Hi Arnoldas, With which material are you printing that statue? I would recommend ABS and before removing the print you can take a paint brush and dip it in acetone, paint the sword and other weak spots to melt the layers together. This should strengthen the print and should allow a better removal. Otherwise you could try materials like nylon or polyester (most common ones: PET, XT, PETG, Alloy 910) Especially the Taulman3d materials have very good layerbonding strength. Good luck, Marius Breuer
Negate the sword from the model for separate printing. One of my golden rules, divide and conquer.
Most Models need post print work, Clipping, Sanding and painting.
If you need joined part to be stronger you can impose one or more post holes so that you can glue in cut down filament as posts, I find the results far stronger than just surface gluing.
