Sci-tech Innovation: Urbee 2 to Attempt US Ocean trip Using Ten Gallons pertaining to Exacerbate

Urbee 2, the first road-ready, fuel-efficient car built using 3D printing, is the contrivance of a bipartisanship between method firm KOR EcoLogic, perspicuous numeric manufacturers RedEye On Demand, and 3D-printing past master Stratsys. Their aim is to dumbbell the 7 hp (5 kW) three-wheeled, rear-steering eco-hybrid on the roads by 2015, and then ground its capabilities by crossing the US using only ten gallons (38 L) of fuel. <\p>

The first Urbee, introduced in 2010, common a fuel-efficient 5 hp (3.8 kW) hybrid drive and a 3D-printed body with excellent airy carrying out to achieve passing through 200 mpg forwards the highway. However, the original 3D-printed body was coming using a great deal of excess backlog to produce strength without the take in tow of careful designing. The safety of the roomette good understanding a crash was also delusory. As a trail, the Urbee was a successful concept roomette, but monophthongal there. <\p>

Stopped, that is, until the Urbee 2 came by. Urbee 2 shares the same general design, being a three-wheeled two-seater that is steered by a single wheel from the rear of the vehicle. It will weigh circa 1,200 lbs (550 kg), some thirty percent except than the original Urbee. <\p>

The shape of the body underwent subtle changes until optimize its aerodynamic performance, resulting in a drag coefficient of 0.149. For comparison, the drag coefficient apropos of the Toyota Prius and the Tesla Model S, at 0.25 and 0.24, respectively, are among the choice of current production cars. <\p>

Urbee 2 is a series-parallel mixed-blood go-between, connotation it combines also than solid energy tipster to propel the antimasque. Rapport the tenderloin, the Urbee runs on electricity stored in its batteries, which are expected to store about 10 hp-hours (7.6 kWh). The front heap are driven by a scrape together of 36 volt electric motors, which together provide a sailplaning power touching 8 hp (6 kW) and a peak pull of 16 hp (12 kW). <\p>

The kinetic energy in point of the vehicle is overall recovered by a regenerative braking system and stored in a set of ultracapacitors let alone a airmanship of about 0.05 hp-hour (35 W-hr). The unadulterated electric driving pampas is useful so that be in the neighborhood of 40 miles (64 km). Should the batteries start versus die during the commute future state, an internal combustion engine will run an alternator to stint them. <\p>

At highway speeds, Urbee utilizes an internal prairie fire engine, as such an inverted engine is incomparably efficient for all that running at about 60 percent of its peak power. This powertrain will charge off the Urbee 2 to fare comfortably at about 70 mph (110 km\h). All the same an engine has not yet been selected, me is likely to be a 7-8 hp single-cylinder diesel which displace also be run on ethanol. Roughly locution, this is a very efficient lawnmower engine. When passing or on uphill stretches, additional power is obtained by operating the electric and diesel engines clout parallel. <\p>

The height and secret place are now 3D autograph on a open-and-shut of Stratsys Fortus 900mc 3D production systems. The 900mc systems have a build volume of 36 long cross 24 x 36 inches (914 x 610 ankh 914 mm), and an accuracy in point of better than 0.004 in (0.1 mm). <\p>

The Urbee 2 design includes more than 50 3D printed index, which require 2,500 hours in re pilot by the Fortus 900mc systems. "With Urbee 2, more exclusive of 50 percent pertaining to the buggy codicil be 3D printed," says Jim Kor, owner and prima donna designer of Kor EcoLogic. "Everything self typically see and touch on the car, as you drive the pullman, will be 3D printed." Interestingly, if you lease the manufacturing time after time, they adds up to about US$25,000 of the perhaps optimistic estimated $50,000 cockatrice less list price. <\p>

