![]() ![]() And there is certainly a great strength improvement over a 3d printed part without reinforcement. So extra holes and negative details that provide holding points for the cured epoxy is mandatory.Ģ- Covering a 3d printed part is much difficult than simply filling an empty part. ![]() I've listed some results from this study below.ġ-Interestingly, epoxy doesn't stick to 3d printed ABS plastic well. The parts worked great and they are still rock solid. The front bag was absolutely full with food during the whole trip and there were a lot of bumpy roads in the path too. I've used the parts during a 20 days trip around Sweden, Poland, Germany and Denmark without problems. So I started modeling my first design for the part. So I decided to use fiberglass and epoxy to do the job.įirst plan was to model the part, do the necessary modifications on the dimensions and cover all around it with fiberglass fabric and epoxy. In my previous boatbuilding experience several years ago, I saw how much some layers of fiberglass and epoxy give extra strength to a thin plywood part, enabling it to withstand strong forces easily. So I thought that it will be necessary to strengthen the part somehow. I've thought that an ordinary printed part willl not be strong enough to work properly at my bike, with heavy stuff in the bag, going on bouncy roads. Way 2 was the only choice I have, as 3d model for a specific part like this is impossible to find on the internet and I needed to modify it to fit my handlebar anyway.īut as very well known, 3d printed parts are not so famous with their strength. So you need to either find and download them from the internet or get to work and model it yourself. To produce a 3d printed part, you need to have the 3d model files for it. This is the disassembled part which I planned to produce by 3d printing. I planned to manufacture the parts with matching dimensions to my handlebar by 3d printing them. And didn't fit to mine as my bike had a 31.5mm thick handlebar. The bag's support was suitable for 1" handlebar thickness and barely fitted to my gf's bike. Recently I've bought two cycling front pannier bags. The need for me to develop this instructable arose in fact when i bought some bicycle accesories from ebay. So instead of trying to find an original replacement part for a broken one of our gadgets, robots, vehicles, mechanical toys or in any mechanical tech project we develop, we can simply go with the 3d printed parts. Strengthening a 3d part may give us the ability to use those parts in place of actual working, load bearing parts. I thought it would be great If it is possible to somehow strengthen the 3d printed parts and worked on the subject a bit. As we all know, 3D printed parts produced by our ordinary home type printers are not so strong and when used in place of actual parts, they don't last long. ![]()
