3-D printers prep Creston Tornado students for the real world confirmed in eastern Iowa
By KELSEY HAUGEN CNA staff reporter khaugen@crestonnews.com
Before computer-aided design (CAD) existed, product designers had to draw by hand, manually build a prototype and then test the prototype before building the actual product. Today, thanks to CAD, a computerized drawing can be rapidly transformed into a physical prototype through a type of industrial robot: a 3-D printer. A 3-D printer takes a computerized image and replicates it as a 3-D object, using the drawing’s exact measurements. This is the reality of today’s design world, and Creston students in technology-based classes are experiencing this reality in their use of 3-D printers at school. “What they’re learning is an engineering-related curriculum,” said Phil Wardenburg, Creston High School industrial education and technology teacher. “(CAD) can also be very helpful with their blueprint-reading skills – to take a drawing, visualize those dimensions and know what they mean. The skills they develop (through CAD) are related to a lot of other courses we teach here at Creston Schools.” This year, the 21st century classrooms in both the high school and middle school each received their first 3-D printer. Wardenburg has had two 3-D printers in his classroom since 2014 – a smaller printer that cost about $3,500 and a large printer worth more than $7,000 – for a total of four 3-D printers between the schools. The printers were paid for through the federal Perkins Act, which provides funding for vocational and technical education.

Once the image is exported, it can be made into a 3-D image in computer aided design (CAD) and printed as a plastic object on a 3-D printer. Also pictured is Creston Schools technology integrator Teri Keeler.

A student can design a 3-D image using CAD, as shown on the computer to the right, and print the object on a 3-D printer. For video of a 3-D printer at work, visit crestonnews.com.
3-D printing In creating an object using CAD, the first step is sketching two dimensions – length and width. “If there are details involved, like cuts, arcs (and) rounds, they develop those on there,” Wardenburg said. Then, the designer brings in the third-dimensional plane, which is depth. Once depth is developed, the designer may have additional
work to do on the drawing, depending on the product being designed. “This is why engineers make some nice dollars. There’s so much detail involved in the products we buy and that you and I as consumers demand,” Wardenburg said. “We demand that precision.” Then, the designer brings in dimensions – whether it be fractions, the decimal inch or metric system.
“Now, they’re going to fine tune the part they designed into precision measurements,” Wardenburg said. “Then, fundamentally, they’re pretty much done. It is saved as a CAD drawing and a three-dimensional drawing, too. Once it is saved as a three-dimensional file, the part can be printed off using a 3-D printer.” A 3-D printer uses plastic filament, which can cost as 3-D | 2A

CLINTON (AP) — The National Weather Service confirmed Wednesday that tornadoes touched down in parts of eastern Iowa that also endured heavy rain and hail as large as golf balls. The Weather Service said the Tuesday evening storms that damaged buildings and caused minor injuries included three tornadoes that touched down in Clinton County. A tornado that swept through the Royal Pines Village Mobile Home Park in Clinton was classified as an EF-1 with winds reaching 90 mph. The tornado, which was on the ground for more than a mile, destroyed five mobile homes and damaged a number of others. At least three people were injured. Clinton County Emergency Management said the damaged homes’ natural gas pipes released gas into the air. As utility workers made repairs, the park’s utilities were turned off for a time, so about 70 residents were tak-
en to the airport for temporary shelter. Clinton Mayor Mark Vulich said all 82 park residents were accounted for Tuesday night. Two other tornadoes touched down in the area, including one near Andover with winds up to 95 mph and one that hit near McCausland with winds of 85 mph. Hail up to 1.75 inches in diameter was reported north of Grandview in Louisa County, and an inch or more of rain left standing water up to a foot deep in Lee County low spots, the weather service said. Trees and power lines were knocked down in Clinton, DeWitt and elsewhere in Clinton County, and a fuel tank was reported to have blown over south of Andover. Electricity was knocked out briefly in nearby Scott County. LeClaire police said some power poles had been toppled and some streets were littered with debris.
Trump as GOP nominee could lean on party money WASHINGTON (AP) — Donald Trump says he’ll raise money for the Republican Party and there’s a good reason why: It has the resources he lacks for a general election. Trump’s victories this week make it much more likely that he’ll be the party’s presidential nominee, probably facing off in November with Democrat Hillary Trump Clinton. That raises the question of how a so-far “self-funding” Trump would pay for what could be a billion-dollar campaign. The answer could be, in part, the Republican National Committee. In the four years since Mitt Romney lost to President Barack Obama, the party has spent millions of dollars to identify and persuade voters by building up its data team and deploying hundreds of on-the-ground employees across the country. These specialties of the national party happen to be lacking in Trump’s own
campaign. As nominee, he would inherit those RNC resources, which would grow even stronger with Trump’s fundraising assistance. He could also add personnel to the RNC’s leadership, further blending his campaign and the party. RNC Chairman Reince Priebus and Lewis Eisenberg, its national finance chairman, have made repeated public assurances that they would support Trump if he becomes the nominee. Eisenberg, a New Jersey investor, has known Trump for several decades. Another longtime party financier, Bill Palatucci, plans to raise money for Trump in some capacity. Palatucci’s friend and political ally, New Jersey Gov. Chris Christie, was one of the first mainstream politicians to endorse Trump. “The nominee will take over a party that has resources that simply weren’t there for Mitt Romney,” Palatucci said. The RNC has consistently raised millions more than its Democratic counterpart in recent years. After Romney’s loss, the GOP | 2A
