  • MachineWorks to Release Polygonica v1.4 for CFD, FEA

    machine-works-logoSHEFFIELD, UK, July 12, 2016 – MachineWorks Ltd, global supplier of CNC simulation and verification component software and of solid modelling software toolkit for processing polygon mesh will be releasing the Polygonica version 1.4 later this summer.

    120716_machineworksA sneaky peek of the new features are:

    The new remeshing API provides a way to modify the shape and size of the polygons representing a solid, while maintaining the overall shape and topology of the solid, in other words, altering the geometry to improve the quality of the solid. The aim of remeshing is to make more regular faceting, a highly desirable quality for algorithms used in computational fluid dynamics (CFD) or finite element analysis (FEA).

    Point cloud processing functionality is now much more comprehensive and suitable for interactive applications. Many extensions have been made including point cloud set registration, filtering, smoothing, sampling and normal calculation.

    Clash detection algorithms have been optimized and extended to allow the severity of a clash to be measured. A negative clash tolerance can now be specified to discount insignificant clashes where solids only marginally intersect each other.

    The Polygonica library now supports not only the Windows platform, but also MacOS and Linux.

  • 3DPrintClean Introduces Third Version of Air-Filtering 3D Printer Enclosure

    Two years ago, we first learned about 3DPrintClean, a 3D printer enclosure that not only contains the potentially harmful particles given off by 3D printers, but filters the air while the printer runs. While the product fell just short of meeting its Kickstarter goal in 2016, its creator, James Nordstrom, brought it to market anyway, and it’s been a success, selling hundreds of models and being further developed into a Model 2 production run.

    Now 3DPrintClean has reached out to let us know that they’re releasing a Model 3 version of the 3DPrintClean enclosure. The company has built up a very solid customer base including several schools, universities, libraries and other institutions that have a highly vested interest in keeping the air as safe and healthy as possible, as well as companies and agencies ranging from Samsung to John Deere to the Federal Aviation Administration. I’ve said it before – one of the biggest keys to a company’s success is ability to listen to its customers, and the 3DPrintClean team has shown that they value their customers’ opinions highly with the new features they’re introducing with the Model 3.

    “With hundreds of Model 2 enclosures in the field we have engineered the Model 3 series to include many requests from Model 2 customers,” 3DPrintClean Director of Sales & Marketing Mark Hulswit told 3DPrint.com. “We listened, we learned, we engineered. Our Model 3 series offers a complete solution for the education, public library, corporate and government markets. Enclosing the 3D printer allows for a controlled printing environment resulting in superior prints without exposing UFP’s or VOC’s to the room. It also allows for two lines of defense against a possible printer fire with our thermal cut off and automated fire suppression system feature.”

    The Model 3’s filter is much larger than the Model 2’s – 30 times larger, in fact, at 19 x 19″. The filter’s life cycle is also dramatically longer, at a full 365 days – the Model 2’s life cycle was only 90 days. It now offers numerous features that the previous models didn’t have, including:

    Touchscreen monitors for internal temperature, humidity, and thermal cut off temperature, as well as a filter change notification An optional stand Dehumidifier cabinet for PLA Dehumidifier cartridge for PLA Built-in WiFi Studio lighting USB pass-through connection Thermal cut-off feature that shuts down power if the printer gets too hot

    Optional automatic fire suppression feature

    Clean room honeycomb flooring has replaced the old wood flooring, and the enclosure door now features five-layer silicone rubber door seals instead of the brush seal that the Model 2 had. The Model 3 also offers dual and quad filament spool options. Above all, the Model 3, like its predecessors, was designed for safety – that’s the purpose of the entire product line, after all, to make 3D printing as safe as possible. The newest model still boasts an automatic fire suppression feature that, in the however-unlikely case of a printer fire, fills the enclosure with a fire suppressant powder like that used in a fire extinguisher.

    The 3DPrintClean enclosure uses 5.5 pounds of activated carbon to filter out all of the potentially harmful UFP and VOC emissions given off during a print job – and the Model 3 series now has a redesigned air flow system that increases efficiency for fast, safe, clean printing.

    There are actually two different types of enclosures in the series: the Model 660, with dimensions of 800 x 950 x 810 mm, and the Model 870, at 1020 x 950 x 1020 mm. The 660 will cost you $2,395, while the 870 is priced at $2,695. Stands, cabinets, fire suppression, spool holders and other accessories are sold separately.

  • They’ve 3D Printed the Pope!

    logo_staramba_80px (1)While 3D printing is responsible for changing so much of the world, throwing out tradition in favor of stronger, better, and more affordable products and processes–things have changed in other areas while we were busy with our heads down, rolling out innovations in PLA and ABS. For instance, the new Pope just seems to be getting hipper by the minute–from the Harley Davidson to ditching Congress for the homeless–and perhaps getting the common man’s attention–as well as taking us back to some common sense ideals.

    Surely he’s cool with the hippest new technologies as well. And we’ll see if the latest from a German 3D printing specialist happens to catch his eye. Now, a replica of Papa Francesco I – Jorge Mario Bergoglio is the first pope in history to be available as a 3D printed figurine for everyone who is interested in celebrating him in a high-tech manner.Untitled

    “Great news for the supporters and followers of the Catholic Church. Papa Francesco I – Jorge Mario Bergoglio is the first pope in history which is available as 3D printed figurine for everyone. The head of the Roman Catholic Church is well known for his support against environmental pollution, poverty and his great relationship with other religions,” Josh Weinberger of Forge 3D Printing told 3DPrint.com. “Staramba and the Forge 3D Printing Studio are proud to bring you the likeness of Pope Francis, just in time for his arrival in America. In 2013, Pope Benedict XVI was replaced by Pope Francis as Pope. A native of Argentina clergyman is the first pope who comes from America and the first pope to be available for everyone as a 3D figure.”

