The Great Guide to Gluing and Assembling 3D Prints
Many of the All Nation Line new products are 3D printed using plastic filament such as PLA, PETG, ABS, ASA, PC, FLEX 98A and PVB. As part of our hobby it is interesting to understand the different types of glue that should be used for the different medias (wood, plastic, diecast, etc.). There is a very good reference article on 3D printing and gluing from Prusa Research. The article and blog can be read at this link.
One such example of why it is important to understand what the products are made from and how to glue is regarding our CB&Q Caboose Kit. The roof skins in the CB&Q Caboose Kit use FLEX 98A. Although we still like Walther’s Goo for certain applications, Goo should not be used on the FLEX skins in this kit.
Glue is one consideration regarding the properties of products using 3D printing filament. Another consideration we mention in many descriptions are those products using PLA filament. PLA is not dishwasher safe and may deform in a hot automobile in the summer time as it has a relatively low glass-transition temperature between 50 and 80 °C and a melting temperature between 170 and 180 °C.
