The Story Behind

My name is Mohsen and I am a PhD candidate in Robotics Engineering. About a year ago while working as a designer, I printed many prototypes on different 3D printers with price ranges from 500 to 10,000$.

Unfortunately the low cost printers were not reliable, they were slower and since the temperature of the print area was not controlled the parts lacked consistency and durability.

Even though the industrial grade one was faster, precise and reliable, it was expensive and had a small print area.

This motivated us to design Rhino, an industrial grade, all metal chassis and extruder, 3D printer with ability to control temperature of print area.

The first noticeable result of Rhino's solid chassis is that it makes it possible to print with higher speeds while maintaining accuracy. Also it is very durable.

After designing the chassis it came to design an extruder. Our goal was to build an extruder that is durable and is capable of printing wide range of materials including the ones that have high melting temperature such as polycarbonate.  We tried many different prototypes.  Unfortunately extrudes with hot-end partially made of plastic break after a while and plastic starts oozing from gaps between metal and plastic walls. Another drawback is that they can’t be heated over 250 deg Celsius. The result of designing and testing different prototypes is an all metal extruder that not only is very durable but also is capable of heating up to 300 deg Celsius. This is enough to extrude many materials, from PLA to polycarbonate

Special attention was towards the bed. We wanted something that is not only durable but also distributes heat evenly on its surface. After trying glass, plexiglass, steel and stainless still, we ended up using ¼” thick aluminum sheet. It is light and an excellent heat conductor. 

 One of the important factors while printing an object is controlling the temperature of print area. If there is too much temperature gradient in the printing area, an internal stress will build up inside the object which lowers its rigidity and makes it to bend or break. Considering this important factor, we enclosed the print area and used a closed loop controller to regulate temperature of the print volume. The result was considerably more solid printed parts.

 Even though Rhino is a durable and precise printing machine with high quality components, its consumer price could be lowered by producing a large quantity of it. At this point we have contacted major suppliers but we need your help to place an order for the raw materials needed to mass produce Rhino. 

Risks and challenges

Although Rhino Printer is designed by experienced engineers, and different prototypes were tested to ensure an optimum design, there are always unpredicted problems that may raise during mass production of a product.

Since the chassis is hand assembled and calibrated there may be imperfections that result in slower production rate. We do all our best to hire professional machinist and CNC operators to ensure all the parts are within acceptable tolerances and the production speed is remained at steady rate.

Since Rhino Printer features a heated chamber safety is our priory concern. We will perform a through quality control check to ensure every unit meets the specified standards.

To keep the production cost as low as possible electrical circuits and stepper motors are directly ordered from China and South Korea. Although overseas companies have proven to be reliable on small orders there could be delays in manufacturing and shipping large orders.