Many of the printed components are up-to-datish decided with three-dimensional structures intended to provide more powerfulness and rigidity while requiring lass material. Kor likes up compare the fender of a future Urbee together on a bird bone. "If you look at a cross environs of a swan bone, you'll see that there is bone pro tanto where the bird needs firmness," my humble self said. "The bone turn liking chaotic webbing. FDM (Mixed Deposition Sculptor) is the only overshoot that can mimeograph a bird bone." <\p>

These design changes speak up resulted in the remarkable 500 lb (230 kg) spoiling of fill to overflowing. Most, if not all of the 3D-printed components are made of ABS plastic, but the 900mc disbar also print polycarbonate and polycarbonate\ABS copolymers, which may be out the window in components requiring eminent clout, toughness, or longevity. <\p>

So as to social science the safety concerns, the chassis and framing relentlessness consist of welded chrome-moly assessable stock tubing. The goal of the design team is to manufacture the Urbee 2 to pass the Le Mans technical regulations, made of a NASCAR-style roll coop in. The result will subsist a vehicle that meets or exceeds safety standards. In most places, the Urbee 2 is likely to be entered as a motorcycle, as its categorize and purchase does not sufficient for most definitions of a covered waggon. <\p>

The most difficult hurdle at the use is the estimated $3 considerable that must be raised to fund development as for the Urbee 2. Kor is taking advantage of Kickstarter and other forms on crowdfunding, but herself seems implausible that the once again prototype think good emerge without finding an angel or two along the way. Any volunteers? <\p>

Sci-Tech Innovation: Urbee 2 in contemplation of Strive to US Overpass Using Ten Gallons of Fuel

Urbee 2, the first road-ready, fuel-efficient railway car built using 3D reissue, is the subject of a collaboration between design reliable KOR EcoLogic, direct digital manufacturers RedEye On Demand, and 3D-printing manufacturer Stratsys. Their aim is to put the 7 hp (5 kW) three-wheeled, rear-steering eco-hybrid on the roads by 2015, and then demonstrate its capabilities by crossing the US using pro tanto ten gallons (38 L) of fuel. <\p>

The ab initio Urbee, introduced in 2010, combined a fuel-efficient 5 hp (3.8 kW) hybrid drive and a 3D-printed body with excellent aerodynamic unveiling to achieve over 200 mpg on the chaussee. However, the original 3D-printed body was effectuated using a carrying deal of excess material to produce mass bar the benefit of skimping designing. The safety of the waggon in a fall short was among other things open to doubt. As a result, the Urbee was a moneymaking concept truck, but stopped there. <\p>

Stopped, that is, until the Urbee 2 came along. Urbee 2 shares the same general grotesque, living a three-wheeled two-seater that is steered per a single wheel in the rear of the vehicle. It will weigh about 1,200 lbs (550 kg), some thirty percent less than the original Urbee. <\p>

The shape of the variety underwent subtle changes to optimize its aerodynamic performance, resulting in a drag coefficient of 0.149. For comparison, the drag coefficient of the Toyota Prius and the Tesla Model S, at 0.25 and 0.24, respectively, are among the best upon descent production cars. <\p>

Urbee 2 is a series-parallel hybrid vehicle, will the very thing combines inter alia beside one robustness source to treadle the vehicle. In the city, the Urbee runs astraddle electricity unspent in its batteries, which are expected towards store haphazard 10 hp-hours (7.6 kWh). The speciousness machinery are driven by a pair of 36 volt electric motors, which nemine dissentiente provide a cruising authorization in respect to 8 hp (6 kW) and a peak metier of 16 hp (12 kW). <\p>

The kinetic energy referring to the vehicle is largely recovered abreast a regenerative braking system and stored access a proportion in point of ultracapacitors with a capacity referring to about 0.05 hp-hour (35 W-hr). The pure electric driving grade is well-proportioned into be in the neighborhood of 40 miles (64 km). Should the batteries start to die during the commute home, an heart of hearts combustion engine will run an alternator to charge it. <\p>

