Discovering Benefits of 3DP for Industrial Manufacturing


When the team at US-based Onulis saw a gap in the additive manufacturing space, they set out to develop a machine that would process excess and expired resin, transforming it into solid plastic stock for CNC machining, or allow for its safe disposal.

This led to a safe, sustainable cost-effective solution to handle resin in its liquid form: the WRAP machine which stands for Waste Resin Axial Printing.

The testing phase of the machine presented many challenges in that the excess resin is generally made up of different resin types all with different viscosities making it susceptible to clogging and clumping. Finding a material that was chemically resistant was a key obstacle as many materials would warp and deform when exposed to the resin. For example, ABS thermal plastic turned brittle and fragile.

Through its research, Onulis found that parts made from High Yield PA11 on the H350 did an excellent job of performing in the WRAP environment.

 

“The H350 gave us prototyping agility and through our vendor, Purple Platypus which operates 2 H350s, expedite the beta testing phase which helped us get to market quickly. The final design of the WRAP machine uses 46 plastic components printed on the H350, negating the need to invest in injection mold tooling which would have been extremely expensive, and more importantly, our time to market would have been prolonged.”

The H350 satisfied Onulis’ production demand without having to re-qualify products or processes. Thus the company was able to avoid paying for 46 injection mold tools, a huge benefit for a start-up company.

Suppes says that using the H350 meant the company could accelerate shipping globally ahead of its production schedule and avoid supply chain issues affecting the rest of the world, especially during Covid 19.

With 46 SAF parts in each machine, Onulis is able to produce 92 components in each H350 build in under 12 hours. This means over 1,288 parts can be produced per week which is enough to build nearly 30 WRAP machines per week.

The H350 3D Printer is more than just a production solution for Onulis; the properties and accuracy of the High Yield PA11 bring the characteristics needed for producing the WRAP. These include:

  • The chemical resistance of the Vat Receptacle that is repeatedly exposed to resins does not warp or break. 
  • The Door Rotating Guide is exposed to 20 pound dynamic weight which PA11 can handle due to its superior impact resistance. 
  • The Display Bezel used on the front of the machine has a smooth and attractive finish.
  • The Light Shroud Mount features a hinge which holds a replaceable component. The material has excellent elongation at break which means that will not fail.

When consistency and speed are of the essence, the H350 is capable of producing quality parts time after time that can withstand the harshest chemical environments and heavy repeated use.
