A. We suggest you use as much of the original material that is in your tank that you can and then use the 100 grams of transition material that Rapid-Cast will give you at no charge as a new customer. Allow the material to fully melt and then purge out as much as you can of this mixture. To purge the tank, remove the heated line from the jet and purge directly from the heated line. DO NOT purge through the side purge spout of the print head. When you start to get air through the heated line, you have removed enough material. Place the new Rapid-Cast material in the tank up to the normal level that you are accustomed. Allow it to melt completely. Before you connect the heated line to the jet, perform a short purge. You may have to replace the tank filter.
There are a few things that you must understand about the Rapid-Cast materials and Ballistic Fluid Technologies print heads. First, the materials have a lower processing temperature. The build material should run very well at 116 degrees C, and the support material at 108 C. The Build Heated line should be lowered to 125 degrees C when you begin. As you progress, lower the line temperature down to around 120 degrees. With the Rapid Cast materials, this should not be a problem. The Support line can be set at 110 C. Most importantly, you must eliminate the "Hot Purge" function and any other automatic temperature adjustments that raise the temperature of the lines or the print heads to 130 degrees C. Set all of the automatic temperatures to 120 degrees C. This one function, the "Hot Purge", has damaged more print heads than anything else. Another characteristic of the Rapid-Cast materials is that they solidify slower than the SS materials. As such, there is less stress and strain in the model and therefore should be less lifting and warpage than with the SS materials. To compensate for this, you must keep an eye on the cutter and check for material accumulation on the flutes of the cutter. Add more cooling time between layers until the chips on the cutter flutes get removed by the vacuum. This is true for both build and support materials. The support material is always the slowest one to solidify and therefore is the gating item for the cooling time. This situation can be significantly improved by running your machine in an air conditioned room with the room temperature at 22 C.
We offer a free 100 gram transition sample of Easy-Flow build material, Easy-Melt Premium or Easy-Melt HT to save you money. These free samples will dilute and displace previous material and aide with the changeover to our materials without stratification of model materials (although there is no danger to the machine or components while transitioning from one material to “Easy” Materials, differing materials will result in parts built with differing material layers. This may create pattern issues, as materials from other suppliers will expand or handle differently then “Easy Materials”. We thus encourage the user to change over to our materials before running parts for their clients.
Although Solidscape® requires run temperatures up to 130 degrees Celsius to accommodate their material properties, a jet should never exceed 120 degrees Celsius as the piezo epoxies can be damaged thereby shortening the life of the Print Heads. Therefor using Easy-Flow, Easy-Melt Premium and Easy-Melt HT will increase the longevity of your printheads, lines and other heated components. We strongly recommend that you start your setup by adjusting the build jet temperature to 115 Degrees C, and the support jet temperature at 105 degrees C. Also, set the calibration voltage for both to 65/25. If you require higher output to meet the Config requirements, adjust the voltage rather than the temperature. Initial adjustments should be something such as 65/20. Continue dropping the second number down as far as 65/5. If there still is inadequate output at this juncture, then begin adjusting temperature 1 degree at a time until you get to 118 degrees. Rather than going higher on the temperature, revisit the voltage setting and begin changing the voltage by modifying the 65 to 70, and so on up to 90, while leaving the 5 alone. The most important thing to remember is that "Voltage IS NOT dangerous to the print head, but Temperature CAN BE". So please, for the sake, of the print head longevity, never go above 120 degrees C. Also remember to change you.INI "Hot Purge" temperatures to 120 degrees C. This is mandatory to preserve you jet warranty involving any claim on jet damage as a result of using our materials.
Here are some steps to take while transitioning into our build and support materials:
1) WATCH THE ROOM TEMPERATURE
Your room temperatures should never exceed 21c /70f for Easy-Melt Premium and 22c/72f for Easy-Melt HT. Easy-Flow Build material can be run at these temperatures as well.
2) CONTROLLER SETTINGS
Our materials like cooler temps. Please set the controllers NO HIGHER than 110c for Easy-Melt HT an Easy-Melt Premium Support Material and 120c for Easy-Flow Build Material. If you like, experiment with even lower controller temperatures. The lower the temperature settings on your controllers, the longer your Print Heads and Lines will last. This will also mean that the material on the build plate will cool more quickly, solidifying for better cutter performance.
3) COOLING TIMES BETWEEN LAYERS
We recommend increasing the cooling times for the patterns while using Easy-Melt Support materials by a 15-25 seconds. This may add slightly to the build time (usually just a few hours). You will make up that time when post processing is quicker and easier. It will also ensure your customers patterns will not be handled as much during post processing. You'll be happy to see how "Easily" our support material "Melts" away from your patterns making clean up simple.
A. We ship all orders using USPS. Once your order has shipped, it should take 3-5 days within the United States. Global deliveries take 7-10 days.
If you requite a faster shipping method please email us at: firstname.lastname@example.org and we will try and acomidate your needs. This is usually followed by us sending you an invoice with the additional shipping costs as soon as possible. Please note that we do not ship until all of the shipping charges are paid for.
