Shapeways Introduces Gold Plated Brass to 3D Printing
Shapeways Brings the Bling to 3D Printing
3D printing marketplace Shapeways announced a new 3D printable material, gold plated brass.
“Gold Plated Brass is a rich, highly polished material that’s perfect for jewelry and precious objects. The base is solid brass, and the gold plating gives it a smooth, beautiful finish,” says Savannah from Shapeways Marketing team.
3D printing in gold plated brass is actually a 5-step process
First, the model is printed in a wax using a specialized, high-resolution 3D printer. It is then put in a container where liquid plaster is poured in around it. Once the plaster sets, the wax is melted out in a furnace, and the remaining plaster becomes the mold. Molten brass is poured into this mold and allowed to harden. The plaster is broken away, and the brass piece is cleaned and polished. Finally, this piece is electroplated with a thin layer of nickel for durability and an outer layer of high quality 24K gold. The result is a smooth gloss finish comparable to a solid gold item.

Price per cm3: $35.00
Minimum Wall: 0.8mm
Max Bounding Box: 100 x 100 x 30 mm

Study Shows 3D Printing Emits Ultrafine Particles; What This Actually Means
Should You Use Your 3D Printer Indoors? Study Asks, We Explain
A recent study published in the journal Atmospheric Environment shows evidence that desktop 3D printers emit ultrafine particles (UFP) to a degree that should cause concern, if you operate your 3D printer in a telephone booth.
The report focuses on emissions by FDM (fused deposition modeling) printers that use ABS or PLA material, a configuration used by MakerBot and other popular desktop 3D printer companies.
Ultrafine particles are small particles, technically on the nanoscale, that can be inhaled and cause health effects ranging from innocuous to major, including lung disease.
The report claims that observed emissions of UFPs from desktop 3D printers were significant and therefore caution should be used when operating in a unventilated area.
Estimates of emission rates of total UFPs were large, ranging from ∼2.0 × 1010 # min−1 for a 3D printer utilizing a polylactic acid (PLA) feedstock to ∼1.9 × 1011 # min−1 for the same type of 3D printer utilizing a higher temperature acrylonitrile butadiene styrene (ABS) thermoplastic feedstock. Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments.
At first glance, this sounds like a big problem for 3D printing, an industry in rapid growth and adoption. But the reality is that the level of emission observed is similar to that of laser printers, candles, and cooking on a stove at home – all activities consumers are not going to give up any time soon.
The same 3D printer utilizing a higher temperature ABS feedstock had an emission rate estimate (1.8–2.0 × 1011 # min−1) similar to that reported during grilling food on gas or electric stoves at low power (1.2–2.9 × 1011 # min−1), but approximately an order of magnitude lower than gas or electric stoves operating at high power (1.2–3.4 × 1012 # min−1). Regardless, the desktop 3D printers measured herein can all be classified as “high emitters” with UFP emission rates greater than 1010 particles per min, according to criteria set forth in He et al. (2007).
In summary, don’t use your 3D printer in a dark corner of your basement without opening the window.

Inside 3D Printing Chicago Conference – A Full Retrospective
Inside 3D Printing Chicago – What We Saw
Looking ahead to the next Inside 3D Printing conference in San Jose (September 17-18, 2013), we’ve identified some of the key takeaways from the most recent Inside 3D Printing Conference and Expo in Chicago. The below summary lays out both what we learned during the conference about recent developments in the 3D printing (additive manufacturing) revolution and some of the core challenges still facing the industry. Through their insightful remarks, Inside 3D Printing’s speakers made clear that this technology is capable of unleashing human creativity beyond the limits of what we consider possible today.
Professor Hod Lipson emphasized during his lecture that the future of 3D printing is one of portable, instant manufacturing where complexity is free, and we can create any object we are capable of imagining with zero constraints and zero lead time. Prof. Lipson’s lecture, along with keynotes by industry heavyweights and a range of tutorial presentations, made clear that the industry continues to make significant strides forward.
Among these positive developments is the fact that, according to Lipson, better, cheaper and faster machines continue to be introduced in a wider range of materials. Conference exhibitors presented machines capable of printing in alternative materials like copy paper, wood, and rubber-like plastic materials, among many others. Speakers also emphasized that makers and scholars are working to increase the use of natural raw materials in 3D printing processes, which now include sawdust, salt and wood, among others. It is also possible to print in more environmentally friendly materials such as bioplastics and in live materials such as human cells.
It is also worth noting that today’s 3D printers can print functional parts in multiple materials seamlessly and with no assembly required. These parts have already met with a wide range of applications, including engine parts, prosthetics and outer casings for electronic components, among others. Prof. Lipson anticipates that future printers will be able to create and combine new forms of materials, as well as print integrated systems containing electrical and later digital components.
Importantly, 3D printing has allowed designers to consider a new approach to design. Inside 3D Printing made clear that the concept of “design for manufacture” is starting to fade with the onset of 3D printing. Conference presenters Isaac Katz, Michael Schmidt and Francis Bitonti noted that artists and designers are now able to design and 3D print virtually any geometric structure their minds can conjure. This ability, when paired with the high precision capability of virtual effects and CAD software, now allows designers and makers to think about creating as nature does. The ultimate impact of this exciting development is that the objects we make can now reflect the organic, layered, fluid and undulating structures found in nature – structures that would be cost prohibitive or impossible to make otherwise.
Inside 3D Printing also provided an opportunity for Michael Raphael of Direct Dimensions to update participants on the impressive capability of 3D scanning technologies. Raphael noted that, 3D scanning technology has also seen ”massive change” over the past three years thanks to the growth of the 3D printing industry and other technologies like smartphones and GPS. Scanning equipment has become more powerful, portable, and affordable. In the past three years, the price of high end scanning equipment has decreased dramatically, with gear that formerly carried a price tag of over $100,000 now available for purchase for under $1,000. Mobile and video game applications like 123D Catch and Microsoft Kinect have also made 3D scanning technology more widely available and this trend is expected to continue with the release of the Kinect 2. Applications for 3D scanning technologies are also wide ranging, from current uses in high definition surveying to potential future uses in mass customer apparel.
At Inside 3D Printing Chicago, attendees were able to watch industry leaders engage the market in new ways. For example, 3D Systems CEO Avi Reichental announced during his keynote speech a new strategic alliance with Deloitte to assist companies in adopting 3D printing design and manufacturing solutions. Disney Entrepreneur in Residence Cydni Tetro also evaluated the role of 3D printing in retail and illustrated how the Disney Company has applied 3D printing technology to create premium retail experiences like the “Carbon-Freeze Me Experience,” which allows Star Wars fans to purchase a 3D printed image of themselves appearing to be frozen in carbonite.
In addition to highlighting these and many other exciting developments in the industry, Inside 3D Printing also raised a number of questions about the future of the technology and its impact on existing processes. As the technology develops, 3D Printing has identified several key questions for industry participants to consider moving forward:
- How will materials experts within the industry, as well as the maker community, continue to harness the technology into practical applications and make it widely accessible?
- What will be the environmental impact of 3D printing, and how will the ability to print objects in more varied and earth-friendly materials develop?
- What will be the social impact of this technology?
Ultimately, despite the naysayers, Inside 3D Printing provided an opportunity for speakers, exhibitors and attendees to share their progress, identify key priorities, and show how 3D printing will transform our future.