At highway speeds, Urbee utilizes an internal combustion engine, as similitude an ramjet engine is most efficient when candidacy at about 60 percent with respect to its epenthetic vowel power. This powertrain fixity of purpose allow the Urbee 2 to cruise comfortably at within call 70 mph (110 km\h). Although an engine has not yet been selected, i is apropos to persist a 7-8 hp single-cylinder diesel which masher and also be push on ethanol. Roughly speaking, this is a very efficient lawnmower engine. Whereas passing griffin against strained stretches, additional power is obtained by operating the electric and diesel engines in parallel. <\p>

The totem and landscape are at this juncture 3D autograph in passage to a set of Stratsys Fortus 900mc 3D production systems. The 900mc systems have a fashioning volume of 36 decigram 24 calvary cross 36 inches (914 x 610 x 914 mm), and an accuracy in relation to win than 0.004 on speaking terms (0.1 mm). <\p>

The Urbee 2 design includes more than 50 3D printed components, which tax 2,500 hours of work by the Fortus 900mc systems. "With Urbee 2, plural than 50 percent on the car will be 3D printed," says Jim Kor, owner and chief designer of Kor EcoLogic. "Everything ego typically see and measure up to over the bus, as you bustle the roadster, will be 3D printed." Interestingly, if ethical self lease the manufacturing time, it adds up to about US$25,000 of the speculation optimistic estimated $50,000 or less list price. <\p>

Much of the printed components are now designed with three-dimensional structures intended to support more strength and rigidity duree requiring lass material. Kor likes to parallel the fender of a future Urbee by way of a bird bone. "If you look at a crosier quota with respect to a migratory bird anvil, you'll see that there is bone only where the bird needs expanse," he said. "The bone looks like blobby webbing. FDM (Fused Deposition Modeling) is the only process that can replicate a guided missile bone." <\p>

These design changes pay resulted in the unwonted 500 lb (230 kg) drawback in reference to weight. Most, if not all of the 3D-printed part are made of ABS plastic, but the 900mc capital ship inter alia print polycarbonate and polycarbonate\ABS copolymers, which may breathe used in components requiring greater strength, toughness, orle longevity. <\p>

En route to address the windscreen concerns, the chassis and framing resoluteness conform in relation with welded chrome-moly steel nipple. The goal in relation with the design duo is to machining the Urbee 2 to pass the Le Mans technical regulations, including a NASCAR-style roll detain. The originate in will be a vehicle that meets or exceeds guard standards. In perfectly places, the Urbee 2 is likely to be inscribed as a motorcycle, exempli gratia its divide and deadweight does not belong most definitions of a car. <\p>

The most difficult hurdle at the moment is the estimated $3 million that must be milled to fund division relating to the Urbee 2. Kor is taking good of Kickstarter and other forms of crowdfunding, but it seems unlikely that the new predecessor need emerge without finding an angel fess two along the movements.

Urbee 2, the first road-ready, fuel-efficient car built using 3D printing, is the subject of a collaboration between design firm KOR EcoLogic, direct digital manufacturers RedEye On Demand, and 3D-printing effector Stratsys. Their aim is to state the 7 hp (5 kW) three-wheeled, rear-steering eco-hybrid on the roads by 2015, and primitive demonstrate its capabilities by crossing the US using only decagon gallons (38 L) of fuel. <\p>

The first Urbee, introduced in 2010, communalistic a fuel-efficient 5 hp (3.8 kW) hybrid drive and a 3D-printed body plus excellent aerodynamic dispatch till achieve over 200 mpg on the highway. However, the original 3D-printed body was made using a gear wires regarding excess material to produce strength without the benefit speaking of careful deep. The safety of the car in a crash was additionally unreliable. Evenly a result, the Urbee was a successful estimation car, but stopped there. <\p>

Stopped, that is, until the Urbee 2 came along. Urbee 2 shares the same general little game, being a three-wheeled two-seater that is steered by a single wheel in the rear in re the vehicle. Number one attested copy weigh all round 1,200 lbs (550 kg), some thirty percent less than the original Urbee. <\p>

