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 For the filament to expand it is necessary to put a certain amount of energy into the filament. The amount of energy a filament can absorb during printing depends on the length of the hot-zone and the time it takes for the filament to pass through the hot-zone. The longer a filament will reside inside the hot-end, the more energy it can absorb which will increase the amount of expansion. Something you should also take into account before you buy your glue, is whether or not you need to sand your surfaces before gluing them together. For some glues, having a bit of friction helps with adhesion, but this does not apply to all glue types. This is important to know when choosing the best glue for PLA.

Nozzle size is 0.30mm – 0.40mm, best with 0.30mm for PLA. No difference when printing with LW-PLA for both 0.30mm and/or 0.4mm nozzle.

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.

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.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. The exact airfoil shape of a wing has a massive effect on the performance and efficiency of an aircraft and will be selected based on the intended flight envelope. If you’re moving beyond foam board wings, 3D printing is an excellent way to create an accurate airfoil, and [Tom Stanton] provides us with an excellent guide to modeling wing sections for easy printing. We chose to make the material in light grey colour, that’s the most universal base colour for painting. Models printed in light grey are not translucent and therefore it’s easier to create a good-looking scale paint job. Parts can be easily sanded to make a nice surface finish.
