Topic: Could anyone give me suggestions of how I can make this model stronger

I'm trying to 3D print this model to act as packaging for plants in delivery. The two halves of the packaging will slide over the pot and connect together, keeping the plant held firmly in place in the bottom half of the packaging, while leaving room for foliage at the top.

The problem is that I can't make a model strong enough. The base of the model that rest against the hotbed is very strong and hard for me to snap. But the arms that extend from the base are very weak and snap with little effort.

I'm using ASA filament, which is very strong and flexible. I also have polycarbonate if that would be a better choice. I'm using a Rostock Max V3 3D printer.

Up I tried putting support for the arms on the model, but that only made the arms snap where the supports ended.

Re: Could anyone give me suggestions of how I can make this model stronger

When I heard 3D modeling for the first time, it was too hard for me. So I surfed about companies that can provide me best end product. two companies that I found reasonable and good were Thomasdeandesign and Vertex modelling. But I went to Thomasdeandesign company as this was nearby and their reviews was good.

you might want to make sure your layering gives strength in the direction you need it, if the layers go across the thin part of a piece they are less strong that way, if you can turn it through 90 degrees and have the layers running the length of weaker / thinner parts, they will have more strength.

If re-orientation proves difficult/impossible, then see if PETG will meet your product's needs. It's a popular printing material for its compatibility with most machines (just a tad higher print temps than ABS, without the heated bed), in addition to low/no odor, less warping than ABS, and its balance of rigidity/flexibility. Where it really shines, though, is layer bonding: With reasonable layer heights (about 0.2mm), prints will actually have the same strength in all directions, and have less trapped air than with most other materials.
This is why transparent prints are best done in PETG: less air=less cloudiness.
