HIPS isn’t really good as a primary printing material. It’s OK for a limonene-removable support material, but otherwise it’s really not a substitute for ABS.
You have poor inter-layer cohesion due to too low hotend temperature.
BTW @ThantiK , HIPS and ABS are not that dissimilar. Both are graft co-polymers with styrene and butadiene, except ABS has also acrylonitrile. HIPS has relatively high impact strength, somewhat close to ABS. And… ABS will partially dissolve in limonene, too.
