The Colander Table is designed by german based designer Daniel Rohr. The table is produced in a CNC milling process that starts with a piece of aluminum for the table top that weighs 408kg (900lb). The block of aluminum is milled down to a bowl shape with 909 holes in it. The 4 legs are made from one massive round aluminum bar. The complete timeline for producing one table from the first milling to the final polishing takes around 4 weeks.
