Copenhagen, Denmark (UroToday.com) Improvements in surgical techniques and outcomes have come as a result of improved anatomical knowledge gained through ever more powerful imaging techniques. The point of most imaging is to recapitulate patient-specific anatomy so that a surgeon can make the best operative plan and provide the most precise surgery possible for each individual patient.
Dr. Ukimura and colleagues have capitalized on advances in 3D printing technology to take this science to the next level. Using multiparametric MRI imaging as a reference, their team has demonstrated that printing a 3D model of a prostate is both feasible and useful. The team was able to create models using a flexible material that precisely demonstrates target cancer lesions in 3-dimensional space. This helps to characterize the lesions with respect to the location in the prostate, the location relative to the prostate capsule, and the location relative to the neurovascular bundles (NVBs).
Having a good 3D knowledge of these relationships can obviously make a huge difference during prostate surgery. It can help a surgeon know where to absolutely avoid a capsulotomy and where to take wider dissection planes, for example, in order to minimize risks of positive margins and to maximize the preservation of NVBs.
This technology will really be useful for the field of focal therapy, as the models can be useful for research purposes as well as for patient-specific planning of needle placement for ablation probes, for example. However, prostate cancer does not always present in “index lesions,” and clinicians should be mindful that these models are built off of imaging patterns from mpMRI and can miss more diffuse carcinoma throughout the prostate. Thus, one should exercise appropriate caution, as usual, when using these models for surgical planning.
This is a very interesting new technology that can revolutionize the way future surgeons plan surgeries, as long as the 3D printing technology becomes more available and cost-effective. As an added bonus, it can also help with surgical instruction/resident teaching. Lastly, it can be used for counseling patients about their surgery in a way that has never before been possible!

“We welcome Eye2Eye to our fast-growing community of partners. I am delighted that our first partner in APAC is located in Singapore, given my long-standing relationship with that great country,” said Rize President and CEO Andy Kalambi. “I spent a lot of time in Singapore and was privileged to see the growth of key companies there, such as SAP, MatrixOne and Dassault Systèmes. With Eye2Eye, Rize has become a truly global company, with partners now located throughout APAC, Europe and North America.”
Arcam AB Delisted From Stock Exchange
In 2016, GE announced its intention to acquire Swedish metal additive manufacturing provider Arcam, well-known for its innovative Electron Beam Melting (EBM) technology, in a public cash offer. GE completed its purchase of 76.15% of controlling shares of Arcam in December 2016, and recently surpassed 90% ownership of Arcam AB shares, which, in accordance with the Swedish Companies Act, allowed for the initiation of the compulsory buy-out of the remaining shares by GE.
Today, the GE Additive company has officially delisted from the Nasdaq Stockholm exchange. Arcam’s delisting will allow for a “more fulsome integration with GE,” according to the release, and the last full day of trading of Arcam stock was on January 26, 2018.
Aerosint’s Multi-Powder Deposition Could Transform Industrial 3D Printing

Belgium-based startup Aerosint, founded in 2016, introduced its patent-pending powder bed 3D printing process to the world in 2017. The company has a fundamentally different approach to multi-material powder deposition, in that it selectively deposits powder material from a rotating drum that passes over a build area, rather than using several complex actuated nozzles; two drums are used to achieve multi-powder deposition in a line-by-line technique at rates of up to 200 mm per second. The process is also less sensitive to powder characteristics than techniques which use pipettes.
Dr. Kevin Eckes, an American biomedical engineering PhD working as an R&D engineer at Aerosint, explains in a Medium post that in order to introduce new opportunities in a competitive market, the 3D printing world needs to rethink the approach in powder fusion-based additive manufacturing.
“The maturation of multi-powder deposition techniques, whether pipette-based, drum-based, or otherwise, will no doubt open up a sea of opportunities for manufacturers,” Dr. Eckes wrote. “In addition to the benefits of powder waste reduction, material cost savings, and reduction of post-processing time, we see several areas of opportunity that can only be realized on an industrial scale using a multi-powder approach.”
To learn more about these areas of opportunity, and multi-powder deposition in general, check out the full post. Aerosint will also be releasing more perspectives about the benefits and applications of multi-powder deposition in the future.
According to the paper, “In the authors’ technique, standard epilepsy evaluation and neuroimaging are used to create a hypothesis-driven SEEG plan, which informs the 3D printing of a novel single-path, multiple-trajectory, omnidirectional platform. Following skull-anchor platform fixation, electrodes are sequentially inserted according to the preoperative plan. The authors describe their surgical experience and technique based on a review of all cases, adult and pediatric, in which patients underwent invasive epilepsy monitoring via SEEG during an 18-month period at Vanderbilt University Medical Center. Platform and anatomical variables influencing localization error were evaluated using multivariate linear regression.”
Xometry to Compare Additive and Subtractive Manufacturing at SWW18
Next week, SOLIDWORKS World 2018 will be held in Los Angeles, and Xometry, one of the top online marketplaces for custom manufactured parts, will be attending the event. The company’s instant quoting platform provides feedback and prices for your parts in several additive and subtractive processes, though once they’re optimized, it can’t tell you which type you should use. At SWW18, Xometry’s Director of Applications Engineering, Greg Paulsen, will be offering an expert comparison between the two at the third Additive Manufacturing Symposium session.
At Paulsen’s session, titled “Additive vs Subtractive Manufacturing and Subtractive for Additive,” he will discuss how both methods are able to create precise parts, but that they each have different considerations and benefits to consider before you decide. After the session, you can stop by Xometry’s booth #223 in the SWW Partner Pavilion to see its instant quoting platform for yourself, along with its Add-In for SOLIDWORKS, meet team members to discuss your parts, pick up manufacturing toolkits and SLS Xometry/SOLIDWORKS-branded spinners, and enter a raffle for the chance to win $500 in parts.

