being confident about the final result,” Constantino explains.
Maria Piana’s first collection consisted of waterjet-cut pieces, while the second collection took that next step forward and added a third dimension to the wearable line, to experiment with more complex and playful shapes and designs.
“I have 3D printers, casting machines, and furnaces in my own lab, but they are oriented towards custom gold jewelry. I did some online research I found i.materialise and their parent company Materialise, and because I trusted the results I saw in their portfolios, I proposed to Maria to take a shot with our first 3D printed pieces,” he says.
They have been using the i.materialise platform ever since.
“The quality and polishing of i.materialise is excellent, and overall I must say that it’s great value for money and it has saved me a lot of time trying to produce these large and complex pieces myself,” he says. He is able to simply upload the design to the i.materialise website, wait for the order to arrive and then add small final touches where needed (such as earring clasps).
As a dual team of collaborative designers with a passion for exploring new ways of designs, working with i.materialise and using 3D printing has been the ideal creative scenario. From a business standpoint, using 3D printing is also more economical, since the brand are looking to drop small collections of complex designs in brass or silver, and in small to medium quantities where economies of scale cannot be applied. To build the design, they use lost-wax casting as the technology which captures all the intricate and precise details of the pieces, making it ideal for 3D printed jewelry.
From a paper concept to a printed reality
Maria and Constantino start designing their collections using a mood board, with a selection of around 20 pieces per collection. Constantino then begins designing the 3D models. This is mostly done using Rhino, occasionally using other software to add some texture where necessary.
“I use a completely stripped-down version of Rhino with no add-ons or libraries because I like using parts designed by myself and skip the ready-made components in libraries,” he says of his work process. “This definitely adds to the identity of the design, makes it more difficult to copy, and in the end, makes you a more skilled 3D designer since you have to figure out custom solutions instead of resorting to cookie-cutter ones.”
Designs are then printed in brass to be showcased in exhibitions (Premiere Classe in Paris Fashion Week, during London Fashion Week, HOMI Milano) and then reprinted in brass or silver depending on orders. The finish the brand opts for brass is usually gold plating on a highly polished surface.
However, designing intricate pieces of jewelry isn’t without its challenges, Constantino explains.
“Sometimes we would like to add more information to the design, to make it more complex, to give it more layers, so to speak,” he tells us. “The change in mindset is the most important and realistic approach that they have to use when they are designing the pieces in 3D, whereas on paper, they can still be dreaming.”
“After all, when you design in 3D software, you are not only designing but you are simultaneously modeling,” he explained. “This means you are in a way constructing, so there must be a sweet spot between aesthetics and the ability to produce the actual design, a spot where the idea, purified by the filter of production methods we have in mind, becomes the final product design.”

Angel Trains, DB ESG, Stratasys and Printing Portal have just received “Highly Commended” recognition for a third-place finish out of 20 entries at the annual Railway Industry Innovation Awards, held in London on 28 June.
The collaboration builds on additive manufacturing to address the issue of obsolete parts, reduce whole life rolling stock costs and enable vehicles to remain in passenger service longer. This innovation also has the added potential to lower costs for train operating companies, as smaller volumes of parts can now be produced cost-effectively, rather than in mass quantities.
The group has established a process enabling production of components that comply with rail industry standards and are suitable for use in passenger vehicles. The group leverages Stratasys’ Fused Deposition Modelling (FDM) additive manufacturing technology and have several successes since the collaboration began less than a year ago. These include:
The partners have also agreed to a range of R&D work to further push technology boundaries and speed adoption by the wider industry.
Some comments from our partners:
“This is the beginning of an exciting future in the 3D printing area. AM offers far greater control of the supply chain and has the potential to radically transform the rail manufacturing industry. As one of the largest investors in UK rail, we continue to work hard to ensure that our innovative technology drives industry advances and revolutionises passenger experience. We are collaborating with transport companies from across Europe to help drive this technology and strongly support operators and suppliers in adopting this technology on Angel Trains’ assets.” –Euan Smith, Head of Product Management, Angel Trains
“This has been an exciting project to work on to date. Our role has been in investigating the design, production and finishing of FDM parts, verifying whether the parts comply with rail standards and checking whether they work in the operating environments. We have also optimised the component design of FDM manufacture.” –Martin Stevens, Head of Mechanical Engineering, DB ESG
Founded in 1998, the Railway Industry Innovation Awards is the longest-standing awards scheme in the industry. Organised by the 4th Friday Club, these annual awards celebrate the brightest ideas in the market.
We truly believe this is just the beginning – and together with our partners – we will drive the widespread adoption of 3D printed parts across the rail landscape.

The Expanded Acrylic Selection Gives You More Laser Cutting Options
We love getting feedback on all the designs you’re laser cutting. One request has been more thickness options for acrylic. “Ask, and it shall be given to you!”
Previously only available in 3.0mm thickness, now matte black acrylic has been added to the NZ catalog in 6.0mm thickness and to the USA catalog in 5.6mm thickness. And as an extra bonus for those stateside,
