3D printing, Rapid Prototyping and Additive Manufacturing are all terms used to broadly describe the same processes, which involve the creation of complex structures and components by the layering of materials which are gradually built up. When parts are produced the resins and contaminants must be removed or they can become permanently attached during the post curing operation. There are many different materials used for the process creating unique problems in effectively cleaning parts after processing.
Based on a long history in the parts washing industry RAMCO was selected by 3D Systems in the early 1990’s to create the first SLA cleaning systems. Since that time, and as the industry has expanded and diversified, we have developed both water based and solvent based processes and a broad line of cleaning machines to accurately and safely remove resins and contaminants without harming delicate substrates. All RAMCO systems use Dynamic Flow cleaning technology during the SLA printer cleaning process.
RAMCO, the time tested solution for Additive Manufacturing. No hype, just clean parts.
Small footprint, all pneumatic for use with alcohol and solvents. System shown with loading and unloading staging section that can be retrofit with roller conveyors as required. These same size systems are designed for water based solutions.
Larger systems like the one shown above can accommodate 60”L x 30”W x 24”H build platforms. Integrated pneumatic covers automatically open/close in sequence with the process cycle. Custom sizes are available to handle a wide variety of sizes and weights.
Multi Station Systems
RAMCO has been building semi-automated multi-station consoles for over 40 years. The above is a four stage high production system controlled thru PLC and HMI interface that can handle multiple process recipes.
This fully automated Additive Manufacturing cleaning system includes RAMCO’s patented multi-arm walking beam assembly with simultaneous transfer of all baskets. This method for transferring batch and racked loads was first introduced by RAMCO in 1989 and has been highly reliable and trouble free for over thirty years.
Before After Parts Cleaning Comparision
These parts were cleaned in aqueous solutions using RAMCO Dynamic Flow. Incorporating platform oscillation, solution turbulation ultrasonics. The parts were processed directly on either build trays or placed in baskets.
“Yazaki has owned and operated several RAMCO part washers for the last 20 years. Our Rapid Prototyping Group primarily uses them to post-process SLA (3D-printed) samples and they are part of our Additive Manufacturing business. The units have contributed to reducing the labor hours required for this cleaning process by almost 90 percent. In addition, their robustness has helped us to improve our production efficiency.”
Mark Wynn, Yazaki North America – Technical Specialist
“I have been involved in the 3D printing industry for 27 years now and have been working with RAMCO for about 25 of those 27. Dinsmore currently has 6 RAMCO units in operation for our post processing of multiple 3D printing technologies. We use them primarily for processing Stereolithography “SLA” prototype and production parts for many different applications but not limited to any one industry. Our RAMCO units play an integral part in our Additive Manufacturing process and our go to when it comes to having a quick, safe and reliable way to clean parts. We have found other clever ways to use our RAMCO units as well not just for SLA processing but for other finishing techniques for “end use” parts. The units have contributed to reducing our labor costs required for this type cleaning process and we have not found another alternative that works better to date. The RAMCO team are always there to support our operations and assist us in anyway needed to keep our projects moving forward. Our industry moves very fast what used to be a fast delivery in weeks we must now produce in only a couple of days and we need partners like RAMCO to make it possible to do what we do each and every day.”
