From fabricating radical new sneaker designs to manufacturing incredibly light prosthetic limbs, 3D printing is generating exciting new products and new jobs with the click of a button. 3D printing is a multi-billion dollar business that’s revolutionizing the world around us.

HV3D evolved out of a desire to release the technology from being trapped or hidden within the confines of one classroom or by one professor. The initiative was designed to accelerate the use of the technology by both concentrating heavily on ensuring access to the equipment and technical expertise by a wide range of potential users and focusing greater attention on elevating technical knowledge of the practical application of the technology (new product development, parts produced, models created, etc.) This shift away from concentrating solely on research and development, and moving toward building a vast, rich knowledge base feeds both the growth of today’s (and future) STEaM workforce needs and allows for easier access to the technology itself (and expertise on applying the technology) by business owners.

HV3D brings together a community of 3D printing experts, private and public investors, academics and entrepreneurs to democratize the technology and knowledge surrounding digital design and fabrication; thereby, unleashing the full potential of this technology for the benefit of the Hudson Valley. HVEDC selected SUNY New Paltz as the “home” for HV3D, because the college was the perfect fusion of an interdisciplinary approach to the technology between the fine arts and science and engineering, which goes right to the heart of understanding how to best employ 3D printing technology.

HV3D established the Hudson Valley Center for Advanced Manufacturing at SUNY New Paltz, which led to the creation of the nation’s first MakerBot Innovation Center and the upcoming establishment of an Engineering Innovation Hub. In 2015, HVEDC was awarded a Business Facilities Economic Development Award for spearheading the development of HV3D in the magazine’s Achievement in Innovation Hubs category. Also in 2015, HV3D was selected by the International Economic Development Council as a Gold Award Recipient in the category of Regional and Cross-Border Collaboration for Population Centers Greater than 500,000.

Hudson Valley initiative brings 3D printing cluster to New York

3D printing—otherwise known as additive manufacturing—is coming to the Hudson Valley in New York in a big way. The Hudson Valley Economic Development Corp. (HVEDC) announced in May that it has embarked on a third, major cluster marketing initiative in addition to the NY BioHud Valley and Hudson Valley Food & Beverage Alliance. The HVEDC expects that the 3D printing initiative will grow to be the largest of the three clusters.

Clare Goldsberry | Jun 21, 2013

HVEDC President and CEO Laurence P. Gottlieb formally launched the organization's new Hudson Valley 3D Printing initiative, which puts together in one place educational and funding resources for Hudson Valley businesses or individuals, wanting 3D printing technology.

"[The] Hudson Valley 3D Printing initiative is bringing together business people with academia and community leadership to rapidly accelerate the growth of one of the most exciting technologies to emerge this century," said Gottlieb at the HVEDC's 'Next Big Thing' breakfast series hosted by SUNY New Paltz.

Ulster County businessman and HVEDC board member Sean Eldridge is spearheading a $1 million dollar investment to create manufacturing jobs and spark economic growth in the Hudson Valley. The initiative will include a $250,000 investment from Eldridge, as well as a three-year matching grant from Central Hudson Gas & Electric (a founding member of HVEDC) to create the Hudson Valley Advanced Manufacturing Center at SUNY New Paltz.

The Center will bring state-of-the-art 3D printing equipment to the region, as well as the expertise and curriculum needed to provide students with hands-on training in this growing industry, as provided by SUNY New Paltz. A new certificate program will be established to help prepare students for jobs that incorporate 3D printing, said the HVEDC in a release.

The impact of the Hudson Valley Advanced Manufacturing Center will extend beyond SUNY New Paltz, as the region's community colleges will have access to the Center for training and use of the equipment, so they can design, test and create new products and manufacturing processes. As the center grows, local businesses will be able to rent the state-of-the-art 3D printing equipment to create prototypes and grow their businesses.

In addition to the Advanced Manufacturing Center, Eldridge is committing up to $500,000 for investments in Hudson Valley companies that incorporate 3D printing in their businesses to help grow this new industry. The investments will be made through Eldridge's Kingston-based investment fund, Hudson River Ventures.

"3D printing has tremendous potential to grow our economy and create jobs in the Hudson Valley," said Eldridge. "There is a great tradition of innovative manufacturing in the Hudson Valley. We have skilled workers, world-class universities, access to the largest markets in the world - and now we will have the equipment, the training and the investment to lead the charge on 3D printing. I want to thank SUNY New Paltz, Central Hudson, and the Hudson Valley Economic Development Corporation for partnering with me on this exciting project to bring this revolutionary technology to our region."

