I have Pi 3b+ Can i any way connect it

Hi ,i am new to raspberry Pi ,so please help me install cura on raspberry Pi . I watched couple of tutorials and documents but i could't find any thing helpfull I even used "sudo apt-get install cura" command but it didn't work or did a thing. I tried installing linux appimage file vertion but it says invalid command. When I clicked appimage it asked me if I should execute in terminal or just execute,i tried both but it didn't react to it. I tried "chmod -x Cura3.3.4.AppImage" but it said command not found .In few they said something about ttyUSB* i didn't find it. Please help me.
