I’m super happy with the filament and I’m really looking forward to printing an entire plane now and seeing how it comes out. Glueing the parts together worked very well too, nice solid glue joints and I imagine the foamy structure helps the glue get absorbed a bit more than standard PLA. The part printed in regular PLA weighs 17.5 g and the one in PolyLight weighs 5.65 about 70% lighter than a standard PLA part and it was stiffer than the other attempts. Now the surface of the print looked fine (except for the stringing which was easily sanded/cut off) and the layer adhesion was very good.įor the fourth attempt I turned on the infill to about 15% just plane cubic infill and that came out awesome. So for the third attempt I increased the flow rate up to 50% and while it did improve the stiffness a little bit, there was still way to much flexibility. Only thing was it was extremely flexible, like silly flexing when I pulled it off the bed. That made a huge difference and the wingtip printed out just fine with all the structures. So for the second attempt I went ahead and turned off all retraction. About half way through it started having trouble because of the retractions. The first print I did with the standard internal support didn’t come out that great. I decided to print the wing tip from the easymax, as it’s a nice quick print and it should tell me what I want to know, basically are there any issues printing with the LW PLA. It had lots of stringing (which I was expecting, I basically used my normal PLA profile and just changed the temp and flow rate) and holy cow I couldn’t believe how light it was and it still had excellent strength. So for the first ‘real’ print I went ahead and printed a benchy. During this testing I found that 40% was spot on based on the tests. I then printed various cubes at different flow rates from 90% all the way down to 30%. It turns out that for my printer (a BIQU B1) it’s at 260 which is also the upper limit on the temperature for this printers nozzle. So first things first I did the first test of printing various cubes at different temperatures to see what temperature gave me the greatest expansion. First off I love the color they picked, a light grey is easy to paint whatever color you want, and for the model I want to print (the MIG) it actually won’t need to be painted and still will look very good. #3dlabprint problems fullWhen 3dLabPrint released their new PolyLight LW PLA at the same price but a full 1kg spool I decided to give it a try. The most common LW PLA runs about $50 for a 700g roll which makes it rather expensive even though it goes further than standard PLA. If you ever need spare parts due to loss or damage, please contact me and I will work with you to provide them.I had always heard about the LW PLA filaments and how much weight you can save, but one of the things that discouraged me from trying it was the cost. If you would prefer a different color or a specific color, please contact me and I will see what I can do. Kit will be provided in gray or white filament depending on what I have in stock.
