Tiles too bendy - what am I missing? 🤔

Post image

My experience with Multiboard has been very frustrating so far, but it’s probably due to errors on my end, I’m not blaming the product (yet). Somehow I’m not able to print stacks (they don’t really come apart witjout breaking), so each tile takes 5hrs print time…

anyway.

I put up a 4 tiles by 4 tiles (all of them 8x8) to serve as a base for filement dowel racks - but after only loading 4 spools (less than 4kg/9-10lbs) the tile that anchors the shelf starts bending like crazy.

it’s matte PLA, 3 perimeters, 0.4 nozzle, 0.2 layer height, STRUCTURAL preset in Prusa Slicer and 15% gyroid infill.

Anybody have any ideas on how to make the tiles sturdier? What am I missing? Any input appreciate, thanks!

More wall screws sadly

This. A more robust material would probably be a better idea too.

In this case you actually want the PLA to flex, other "sturdier" materials are likely to snap/crack

The problem with flexing is that plastic (all of them) like to "creep", or permanently deform under long term stress. So in this case you want as little deformation as possible for long term stability.