    Brought to the world by Staramba Arts and Entertainment, the likeness of Pope Francis, the 266th head of the Roman Catholic Church, has arrived in 3D print just in time for his visit to the US, and is quite a good likeness, we think. Staramba did the scanning and design work in Germany, and the figures will be shipped out by Staramba USA.

    popeReplacing Pope Benedict XVI in 2013, Pope Francis is surely one of the most charismatic popes in history. The piece is now available at Staramba’s online shop, with the scanning and printing produced at their Berlin headquarters.

    “Get the heavenly man including a base-plate showing the ceiling painting of the Dome of St. Peter’s Basilica in three different sizes in our online shop,” invites the team.

    You can actually find quite a collection of the Pope 3D prints by Staramba, with pieces retailing from $69.95 to $249.95, depending on size. Staramba offers the following models with various locales and features:photo 1

    Havana New York City Philadelphia St. Peter’s Basilica Washington, DC

    The 3D printed figurine is a photo-realistic replica made in full color and then hand finished. Most of the pieces are at a scale of 1:15, in full color sandstone, but there are two other sizes available at different prices as well.

    The 3D printed Pope also comes with a base plate which shows the ceiling painting of the Dome of St. Peter’s Basilica and measures 1.46 x 3.15 inches. If you order one of these 3D prints, you can look forward to it arriving in a very nice gift box too, complete with a Certificate of Authenticity and Care and Safety Instructions.

    Saramba has headquarters in Berlin, and specializes in photo-realistic 3D printed figurines, as well as selfies and other related 3D printed novelty items.

    “There is an infinite amount worthy to be noted: the wedding, an anniversary, the school enrollment, the festive ball, an appearance in a unique costume …With Staramba it is a reminder to touch,” says the team on their website.

    While Pope Francis is one of the more surprising novelty items we’ve seen in 3D print, the technology does offer great appeal and opportunity for businesses like Staramba, as well as those involved in marketing and branding endeavors. We’re curious to see what clever 3D prints Staramba comes out with next. Will you be ordering your 3D printed Pope Francis?

  • DAFF pledges support for a game changing NWU food and energy security project

    The Department of Agriculture, Forestry and Fisheries (DAFF) has pledged its support for the SUNfarming Food & Energy project at the North-West University (NWU), in Potchefstroom, in the North West province, which promotes the growing of and provides an opportunity to grow affordable and nutritious food in local municipalities, thereby effectively addressing household food and nutrition insecurity.

    The project is a partnership between Germany-based photovoltaic (PV) specialist SUNfarming and NWU.

    The project, which is co-financed by the German government, focuses on the application of technological engineering solutions and takes traditional, small-scale vegetable farming to new heights.

    Special so-called agrosolar greenhouse structures are used to grow vegetables, such as tomatoes, spinach, cauliflower, lettuce, cabbage, broccoli, onions and herbs. The project, which started production in June 2016, currently comprises three greenhouses or tunnels.

    Not only is agricultural produce grown, but the solar panels mounted on top of the tunnels generate electricity.

    Solar tunnel production also offers much higher yields than conventional farming. 

    No soil is required to grow the vegetables and water productivity is increased through drip irrigation.

    Through the project, several women from the local Ikageng community are being trained about cultivation methods, insect control, nutritional values of the different crops, root systems and harvesting techniques.
     
    “We are no longer planting our vegetables using the soil, but coco-fibre. Our system of farming saves water. Our vegetables pots are irrigated on time and we produce fresh vegetables,” Buni Maretlwa, one of the workers at SUNfarming, said.

    NWU and SUNfarming donated the initial plants, fertiliser and compost and the revenue generated from the produce will enable the community members to sustainably grow produce for many production cycles.

    At a site visit to the project this week, Agriculture, Forestry and Fisheries Minister Senzeni Zokwana said the project was “innovative technology for agriculture”.

    “We want to see this replicated in other parts of the country, as it effectively deals with the issue of climate change and the scarcity of water and land,” he said, calling for a partnership between government, higher learning institutions and business.

    Zokwana highlighted that initiatives such as these would help the department reach its goal of establishing one-million jobs in agriculture by 2030.

    “Agriculture is the answer to various problems. We need a doctor or dentist or attorney several times a year, but we need a farmer at least three times a day. We must strive for friendlier methods of agricultural production. What the NWU and SUNfarming are doing here, is the answer to these challenges we are facing within the agricultural sector.

    “What I saw today is the future of agriculture . . . It is important that these and other projects seek cooperation agreements with the private sector to expand it further across the province and country,” the Minister said.

    NWU Potchefstroom campus rector Professor Fika Janse van Rensburg said many communities would benefit from this initiative should it be rolled out on a bigger scale.

    SUNfarming’s objective is to roll out the project to all universities and schools in Africa and it is collaborating with universities in Kenya, Ghana, Zambia and Botswana, besides other countries, to achieve that goal.

    “Through the cooperation with African educational institutions, we seek to lay the groundwork for future investments and joint ventures between our company group and local communities in your country,” said SUNfarming founder Peter Schrum.

    He reiterated that energy is supplied to much-in-need communities while, “food security enjoys priority.”

    “Through this initiative, we also create the platform for more jobs and offer the opportunity for people to get themselves more educated,” he said.

    The project offers sustainable production opportunities for communities. It can create between 50 and 65 employment opportunities for each project, and offers an income opportunity that is a combination of food production and energy generation, according to Schrum.