Steven V. Lant, chairman of HVEDC and chairman and CEO of Central Hudson Gas & Electric, said, "Central Hudson Gas & Electric is proud to support the Hudson Valley Advanced Manufacturing Center at SUNY New Paltz with our investment. The new state-of-the-art printing equipment will help provide students with the exciting, new and necessary skills to advance in this growing field, and create opportunities for entrepreneurs to launch or expand their businesses."

Gottlieb added in a prepared statement, "Because of this coordinated effort, students will be challenged and grow in a new, dynamic industry, and entrepreneurs will have a willing business entity with financial resources if they are utilizing 3D technology in their businesses."

Attempts to find out the types of 3D printing the initiative would be offering were unsuccessful, and calls and e-mails to Gottlieb and the PR agency were not returned. However, the group did work with Stratasys Ltd., according to Sharon Smith, vp of marketing for Stratasys, who presented at the event.

“You Can Touch”: How 3D Printing Is Transforming Museums

Over the past decade, museums and other cultural institutions around the world have become one of the most exciting testing grounds for 3D printing. Most likely, this is due to the nature of the objects that these institutions study, collect and display. Given their fragility and historical importance, they should not be touched and are usually displayed behind closed glass cases.

Historians Mirsini Samarudi and Karina Rodriguez Ekavarria talk about how 3D printing is changing museums and galleries.

You are allowed to touch

One of the most famous digital fabrication projects is a replica of Tutankhamun's tomb in the Valley of the Kings in Egypt, produced by Factum Arte. Thanks to the copy, tourists can visit the inside of the king's tomb without damaging the original.

At the same time, the American Museum of Natural History asked students to digitize, print, and collect dinosaur bones and identify their species, as paleontologists do; and the Metropolitan Museum of Art's MediaLab in New York has created edible replicas of museum artifacts made from chocolate, cheese and rice for visitors to enjoy.

In January, Google Arts & Culture, non-profit organization CyArk, and 3D printing company Stratasys announced their Open Heritage collaboration. They strive to preserve important monuments and artifacts from around the world and make them available to the public by reproducing small versions of cultural heritage sites.

All of these examples demonstrate the wide range of applications of 3D printing in culture and history. Some of them seem unusual, others may cause controversy around the veracity of "fake" replicas. But they all serve the same purpose: to enable people to learn, enjoy and appreciate cultural heritage through multi-sensory experiences.

The power of copies

Of course, copies of museum exhibits are not a new phenomenon. The touchable replicas have been produced by centuries of traditional methods. After all, the material aspect of objects plays a key role in our ability to perceive and understand the world. The ability to touch, explore shape, feel weight and even smell has the potential to transform our perception of cultural heritage.

How, then, do digital replicas differ from ordinary ones? Particular accuracy in relation to the shape of the original - after all, among other things, high-tech laser scanners are used for their manufacture. The power of digital copies also lies in their digital nature. They can be easily stored, edited and shared around the world.

People interested in cultural heritage can look at the replicas on the museum's website or 3D print them at home. More importantly, these digital copies can be easily modified or customized to meet different audience requirements.

Breaking Barriers

Given the variety of applications and popularity of the technology, learning how to perceive copies is becoming increasingly important. In our study, we want to shed light on the connection between the audience and the corporeality of replicas. Only after these connections have been analyzed will it be possible to design and produce better copies to meet the needs of the audience.

The study explores the potential of replicas to attract a diverse audience. For example, custom copies of objects can be made for visually impaired people to better understand and feel historical artifacts.

When showing a 3D printed exhibit at Booth Museum in Brighton to visually impaired visitors, we found that they needed some guidance to navigate the exhibit and its shapes. Complex shapes proved to be more difficult to understand. Visitors also suggested that having sound to complement the experience would play a big role.

In addition, while testing people's interactions with 3D printed artifacts at Brighton Museum, we noticed that visitors were hesitant to touch the replicas. Interesting - apparently, the copies inherited some of the qualities of the originals - in particular, that they cannot be touched. In such cases, clear direction, thoughtful design and audience motivation should overcome the fear of visitors to interact with cues.

Despite the efforts of the cultural heritage sector, it seems that there are still physical barriers between museum exhibits and people. But research and practice can only find ways to overcome them, one at a time.

