![]() Of course, getting PLA to stick to your 3D printing bed, smoothing PLA, or gluing PLA together are all topics for their own posts. ![]() If you’re 3D printing, PLA is your best starting material. PLA can also be made non-bioactive (like PCL) – though you’d need special formulations for it. While the one major downside of PLA is the it is not biodegradable and most of it ends up in landfills where it sits for many, many years, it’s made of natural starches, the odors it emits smell like cooked pancakes, it has decent mechanical properties, and it’s cheap-ish. PLA is a great all-around material for 3D printing (see our list of best PLA filaments here). If you’re drawing with a 3D pen, PCL is a great material to start with as it’s dead simple to use, flows nicely, and won’t leave you with burns. It’s also not bioactive, is FDA approved for use in implantable medical devices and will biodegrade in 1-2 years, making it a wonderful material for many low to non-load bearing applications. PCL is great in 3D printing pens for kids (and artistic adults!) or when you need a rubbery material that won’t take much stress. Yes, PCL is biodegradable and will typically break down in 2 to 4 years. So while it can be composted or degraded, it usually ends up in a landfill where PLA can take 100 to 1000 years to degrade. A mobility solution that harnesses the power of data and capture and sharing are the keys to streamlining your daily operations. This article in our Sharelus vs SharePoint comparison series explores the driving force behind a transformational enterprise mobility solution. PLA can be degraded in industrial composting facilities by heating it to 140 ☌ and adding special enzymes to it. A Comparison Between the Microsoft SharePoint Mobile App and Infragistics SharePlus: Transformational. ![]() This app allows the iPhone and iPad to serve more like a computer which is its overall goal. Whether they utilize it for work, social media, or even a personal diary it’s a great way to work on and export documents while being on a handheld device. It also means that you can extrude PCL right onto your hand and, due to the low melting point, probably not get burned – making it fantastic for kids. Filamente SharePoint has helped many people organize and receive important documents. This means that PCL is not good (at all!) for anything that needs to hold weight. This means PCL at room temperature is “rubbery” – it can be bent, flexed, and pulled apart (with some effort) with no additional heating. ![]() PCL has a melting point of 60 ☌ and a glass transition temperature of -60 ☌ (-76 ☏). The melting point and strength characteristics of PCL This means that PLA will keep most of its strength characteristics up until 60 ☌ (122 ☏), after which it’ll start to lose strength (it’s “storage modulus”)… in short, standard PLA is only useful until about 60 ☌. An example of strength characteristics of thermoplastics at increasing temperature. ![]()
