All your 3D printing questions answered

first_imgSarah Tew/CNET Rounding up some of the best budget 3D printers, I learned a lot about the art and science of printing. It’s not as simple as loading a 3D file, hitting print and sitting back, although the extra steps and follow-up work involved is well worth it if you want to create eye-catching stuff.  These are some of the big beginner questions I’ve gotten, and the major things I’ve learned through trial and error. Mostly error. These tips are deliberately simplified for a beginner audience. To really dive deep, check out the very active Reddit 3D printing community.  Crazy things I’ve made on a 3D printer Now playing: Watch this: Tags Comment 18 Photos How food dye could help create 3D-printed lungs What material should I use to print with? Most home 3D printers use PLA or ABS plastic. Professional printers can use all sorts of materials, from metal to organic filament. Some printers use a liquid resin, which is much more difficult to handle. As a beginner, use PLA. It’s nontoxic, made mostly of cornstarch and sugarcane, handles easily and is inexpensive. However, it’s more sensitive to heat, so don’t leave your 3D prints on the dashboard of a car on a hot day.  Which brand of PLA is best? Generally speaking, Hatchbox has never let me down, and runs about $20 for a full 1kg spool on Amazon. Some of the printers I tested only accommodate narrower 0.5kg spools. In those cases, I sometimes used a larger Hatchbox roll with a separate spool-holder (which, yes, I 3D-printed). Other times, I had good luck with AIO Robotics 0.5kg spools, which are a little more expensive, at $14 for 0.5kg. A 1kg roll prints a lot of stuff.  center_img Share your voice Computers 3D Printers 1 What color filament should I use? I found most prints look best in plain white, if you’re not going to otherwise prime or paint them. Primary colors are easy to use, but every time I tried something like a metallic or other unusual color, many of my prints were spotty or brittle.  What settings should I use? Most 3D printers include or link to recommended software, which can handle converting 3D STL or other files into formats supported by the printer. Stick with the suggested presets to start, with one exception. I’ve started adding a raft, or bottom layer of filament, to nearly everything I print. It has cut down dramatically on prints that don’t adhere to the bed properly, which is a common issue. If you continue to have problems, rub a standard glue stick on the print bed right before printing. What are supports? Your 3D models probably need some help to print properly, as these printers don’t do well with big overhangs — for example, an arm sticking out from a figure. Your 3D printer software can usually automatically calculate and add supports, meaning little stands that hold up all those sticking-out parts of the model. After the print is done, clip the supports off with micro cutters and file down any nubs or rough edges with hobby files.  Where do I find things to print?  Thingiverse.com is a huge online repository of 3D files for anything and everything you can think of. Pokemon chess set? It’s there. Dyson vacuum wall mount? It’s there. DIY Lego-style blocks? Yep.  When you’re ready to create your own designs, there are a ton of software packages to choose from, but it’s easiest to start with the browser-based free TinkerCad app from Autodesk.  Which 3D printer should I buy?

Moving a step ahead

first_imgNational Museum Institute took a major stride in realising an independent campus for the 25-year-old educational centre when Union Minister of State for Culture and Tourism, Mahesh Sharma laid the foundation stone of the institute at a three-acre plot in Noida on January 31.The National Museum Institute of History of Art, Conservation and Museology (NMI) will get a five-storeyed complex in its new premises at Sector 62 in 30 months with an estimated expenditure of Rs 90 crore, thus set to become a one-of-its-kind national resource centre for post-graduate and doctoral studies in art and heritage. “The institute will be a milestone in the future history of Noida and also for the country,” the minister said after unveiling the plaque at the function.Sharma noted that the eco-friendly institute with hostel facilities would generate more jobs and invigorate heritage upkeep in India.  The 1989-founded NMI currently functions at National Museum premises in Delhi. Vasudevan said, “The institute will provide five post-graduate courses on Art history, Conservation and Museology. There will also be short-term courses for imparting of certain skills associated with the field,” he added.last_img read more

Guy calls out airline for handing out sweets to kids and suggests

first_img Posted by Thursday, May 9, 2019 Share Guy calls out airline for handing out sweets to kids and suggests this as an alternative treat instead Travelweek Group center_img WELLINGTON  — Don’t take candy from strangers – or from airlines, says one particularly health-conscious traveller.As reported in the NZ Herald, Freddie Coltart, who recently flew with Air New Zealand, took to Facebook to call the carrier out for distributing candy onboard to kids.He wrote: “Hi Air NZ, When I was flying a few weeks ago I noticed that a little boy was handing out sweets on the flight. I know you’ve been doing this for years but don’t you think this might have become outdated? Kids eating sweets is bad for their dental and physical health.”But if you think Coltart simply left it at that, think again. He went so far as to suggest an alternative ‘sweet treat’, one that would be much healthier for young tots.His solution? Hand out prunes instead.“What about handing out single serving prunes instead?” he added. “As one of NZ’s biggest brands it would be good to be encouraging clean eating and healthy digestion.”More news:  Save the dates! Goway’s Africa Roadshow is backHe signed off encouraging Air New Zealand to “consider the prune”.His post went viral, garnering close to 7,000 comments on Facebook. Not surprisingly, many of the comments slammed Coltart for being a bit clueless (again, we’re talking about prunes here), with people quickly pointing out candies’ dual-purpose on planes.“The whole idea of sucking on a sweet is to equalize the pressure in your ears while the plane is descending,” wrote Brent Hodder.Others didn’t think prunes would be a particularly ‘digestically’-sound option.Judy Haldane wrote: “Prunes? How many toilets are on Air NZ planes for how many passengers?!?!!”Many people didn’t have the patience to even deal with Coltart. Gayle Sinclair wrote, “You know where you can put your prunes Freddie” while Kyle McGovan responded with a simple “No just no.”And Delwyn Luke, who perhaps had the best advice out of everyone, wrote: “Why get rid of what works, it’s up to the parents to sort out dental hygiene, not the airline.” Tags: Air New Zealand, Food, Funny << Previous PostNext Post >>last_img read more
