Prototyping at a rapid pace
3D printed prototyping is quite simply revolutionizing product design. The ability to turn your vision into reality in a matter of hours not only accelerates the manufacturing cycle, it also means that you have more time and opportunities to perfect design before production. Get your designs experienced the way they deserve, that’s the powerful advantage of Stratasys rapid prototyping.

Design iteratively
No matter what you design, you almost never achieve a flawless product right out of the gate. Rigorous testing, evaluation and refinement are the best means to assess what works and what doesn’t. Rapid prototyping with 3D printing provides the flexibility required to make this crucial trial and error process possible for physical products.

Reduce scrap and rework
In general, the later a problem is discovered, the more costly it will be to correct. Finding and fixing problems early in the design cycle is essential to preventing scrap, rework and retooling. Rapid prototyping with 3D printing allows industrial designers and engineers more revisions in less time, so they can test thoroughly while still reducing time to market.

Communicate ideas
Physical models convey ideas to collaborators, clients and marketers in ways computer models can’t. Rapid prototyping facilitates the clear, detailed feedback essential to product success, and lets designers quickly respond to input.

Test in the real world
Know exactly how your products will look and perform before investing in tooling. A wide range of 3D printing materials can produce tough functional prototypes for highly accurate performance testing, or realistic models that look and feel like your finished products. Photopolymers, thermoplastics, metals and composite materials provide a full spectrum of material properties, many of which withstand secondary processes like sealing, polishing, painting, metallization or electroplating.

Plus, if your final production process will require molds, patterns or layups, you can 3D print short-run tooling to prove out your products and manufacturing processes before making big investments.

Air operated diaphragm pumps are designed for general use. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they could be used in potentially explosive areas.

These pumps offer the ability to vary the flow outlet and discharge pressure as slow as 0.26 gallons (1liter) per minute up to 275 gallons (1041 liter) per minute for our larger sizes and adjust fluid pressure up to 125 p.si. (8.6 bar), by using just an air filter / regulator and a needle valve.

All ARO pumps are available with convoluted diaphragms offering long product life and reduced maintenance. Metallic Materials:

• Aluminium
• Cast Iron
• Stainless Steel
• Hastelloy

Non-Metallic Materials:

• Polypropylene
• Acetal

EXP is Automation Ready

All EXP Series pumps are enhanced with electronic interface capability, providing accurate, electronically controlled dosing. Combine our pump with the ARO Controller or a PLC or PC based system and switch from inaccurate, inefficient manual processes to intelligent fluid management. Ol

When it comes to thermal processing, how do you know if you need a rotary kiln, or a rotary dryer? Though these two products share similar thermal processing principles, they are used in very different applications. While rotary kilns can dry a product, their main concern is not in drying, but simply heating.

Rotary dryers are almost always used for drawing moisture out of a material.

Typically, they operate at temperatures between 800º – 1400ºF. Rotary kilns, however, are concerned with causing a chemical reaction. Therefore, they need to operate at much higher temperatures, between 1000º – 3000º.

Rotary Kilns are designed to withstand much higher temperatures than a rotary dryer.


Typically, if you are dealing with a direct fired rotary kiln, it is refractory lined with a brick or castable lining. This lining protects the steel shell. Rotary dryers are typically not lined, and their steel is not able to withstand such high temperatures. If you are dealing with an indirect rotary kiln, the kiln is not normally lined, so the shell of the drum has to be made out of a temperature resistant alloy instead of steel.

Whether you need a rotary kiln or a rotary dryer is all dependent on what you are trying to do with your material. Are you simply looking to dry your material via thermal processing, or are you trying to cause a thermally-driven chemical reaction? The difference between a rotary dryer and a rotary kiln is simple: a rotary dryer will dry your material, and a rotary kiln will heat it up to cause a chemical reaction.
