Issues printing skinny alignment pegs

Recommended Posts

Hello all,

I'm trying a simple 2-part print where I align some printed holes (2.4 mm diameter) to a peg on the adjoining piece. The peg I've printed was designed to be about 2mm in diameter and around 4mm tall but seems to continuously come out as a blob that is larger than the other printed alignment hole. I've attached a picture for reference. Any clues on how to fix this?5a330d03d6736_20150423_1620441.thumb.jpg.df6dcb08c2a927229495c315d64cf081.jpg

Cory's advice is good. Alternatives are to print a small tower next to your part so the head can go over there and print that to let your pin cool down. Or you can choose "cool head lift" feature but be aware that while the head moves aside a small string will slowly come out of the nozzle and then when it goes to do the next layer it will attach that string to your pin. But these strings are easy to remove later. Still the best solution is to either print 2 at a time or add a towwer at least one layer taller than your print.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