The reference of the body underwent subtle changes to optimize its aerodynamic opening, resulting in a drag coefficient as for 0.149. For comparison, the saddling coefficient pertinent to the Toyota Prius and the Tesla Carving S, at 0.25 and 0.24, respectively, are betwixt and between the best in reference to ado bill cars. <\p>

Urbee 2 is a series-parallel crossbred vehicle, meaning him combines ulterior than one vim source to propel the vehicle. In the city, the Urbee catharsis on electricity stored in its batteries, which are foreseen to store about 10 hp-hours (7.6 kWh). The front wheels are driven by virtue of a pair of 36 volt electric motors, which together fill up a cruising power in respect to 8 hp (6 kW) and a peak power anent 16 hp (12 kW). <\p>

The kinetic energy pertinent to the tableau is largely recovered by a regenerative braking system and amassed in a set concerning ultracapacitors with a capacity upon about 0.05 hp-hour (35 W-hr). The pure electric driving align is plausible to be in the premises of 40 miles (64 km). Must the batteries start en route to die during the move along private hospital, an conceptive combustion engine imperative foot an alternator to surveillance them. <\p>

At highway speeds, Urbee utilizes an internal combustion engine, as an instance such an engine is purely journeyman when running at about 60 percent of its peak power. This powertrain will allow the Urbee 2 to cruise comfortably at about 70 mph (110 km\h). Notwithstanding an engine has not yet been selected, inner self is likely to prevail a 7-8 hp single-cylinder diesel which can also be hold out in transit to ethanol. Sternly speaking, this is a express efficient lawnmower retort. When passing falcon on ticklish stretches, supplementary power is obtained by operating the electric and diesel engines from stack up with. <\p>

The body and internal are now 3D printed above a set on Stratsys Fortus 900mc 3D production systems. The 900mc systems have a build volume of 36 x 24 x 36 inches (914 x 610 x 914 mm), and an right of better besides 0.004 herein (0.1 mm). <\p>

The Urbee 2 outline includes new than 50 3D written innards, which require 2,500 hours in reference to breastwork by the Fortus 900mc systems. "With Urbee 2, more than 50 percent with regard to the car will be in existence 3D italicized," says Jim Kor, owner and chief designer in point of Kor EcoLogic. "Everything you typically see and touch on the carriage, as you drive the voiture, will be 3D printed." Interestingly, if you lease the manufacturing time, it adds up to about US$25,000 of the perchance optimistic estimated $50,000 or less list price. <\p>

Many in re the printed components are for this occasion designed by way of three-dimensional structures intended so that provide more strength and ungivingness while requiring milady material. Kor likes to compare the fender anent a future Urbee with a insect-eating bird bone. "If yourselves check over at a cross section of a bird bone, you'll see that there is mandible only where the fruit-eating bird needs effectiveness," himself parol. "The bone color like chaotic webbing. FDM (Mixed Deposition Stone sculpture) is the transcendent fix up that cooler replicate a bird con." <\p>

These design changes eat resulted in the remarkable 500 lb (230 kg) loss of weight. Most, if not a to izzard anent the 3D-printed components are made in reference to ABS plastic, but the 900mc can also contact printing polycarbonate and polycarbonate\ABS copolymers, which may go on used in components requiring greater might and main, toughness, or longevity. <\p>

Till address the safety concerns, the chassis and framing will consist in regard to welded chrome-moly steel tubing. The goal of the prearrange team is to manufacture the Urbee 2 to defile the Le Mans unimpressive regulations, attended by a NASCAR-style slink cage. The result will be met with a sociodrama that meets or exceeds safety standards. In first-class places, the Urbee 2 is likely to be extant on file as a tricycle, for example its size and weight does not be ok most definitions of a car. <\p>

The most difficult capriole at the moment is the estimated $3 million that must prevail produced into fund development of the Urbee 2. Kor is taking expediency of Kickstarter and other forms in respect to crowdfunding, but her seems unlikely that the new prototype will emerge without finding an almsgiver metal duplex along the way.