3D printing of wax rings on an FDM printer for subsequent casting from metal

There was a need to print a wax ring to demonstrate to jewelers that it is generally possible to do it qualitatively on an FDM printer.

The only Russian-made Wax3D wax known to us from Filamentarno was chosen for printing!

A fairly complex 3D model of the ring was found on Thingiverse.com by MakeALot. You can download it here https://www.thingiverse.com/thing:7354

In general, this is a bracelet that turns into a ring if the model is reduced to the desired size.

By the way, there is a source file in OpenScad format that you can edit and make your own original ring if you want to deal with the code.

Here you can see the code that generates this 3D model. By changing the parameters, you can change the shape or remake the model in your own way, adding new commands.

Immediately to the question - is it possible to print large wax products on an FDM printer? Yes, we have already posted some results here:

https://3dtoday.ru/we-print/bolt-iz-voska

https://3dtoday.ru/we-print/patrubok-iz-voska

While printing small wax products, we encountered various problems and share with readers interesting notes on how to solve them, as well as some important settings that can be used with any 3D printer.

We reduced the bracelet/ring model itself to a diameter of 21 mm - just like a regular ring. Therefore, the vertical elements turned out to be very small with a minimum thickness of only 0.9mm!

It was necessary to accurately select the wax printing temperature with an accuracy of +-2 degrees.

It is possible to print from a temperature of 95°C, but in this case the wax coming out of the nozzle will be thick and small vertical elements will sway during printing, being carried along by the nozzle, because they are also soft, which will lead to a sharp deterioration in print quality.

Our ring just had a lot of vertical elements that should be printed perfectly. Therefore, we have chosen the optimal temperature of 105°C, when the melted wax comes out easily, but not so much that it leaks from the nozzle. If you raise the temperature above - up to 110 ° C, then thin hairs of wax will begin to appear on the part, which will worsen its appearance and require additional time for its processing.

Another problem was that many vertical elements had to be printed with feed back (retract). It turned out that the usual retract with raising the nozzle to a certain height of this ring is contraindicated, because drastically degrades print quality. Therefore, we left only the rollback of the bar itself to a minimum length of 0.1 mm to 0.5 mm without raising the nozzle.

Some settings in Cura 3D preparation software.

Printed with 0.5 mm nozzle, 0.1 and 0.04 mm layer.

As you know, in FDM printing, the optimal layer thickness is 2/3 of the nozzle diameter, which means that a layer of about 0.3 mm should be used. If you make the layer thinner, then various artifacts may appear.

If you want a thin layer to improve print quality, it is usually recommended to change the nozzle to another, smaller diameter. Naturally, this also increases the printing time. We had such a nozzle with a diameter of 0.25 mm. But, since we wanted to print faster, we decided to start printing from a diameter of 0. 5 mm, and at the same time see what the quality would be.

So, the results of printing the ring with wax.

Printing with 0.5 mm nozzle, 0.1 mm layer.

The result is far from perfect.

Decrease the height of the layer. Printing with a nozzle with a diameter of 0.5 mm, a layer of 0.04 mm.

The surface quality has improved, but there are artifacts that spoil the whole result.

Artifacts appear due to too thin a layer for this nozzle diameter. Please note that the entire ring consists of many inclined elements. The slopes are the most problematic.

Change to a smaller diameter nozzle 0.25 mm, layer 0.1 mm.

Surface quality improved, but small artifacts still present. In places where the nozzle moves from place to place, a small influx remains, which turns into a vertical seam. There are a huge number of such transitions, and by changing the settings for the seams, you can improve the quality of the print.

Changing the settings for seams in the slicer.

Nozzle Ø 0.25 mm, layer 0.1 mm.

Excellent result!

Yes, wax with complex geometries can be printed with a 0.25 mm nozzle, 0.1 mm layer with very good quality.

Unfortunately, with a further decrease in the layer height to 0.04 mm, the number of artifacts increases sharply for this complex model.

Therefore, we took another simpler model of the ring, where there are no separate and strongly inclined elements.

Model from the Printables resource of the author 3D_CNC. You can download it here https://www.printables.com/model/133544-knurl-ring-multiple-sizes-f3d-file

Printing nozzle 0.25 mm, layer 0.04 mm.

This is the result!

Such a thin layer of 0.04 mm gives maximum surface quality.

It is almost impossible to see the layers by eye.

Of course, FDM wax 3D printing will not replace photoresin printers for jewelers, but there are sure to be many not too complex shapes that can be printed in the way we have demonstrated.
