Uživatelé mohou snížit průtok materiálu o 65 %, aby dosáhli lehčích dílů, nebo využít vlastností roztažnosti pro efektivní zkrácení doby tisku pomocí velkých výšek vrstev nebo jednotlivých mimořádně silných obvodů. My printer is an Anycubic Kossel Linear Plus delta printer that was equipped with a Titan-clone extruder. The hot end is an e3d clone with a Teflon lined heat break.
So what is LW-PLA good for: well, ignoring its efficacy for reducing printing time, it is obviously very suited for drones and remote control vehicles, especially if the model you are building is going to fly. There are adaptive infills already implemented, which are designed to save weight while retaining strength. They do this by spacing out infill differently as it approaches the load balancing surface. Note that the first layer speed setting is consistent with the actual printing speed, set to 100% of the actual printing speed, turn off the first layer and small area printing speed reduction function, the first layer extrusion rate is consistent with the actual foaming extrusion rate, such as 270 degrees set to 45% of the first layer extrusion rate; if the bed adhesion is too strong, you can set the bottom valve when printing.Following the success of our in-house produced PolyAir 1.0 focused on improving the toughness of single-wall printed RC models, we’re presenting the PolyLight 1.0– The active foaming lightweight LW-PLA material. Depending on hotend temperature, the material increases its volume more than twice during extrusion resulting in very lightweight parts. Suitable especially for smaller models and parts where strength is not so critical. Film covered anything could potentially be lighter and ‘better’ if the wing you are trying to create suits the method well, but getting that super sleek smooth surface finish just doesn’t ever happen, the ribs always seem to tell at least a bit. It is also heaps and heaps of manual work in assembly and more design of the internal wing structures to get the finished profile you want with the required stiffness… LW-PLA is the first filament of its kind using an active foaming technology to achieve lightweight, low density PLA parts. Lower glass transition temperature, but with lower volumetric density, less prone to warping on a Sun
Not that any of wing constructions like to crash in such a fashion, RC aircraft that survive such things tend to do so not because of how the wing was made but that they are too slow flying and light there isn’t enough inertia to do anything but bounce… I don’t think it’s necessary to have the slicer do the FEA. That is the job of the design program you are using. Control extruded volume of material by regulating printing temperature. At around 230C LW-PLA starts foaming and can increase its volume by nearly 3 times. The filament is produced from premium ingredients, with tight tolerances on our automated production line and comes in a resealable bag for convenient use. Spools are made from recycled plastic waste. Assuming nozzle size and layerheight are fixed, our main input variables are Temperature, speed and flow to determine the amount of expansion. How to determine the expansion of the filamentPLA requires a lower temperature than ABS for printing. The melting point of PLA is 180 degrees Celsius, while ABS plastic melts between 200 and 260 degrees. The benefit of the lower melting point is that you do not need a heated printing bed or a closed chamber. Another advantage PLA has over ABS plastic is that it is able to print corners that are sharper. It is also easy to work with. After printing, it doesn’t require much work: at most, light sanding and rub with acetone to create smooth surfaces. Nozzle diameter – 0.4mm Step 1. Print cubes at a set speed in temperatures varying from 200°C up to 280°C We need challenging materials, we need to work with or find ways around the limitations and allow more people to experiment with exciting developments like this foaming PLA.” – Richard Horne, aka RichRap3D
Nejdůležitější vstupní proměnné pro řízení expanze jsou rychlost, teplota a průtok. To umožňuje uživatelům měnit hustotu materiálu pro různé části modelu. There are various ways of gluing pieces of PLA together, such as by using superglue, epoxy, hot glue guns, 3D pens and acetone. Each of these different bonding agents have a different method of use, and has its own set of pros and cons. In this article, we will hone in on three and include a description of what we think is the best product that is currently on the market for each respective glue. But first, here is a guide to help you to know what to take into account when you choose the type of glue that will best suit your 3D printing needs. Colorfabbs Light weight PLA (LW-PLA) is the best filament for printing RC Planes, Cosplay and other lightweight items. Parts are feather-light, yet retain good strength and are easy to cut, trim and sand. If part weight matters to you, then this is your filament of choice. Yellowing of printed parts after high temperature foaming is a normal phenomenon. Lowering the printing temperature can relieve it. Since the filament foams up when being printed, a single spool lasts for more than twice the amount of parts in volume, compared to non-foaming filaments. Lowered wing loading results in lower stall speed and impact energy when things go sideways. That means the model is less prone to damage and it actually saves costs. Suitable for paintingDifferent types of glue offer different degrees of flexibility. Some (like superglue) are more rigid, while others allow some leeway for manoeuvring of the different parts of your 3D object. Consider the purpose and desired appearance of your final product when you think about flexibility.
This is a household glue that is commonly used for an exceptionally wide variety of applications. It is hands-down one of the most popular in the world of 3D printing. Why? It’s fast-drying, cheap, easy to use and doesn’t leave much of a seam. Some glues become hot when they are curing. PLA plastics are sensitive to heat, and might start to change form, soften or melt at certain temperatures that are generated during the curing process. Glues can also react to different substances resulting in marks that form on your project, or vene result in burning through the plastic itself. Usually, the calculated flow value is lower than you would actually use for a sufficiently strong part. You might need to increase the flow rate by 5-10%. For RC planes we found 230C - 0.2mm layer height - 50/60% flow to result in sufficiently strong prints on our Prusa MK3sThese steps might seem simple, but it took about 3 weeks of experimentation to find a process that works. It’s primarily intended for straight wings with a continuous profile, but it should be adaptable to tapered/swept wings too. A well-designed airframe is essential when pushing aircraft to the edge of efficiency, like solar-powered plane to fly overnight. The next best PLA adhesive is epoxy resin. It is an extremely versatile bonding agent that is used in a variety of contexts (3D printing being one of them). We recommend this as the next best thing after super glue because, like superglue, the bond that epoxy creates is exceptionally strong. If your surfaces are not flush (i.e. the surfaces are not completely flat, resulting in small gaps), these gaps can be filled by the epoxy. G-code files are provided for you to start with both 0.3mm and 0.4mm nozzle. If you have 0.4mm Nozzle, you may want to try G-code files for 0.3mm nozzle and see if the Nozzle still can print with acceptable quality. You may notice that the result will have 20% – 30% less weight with regular PLA or PLA+. LW-PLA filament can be printed with both 0.3mm and/or 0.4mm nozzle.
