RO stands for reverse osmosis and you can't make the membranes yourself however you can cut costs by not disposing of the "waste water" as it can still be used for flushing or laundry.

RO water is stripped of most impurites found in tap water. A quality RO membrane will remove 98%+ of the total dissolved solids (TDS) from the water.

An RO unit with a De-Ionization (DI) stage is called an RO/DI unit. The DI resin will remove what the RO membrane does not.

RO water may have a TDS of 4-10ppm (higher or lower depending on quality of membrane and TDS of source water. RO/DI water will (should) have 0ppm TDS.

A typical RO/DI unit is comprised of a pre-sediment stage, a carbon block stage, RO membrane stage, and DI stage.

While you cannot make your own unit, they are highly customizable in the sense you can add additional stages to a purchased unit, etc.
