Durability of Snapmaker 2.0 A250

Not much has been written about durability, so I thought I’d write about it in case anyone is curious.

We use Snapmaker 2.0 A250 to sell original modeling and laser processed products.

Unit 1
Operating time
Approx. 5 days x approx. 2 hours
1 month 20 days
1 year and 7 months

At least 3,800 hours

Machine no maintenance
No heater or nozzle replacement.
ABS resin 260°C-100°C PEI

This time, a bearing was damaged and an abnormal noise occurred.
Disassembled and confirmed that one of the U-groove bearings is damaged and will be replaced.
In addition, the nozzle and heater were also replaced.

We are surprised that the machine has been able to operate with no maintenance so far.

A250 Unit 2 has been running smoothly for one year.
A250 Unit 3 is doing well with laser and prototype
A250 Unit 4 is also doing well after one year

When the axes were disassembled, the grease was black on the Y and X axes, so they were adjusted and greased.

Other than that, there are no other notable defects.

Snapmaker A250 is durable and great except for CNC machining.


This is great, thank you for sharing!

There was this thing to help with longevity.

I checked with Snapmaker support.

It was reported that “white resin block (screw nut)” for the old type linear module is no longer in production and spare parts are not available for sale.

However, they seem to sell bearings.
One bearing is 3 USD
The shipping cost is 14 USD

The only way to make white resin block (screw nut) is to make it by yourself.

I agree I have 3 SN 2.0 series (1) 350 (2) 250 and a J1 for producing PLA + parts. I have over 2 years on the 350 and 1 on the 250s. Run time at least 1000hr on 350 and about 500 on the 250 each. I find the liniear motor systems very accurate and reliable, No real maintenance.

Great product all my other 3D printers did not come close the the SN 2.0