Just as it does every year, CES 2018 is proving to be a hotbed for exciting new 3D printer releases. We’ve already seen new products from companies like Airwolf 3D and Polaroid, and now Nexa3D—the present venture of former 3D Systems CEO Avi Reichental—is demonstrating its NXV professional SLA 3D printer. Priced at $19,950 per system, the NXV SLA 3D printer is capable of printing 30 micron XY resolutions.
The NXV is equipped with cognitive software and integrated sensors, both of which optimize manufacturing part performance, and provides detailed diagnostics and continuous monitoring. It uses deep machine learning algorithms to slice, optimize, and adaptively compile complex geometries at uniform speed and high resolution, allowing users to print the right parts in the right way via the most cost-effective and time-saving route.
According to the company, the NXV 3D printer is easy to operate across different situations too, as it is configured to run using both on-board and cloud controls for in-situ and remote operations — of either a single printer, or a full factory of printers. Putting multiple NXVs together enables the mass production of customized parts.
As future 3D printers in the Nexa3D range will be, the NXV is powered by the company’s proprietary Lubricant Sublayer Photo-curing (LSPc) technology and patented structured light matrix, which is capable of reaching top speeds of 1 cm per minute. This phenomenal speed cuts the time needed for the 3D printing of precision functional parts from hours to minutes, making 3D printing a viable challenger to injection molding.
“3D printing is an unstoppable force of change in every industry and within it, high-speed 3D printing is the next frontier in additive manufacturing and one that is highly valued by end-users, strategic partners, resellers, and investors alike,” commented Reichental. “After several years of bootstrapping through the early stages of proving and nailing our game-changing technology, we are gratified to be here at CES 2018.”
It’s a busy time for Nexa3D, which has been doing much more than developing its NXV 3D printer. In November, we reported that the company had partnered with BEGO and XYZprinting to jointly develop and commercialize 3D printing technology for the dental industry. Under the agreement, BEGO will exclusively market and sell, under its own label, a special purpose high-speed Nexa3D dental printer that will be manufactured by XYZprinting.
Nexa3D is also revving up its interest in the automotive industry, having joined the Techniplas open innovation program, which encourages the sharing of technologies to create new opportunities within the 3D printing industry. As a full innovation partner, Nexa3D is using CES 2018 to showcase 3D printed automotive innovations alongside other additive manufacturing companies within the expanding Techniplas ecosystem.
The Nexa3D-Techniplas connection is clearly strengthened by the fact that Reichental heads the Techniplas 3D printing division, which was established in June 2017.
New research forecasts the size and shape of the consumer 3D printing market
Hampshire, UK – 22nd April 2014: New findings from leading hi-tech analysts, Juniper Research, reveal that sales of consumer 3D printers will exceed 1 million units by 2018, rising from just over an estimated 44,000 this year.
While shipments are at relatively low levels, representing a limited opportunity in the medium term, Juniper expects them to increase significantly beyond the five-year period. This will be a result of an ever widening scope of applicability, driven by the entry and growth of the more established printing vendors, such as HP. This in turn will be coupled with a more attractive pricing proposition for consumers.
The established printing vendors have also yet to ‘show their cards’, but niche and novelty applications are on the increase. For instance, companies such as Hasbro and Hersheys are working with 3D printing vendors to develop unique applications for consumer use.
Hype or Long-term Opportunity?
The report also observed that with the widespread technological awareness amongst consumers, it is now much easier to generate interest, and possibly hype, for new products and applications. This however, does not always translate into shipped products.
Report author Nitin Bhas added: “Educating and motivating the public on the idea of 3D printing, to create everyday objects is critical for the long-term success of this segment. Killer applications and content will be the key drivers – something unique and personalised, which is not available in stores already”.
The whitepaper, ‘3D Printing ~ Cutting through the Hype’ is available to download from the Juniper website together with further details of the full report and Interactive Forecast Excel (IFxl). Juniper Research’s highly granular IFxls enable clients to manipulate forecast charts and tables, perform what-if analysis; and compare select markets.
