To meet the urgent need to medical shelters caused by the COVID-19 pandemic, Core Composites is developing its rapidly deployable Tupelo Flat emergency shelter solution, normally used by U.S. Military Command field hospitals.

Core Composites is working in partnership with ADS, an operations and logistics provider, to rapidly ready its Tupelo Flat Pack Shelter for use by hospitals needing extra capacity to deal with the COVID-19 pandemic. The Tupelo Flat has been used successfully by the U.S. military for field hospitals and other structures and can be used for all medical needs, including as virus testing, surgical bays, MRIs and x-rays, intensive care, and other medical operations.

Thanks to the composite panels, the flat packs are light, strong and durable, with the heaviest panel weighing only 200 pounds. The panels are also versatile, re-deployable and can be used in roofs, walls and floors. Each unit is 10’ x 10’ x 20’ and can be integrated to create larger spaces. The Tupelo Flat meets construction requirements, can be set up in rough terrain if needed, is fire retardant and meets medical operational requirements. The composite materials used to develop the Tupelo Flat make it resistant to corrosive agents such as toxic chemicals and extreme weather conditions. No material handling equipment is needed for set up and the Tupelo Flat can be assembled on site in just hours.

The shelter includes energy-efficient LED lights with wires recessed into the roofs, providing the illumination necessary for medical procedures.  The Tupelo Flat also provides electrical waterfall, is HVAC ready and has external water connections.

Core Composites is working with multiple manufacturers, composite fabricators and various raw material suppliers to produce 50 ready-to-ship units per month. Units are scheduled to be completed as early as May 2020.

MANSORY followed-up its successful conversion of an Audi RS6 estate car with the conversion of the Audi RS Q8 luxury SUV. The RS Q8 is based on the style of the RS6, with even more aggressive carbon fiber use and styling.

MANSORY modified several body parts to include carbon fiber, improving both the aerodynamics and downforce of the vehicle. The front and side skirts of the RS Q8 are now designed of carbon fiber and the rear skirt of the vehicle is finished in visible carbon fiber. The exterior of the SUV is black with red stripes and accents, adding to the sporty look.

The hood of the RS Q8 is also built of carbon fiber. All carbon fiber components of the vehicle are manufactured in MANSORY’s own autoclaves.

The interior of the MANSORY vehicle features the red and black motif as well and carbon fiber trim. Even the steering wheel is wrapped in a leather and carbon fiber hybrid.

As for the powerful engine, the 4.0-liter twin-turbo V8 in the RS Q8 features a modified ECU unit and a high-performance exhaust system. With 780 hp, the vehicle accelerates from 0 to 100 km/h in only 3.3 seconds and reaches a top speed of 320 kph.

Tires and wheels measure 10 x 24 and 12.5 x 24 inches with 295/30R24 and 355/25R24 fill the front and rear.  The MANSORY YN.5 forged wheel on the RS Q8 increases stability and improves handling. Y.5 aluminum rims measuring 10.5 x 23 inches are also available.

10 Tips for Converting a 3D Printer to Pellet Extrusion

Make the switch from extruded filament to closed-loop recycled plastic pellets with these helpful tips

The Lily pellet extruder on a SmartAlu printer designed by Smartfriendz

This project appears in Make: Vol. 75. Subscribe today for more great projects delivered right to your mailbox.

(Editor’s Note: Check back soon for more of Samer’s Lily testing updates.)

Converting a 3D printer to print directly from pellets requires tradeoffs: you’ll gain the ability to reuse plastic material in exchange for some performance limitations. Done carefully, these modifications will open the door to closed-loop recycling, economical pellet feedstock ($2–$5/kg), custom material blends, colors, and properties — but they could reduce the usable print volume and require slower print speeds due to the toolhead’s weight. Ten things to consider:

1. Can the carriage handle the weight and dimensions of the pellet extruder and hot end? Consult your vendor(s). We mounted the Lily pellet extruder on a SmartAlu printer designed by Smartfriendz.

2. Obtain a copy of the firmware on your printer — you may need to modify it. A lot of modifications can be stored in your slicer profile, but various offsets may have to be changed in firmware.

3. Your Z-axis endstop may have to move if the pellet extruder has a long hot end (the Lily does).

4. If you use a BLTouch or induction sensor for bed leveling, you might have to redesign a new X-carriage to accommodate these elements.

5. If possible, make the conversion on a secondary printer in case you need your main printer to prototype parts.

6. Decide how you will feed the pellet extruder. If you’re using a gravity feeder, the hopper has to be above the printer. The Lily pushes filament through a PTFE tube using air, so the pellets or shreds can be fed from any level.

7. While V-wheels are great, expect wear to increase with the heavier head. Consider upgrading at least the X-axis to use a linear rail.

8. If your kit comes with a MOSFET, use it. Running the pellet extruder may consume more power than your printer’s original design. Make sure your power supply can support the additional load.

9. Once it’s all installed, you’ll want to experiment with different materials to determine optimal print speeds, jerk settings, and retraction rates.

10. Expect to tune your PID values to suit your extruder. Recycl3D provided me with a baseline set of numbers and I tuned accordingly.

Whatever extruder you choose, seek support from your vendor, as this is a non-trivial endeavor. They’ll have complete details — Recycl3D was in close contact throughout my Lily installation over several weeks. Of course, if you’re using a DIY pellet extruder, the same checklist applies, but otherwise you’re on your own. You can find many #pelletextruder sources on YouTube, Thingiverse, and other sites.

This long holiday weekend is expected to challenge everyone’s resolve to stay safe.  We talk with Sabrina Paseman of FixtheMask.com about wearing masks, which types of masks work best, and which do not offer the best protection from COVID-19. We’ll also talk about why masks remain the best defense against COVID-19 and what kind of offense it is for people not to wear them.   Whether at a family gathering or while shopping on Black Friday, wearing a mask should be considered a civic duty, an obligation to protect yourself and others.

Date: Wednesday, November 25th @ 2:30pm PT / 5:30pm ET.

Join in the conversation or ask questions on Zoom or tune in on Facebook.

Sabrina Paseman is the CEO of Fix The Mask and a former Product Design Engineer at Apple. She holds a M.Eng in Mechanical Engineering from Cornell University. Through Fix The Mask she and her team are committed to providing fixes comfortable, affordable, accessible, and backed by data. Their mission is predicated on the idea that safety is a human right. The pandemic has shed light on the flaws of our healthcare system. PPE scarcity, misinformation, and price-gouging are all exacerbated by wealth inequality, racism, and systemic inefficiencies. Fix The Mask is committed to providing well-fitted masks for everyone and being an inspiration for the type of progress that can be achieved in a world of increasingly complex problems.

You can find the Surgical Mask Brace for purchase at FixThe Mask.com or check out Sabrina’s tips on creating your own.
