Competitive Selling: ProX 500 vs P 396 & Fortus 900mc January 2014 www.printin3d.com | NYSE: DDD

3D Systems vs. EOS 3D Systems ProX 500 EOS P 396 $400,000 -$450,000 USD $300,000-$400,000 USD

ProX 500 vs P 396 Process Superior part surface finish and part properties Patented and exclusive roller system Wider layer thickness range 0.08 to 0.3 mm 0.003 to 0.012 in Heated feed powder and real-time temperature calibration provides superior, more consistent part properties minimizes pressure on part bed which means it does not push the already sintered parts around resulting in smoother surfaces Heated feed powder creates less shock on the powder when sintering resulting in better part properties

ProX 500 vs P 396 Process EOS process limitations Coater Pushes powder and parts Pushing cause chatter on the surface Feed powder is cold Requires thicker layers User limitations to configure parameters Parts need to be built on angle to produce good surface minimizes pressure on part bed which means it does not push the already sintered parts around resulting in smoother surfaces EOS Process

ProX 500 vs P 396 Thermal/Nitrogen Consistent Heating, Material Properties, Accuracy 6-Zone Heater for superior temperature control Real-time temperature calibration Oxygen Sensor P 396 Wider ranging temperature, material property, accuracy 5 -Zone Heater No real time thermal control No Oxygen Sensor

ProX 500 vs P 396 Imaging ProX 500 Faster Scanning, faster printing 100 W CO2 Laser 12.7 M/sec scan speeds Finer Resolution 500 micron beam size Better Accuracy & Precision Dynamic Focus (Z-Coil) P 396 Slower Scanning, slower printing 70 W CO2 Laser 6 M/sec max scan speeds most customer's run at 4.5 M/sec Inferior Resolution 600 micron beam size Lower Accuracy & Precision Theta lens

3D Systems vs EOS Software Slices on the fly-fast job submission Wide range of configurable parameters, more versatile Integrated SPC Software Tools EOS Pre-Slice parts – slower process Limiting parameter changes, less versatility No SPC Software

3D Systems vs EOS: Part Costs Duraform ProX 20% refresh rate Usage Calculations 10kg used needs 2kg new ~40% lower part cost PA2200/PA2201 50% refresh rate Usage Calculations 10kg used need 5kg new Blending Powder Ratio’s are main driver in part costs, not powder prices/kg

ProX 500 vs P 396 Build Area P 396 (Blue) ProX 500 (Yellow) 380x330x460 mm ~ 13% larger X/Y Print Area P 396 (Blue) 340x340x600 build area Big parts build in Z resulting in slower builds

What Competition Says About 3DS Myth: 3D Systems has to correct temperature on every layer to stay in control Truth: Accutemp controls temperature in real time producing consistent material properties without expert users adjusting parameters to compensate for build heights and layer scan times

Other EOS Systems Formiga P 760 Smaller build area (200x250x330 mm) 30 W laser < $200,000 USD P 760 Large build area (700x380x580 mm) Two 50 W lasers Creates a seam line on parts ~$650,000 - $890,000 Contact Me if competing against P 760 3D Systems has larger sPro SLS systems. If facing larger requirements let your RCM know and we will provide technical and sales support.

Other EOS Systems P 800 Runs PEEK material > $1,000,000 USD Print area 700 x 380 x 560 mm Two 50 W lasers Creates seam line in parts $40,000 material/build Material not recyclable <$200,000
