The Company sold three new and two used and refurbished 3D printers during the first nine months of 2021, compared to two new and three used and refurbished 3D printer in the prior year period.

The substantial increase in revenues from our Systems segment was due to both revenues from the sale of 3D printers and Systems-related revenues. Although the Company sold the same number of units, revenue from the sale of 3D printers significantly increased due to the product mix, as we sold more larger scale platforms in the first nine months of 2021 as opposed to smaller platforms in the comparative period in 2020. In addition, Systems-related revenues increased, which reflects the recovery from the economic slow-down mainly due to the ongoing COVID-19 situation.

There remain some constraints and obstacles, but the situation is normalizing progressively.
