Safety Safety Guidelines The following general guidelines, together with the instructions provided throughout this user guide, ensure user safety while operating and maintaining the Alaris30 system. If the system is not operated as specified, the userʹs safety may be compromised. Alaris30 Installation and removal of the Alaris30 printer should only be done by Printer qualified service personnel. The Alaris30 printer should only be operated by persons trained by an Objet customer‐support representative. Service operations should be performed only by personnel who have been instructed in relevant safety precautions. All personnel operating or maintaining the Alaris30 printer should know the location of first aid and emergency equipment and how to use it. Never block access to this equipment. Never attempt to open the main cover of the printer while it is working. Never bypass the interlock safety switch. If the interlock safety switch ever fails, or if servicing is ever necessary while the main cover is open, never stare directly at the UV lamp without glasses that screen out UV radiation. For this purpose, ordinary sunglasses with UV screening are adequate. Never connect the power plug to a socket that does not have a ground (earth) wire, and never disconnect the ground. Doing so may expose the operator to serious danger from electric shock. The power cable should be connected at an easily accessible electric socket near the printer. Never insert screwdrivers, wires, or other objects into the power supply housing. Leave a minimum of 20 centimeters between ventilation openings and walls or other objects. Several parts of the printer remain extremely hot even after it has stopped operating. Avoid touching the main power supply, the UV‐ lamp power supply, UV lamp, and the print heads. Notify co‐workers and those who have access to the Alaris30 system before beginning non‐routine and hazardous work. Report any potential dangers and safety‐related accidents to your safety officer or to other appropriate authorities.
Alaris30 User Guide Model and Model and support materials are made of resins. Although precautions Support must be taken when handling resins directly, all model and support Material materials used by the Alaris30 system are handled in sealed cartridges. Normally, operators of the Alaris30 printer should never be directly exposed to dangerous materials. Most of the following recommendations for handling resins apply to the unlikely event of a leak or spill. If this should occur, follow the specific instructions printed on the printing‐ material cartridge used. Store cartridges of model and support materials indoors, in a dry area with adequate ventilation, between 16‐27 degrees Celsius (60‐81 degrees Fahrenheit). Never expose them to flames, heat, sparks, or direct sunlight. Keep model and support materials away from areas where food and drink are stored, prepared and consumed. Uncured resin is considered a hazardous material, requiring certain precautions when handling it. To prevent skin irritation, wear protective gloves, if necessary. If there is any chance that model and support materials might splash into the eyes, wear safety goggles. Prolonged direct contact with resins can cause an allergic reaction. To prevent respiratory irritation, ventilate areas where model and support materials are used. The ventilation system should totally replace the air four times per hour. Clean model‐material and support‐material spills with disposable towels or other absorbent, non‐reusable material, such as sawdust or activated charcoal. Rinse the spill area with denatured or isopropyl alcohol (IPA), followed by soap and water. Dispose of the absorbent material in accordance with local regulations. Do not wash contaminated clothing at home; clothing should be professionally laundered. Dispose of contaminated shoes, belts and other leather items. Absorbed resin may re‐expose the user when these items are worn again. 2–5 DOC-04000 Rev. A...
Safety First Aid for Working With Resins In general, try to avoid direct contact with uncured resin. If skin or eyes come into contact with resin, wash the area immediately and thoroughly with water, and follow the first‐aid instructions below. Contact with If uncured resin comes in contact with skin, wash the affected area Skin immediately and thoroughly with soap and cool water, then remove contaminated clothing. Pay particular attention to flushing the hair, ears, nose and other parts of the body that are not easily cleaned. Use cool water to prevent skin pores from opening, so that the resin does not easily penetrate the skin. Do not use solvents to clean skin. If large areas of skin have been exposed to resin, or if prolonged contact results in blisters, seek medical attention. Avoid the accidental transfer of resin from the hands to other areas of the body, especially to the eyes. If protective cream was used, do not reapply it until the skin has been completely cleansed. Contact with If uncured resin comes in contact with the eyes, flush immediately with Eyes large amounts of water for 15 minutes and seek medical attention. Avoid sunlight, fluorescent light, and other sources of ultraviolet radiation. The wearing of contact lenses when working near resin is not recommended. If resin splashes into the eyes when contact lenses are worn, immediately remove the lenses and flush the eyes with water. Clean and disinfect the contaminated lenses. Do not wear contact lenses until eye irritation disappears. Ingestion If resin is swallowed, refer to the cartridge label for specific instructions. Seek medical attention immediately.
Alaris30 User Guide Waste Disposal Fully cured resins present no special safety or health‐related issues. However, check if local regulations regard cured and partially cured resins as hazardous industrial waste, and comply with all applicable regulations governing their disposal. When removing the waste container from the Alaris30 printer, protective gloves are not required. When directly handling uncured resins, neoprene or nitrile gloves should be worn. When handling cured materials that may not be completely cured on the surface, common latex gloves are adequate. Even if not classified as hazardous industrial waste or otherwise regulated, resin materials must be packaged and disposed of in a manner that prevents human contact with the waste. Therefore, take steps to prevent the contamination of both groundwater and surface water. Empty model‐material and support‐material cartridges are sealed to prevent leakage. Do not attempt to reuse them, and do not puncture them. Discard contaminated clothing, shoes, empty containers, etc., in accordance with any applicable laws and regulations. 2–7 DOC-04000 Rev. A...

