<p>There is a <a href="https://3dprinting.stackexchange.com/q/21186/2206">similar question</a> First layer prints just fine, then at second or third layer the printer just unsticks the small parts and makes a mess.

What's your temperature profile? Does it change after first layer?  And what about cooling profile?

There is a [similar question](https://3dprinting.stackexchange.com/q/21186/2206) First layer prints just fine, then at second or third layer the printer just unsticks the small parts and makes a mess. But the solution is "Use brim". And it sure works where brim can be used, but it can't be used in some situations.

Having your printer properly calibrated, trammed and leveled and your bed perfectly cleaned is perhaps the most important, as well as using the proper z-offset, rods lubricated, relatively stable room temperature, for example not printing in front of an open window where wind at a different outdoor temperature can blow directly on your printer.

Some other potential solutions and considerations:

1. **Bed Temperature**: Slightly increase the bed temperature for the first few layers (up to 60°C for PLA) to enhance adhesion, then reduce it to the standard temperature for the subsequent layers. This can make a significant difference in the initial adhesion of small parts.
2. **Adhesion Enhancers**: Use adhesives such as glue stick or hairspray on the bed.
3. **Print Speed and Cooling Adjustments**: Reduce the printing speed for the first few layers to allow better adhesion. Simultaneously, minimize or turn off cooling fans for these initial layers. This ensures that the material has adequate time to bond to the bed before cooling and solidifying.

These methods are focused on enhancing the initial layer's adhesion to the bed, which is critical when printing multiple small parts. You probably need to experiment with these adjustments to find the optimal balance for your specific printer, filament and environment.
