I guess this is a Benchy, so it should be not a failure in the model.

Which printer do you have?

Tevo Tarantula 

And it fail in the model too. I printed a iron man helmet also it has the same problem .

I would first check the hardware, tighten belt, pulleys, and so on. Check if the head can mode smoothly when the steppers are disabled and you move it by hand. Maybe you need some oil on the rods, or wherever your printer need it.

 

Then check the slicing settings, print slow < 40mm/sec and check the result again. Maybe you print a way too fast and your printer cannot handle the speed.

A few weeks before it can print in 60 mm/s but what happened I don't know it can't now I tightened belts but again this result but I didn't add oil also I don't understand where I have to oil. Thank for your advice I will try them and I will reply after try them .

It is hard to give more advises, I don't know your printer, but it is definitely a hardware problem.

General it is often loose belts, bad bearings, dry axles (oil), some play in the mechanics, head not stable enough and can vibrate easily, print too fast, extrusion problem (nozzle, feeder), bad cheap filament, .......

 

So I can give you only general advices, most users here are using Ultimaker printers, so a chance to find someone who can lead you to the problem directly because he know the printer is small.
