Manufacturing News

Since the last update, we’ve entered an intense phase in the project. Manufacturing the Lite3DP requires parts from around 30 suppliers. All of them must do their part in the agreed-upon time, which presents great challenges.

The most serious difficulty we had was when our supplier of LCD displays, whose products we had already tested and selected, simply failed us. LCD displays are one of the many components in short supply in these times and prices have risen rapidly. With considerable effort, we managed to find a new manufacturer, who sent us samples that passed our tests and could quickly manufacture the LCDs we needed. Although the cost was 74% higher than expected, we are happy to have found a reliable supplier.

Another missing component was the stepper motor we’d originally selected. Fortunately, we were able to find a substitute which upgrades the speed and accuracy of the Lite3DP. This allows the Lite3DP to move 0.000217 mm/microstep, unleashing the higher resolution of the DRV8825 driver.

With our great commitment to our backers and our desire to deliver the best product we can, we managed to add the following initially unforeseen improvements.

While we did our best to finish manufacturing by the end of May, we now expect to finish by mid-June. This means delivery of the Lite3DP may be delayed a few days, for which we are very sorry. When we get closer to the ship date, we’ll be able to inform you with greater precision.