Alaris30 User Guide The Objet software arranges the jobs it receives according to their priorities, model‐material type, and other factors. In multi‐workstation configurations, the operator of the server—typically the production administrator—has total control over the jobs sent to the 3‐D printer, and can prioritize and delete jobs, review job history and reprint a job, and so Source Files Alaris30 3‐D printing systems produce three‐dimensional models designed with most 3‐D CAD tools and with other job‐specific 3‐D applications. Alaris30 systems accept: • STL files • SLC files Alaris30 systems feature the capability of producing both types of model files simultaneously. STL Files STL is short for Standard Triangulation Language. This language views any object as a collection of surfaces, and describes each surface of the object as a collection of triangles. For example, a square can be described as two triangles; a cube (six squares) as 12 triangles. Curved surfaces need more triangles to describe them. The higher the tolerance (for smooth surfaces), the more triangles are needed. The result is that high‐quality object descriptions mean very heavy files. Most CAD software can export STL files. The Alaris30 system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass‐producing items. STL files are ASCII (text) files. The content of each file begins with “solid” and ends with “end‐solid” (both lower case). Between these keywords is a list of the triangles that describes the faces of the solid model. Each triangle defines a single normal vector directed away from the solid’s surface, followed by its X‐Y‐Z coordinates. These are expressed as Cartesian coordinates and are floating‐point values. The coordinates of all triangles should be positive and should fall within the volume of the model. SLC Files SLC is short for Stereo‐Lithography Contour. SLC files describe two‐...
Introducing the Alaris30 3-D Printing System Printing Materials Materials used for printing models with Alaris30 printers are made of resins, which are composed of reactive monomers and oligomers. Care must be taken when storing and handling them, both to protect operators and the environment, and to ensure their effectiveness. Signs of premature polymerization in material cartridges may include bulging, leaking, the emission of heat, and unusual odor. Exposure to heat can cause resin to gel in the cartridge. To prevent this, observe the following guidelines when handling and storing Alaris30 modeling and support materials. Storage Printing materials used with Alaris30 systems are supplied in UV‐proof cartridges. • To ensure product stability, do not allow these materials to come into contact with metal. Plastics made from monomer‐soluble substances (such as polystyrene or polyvinyl chloride) are not suitable for storing Objet printing materials. • When not in use, keep material cartridges tightly sealed to prevent contamination, the effects of exposure to UV radiation, and accidental spillage. • Store material cartridges indoors, in a dry area with adequate ventilation, between 16–27 degrees Celsius (60–81 degrees Fahrenheit). If exposed to heat or flames, cartridges may burst or ignite. • Make sure that material cartridges are stored in accordance with all local regulations and other applicable requirements. Shelf Life Materials used for producing models have a limited shelf life. The expiry date on the label is valid when properly stored in an undamaged, ...
Alaris30 User Guide Work Environment Extreme heat and humidity conditions can adversely affect the operation of the Alaris30 3‐D printer. Therefore, it is recommended that you use ventilation or air‐conditioning systems, if necessary, to keep the work area within the following ranges: • 18°–25° C (64°–77° F) • 30%–70% relative humidity Workstation Requirements The minimum requirements for computer components used with Objet 3‐D printer software are listed in the following table.

Using Objet Studio Positioning Objects on the Build Tray To produce models efficiently and with the required finish, it is important to carefully position objects on the build tray. Objet Studio features the automatic positioning of objects. However, you should check to make sure that the objects are orientated logically for your needs, according the considerations explained in “Model Orientation” on page 10. Automatic There are two ways to have Objet Studio position the items on the build Positioning tray. • Anytime you insert an object onto the build tray, select Arrange models in the Insert dialog box.

Alaris30 User Guide Figure 5-12: Tray before objects are properly arranged Figure 5-13: Tray after objects have been automatically arranged Because of the unique characteristics of each type of modeling material, it is recommended that you select the material before inserting objects on the tray with automatic positioning or running Automatic Placement.
Using Objet Studio Model Orientation The orientation of models on the build tray affects how quickly and efficiently they will be produced by the 3‐D printer, where and how much support material is used, and whether or not model parts will have a gloss finish. Therefore, you should consider a variety of factors when deciding how to place models on the tray, using the following positioning rules. X-Y-Z Rule This rule considers a modelʹs outer dimensions. Since the print heads move back and forth along the X‐axis, the printing time along this axis is relatively short, compared to printing time along the Y‐axis and Z‐axis. From this point of view, it is advisable to place the objectʹs longest dimension along the X‐axis. Since models are built up, on the Z‐axis, in 30‐micron layers, it is very time‐consuming to print a tall object. From this point of view, it is advisable to place the objectʹs smallest dimension along the Z‐axis. Since the print heads measure about 2 inches (5 centimeters) on the Y‐ axis, models measuring less than this (on the Y‐axis) are printed in one pass. From this point of view, it is advisable to place the objectʹs intermediate dimension along the Y‐axis. Tall-Left Rule This rule considers models where, after being orientated on the build tray according to other considerations, one side is taller than the other. Since the print heads move along the X‐axis from left to right, taller sections on the right require the print heads to scan unnecessarily from the left until reaching them. If, on the other hand, the taller sections are positioned on the left of the tray, the print heads only have to scan the model until printing these sections—once the lower parts have been completed. Therefore, you should position the taller side of the model, when possible, on the left. The following rules are based on the fact that support material is not required on the top of the printed model.
In practice, the Alaris30 system prints all models on the build tray on a one- millimeter bed of support material. The importance of positioning objects directly on the build tray with Objet Studio is to correctly display the objects on the screen.
After you manually manipulate an object with the mouse, its new properties are displayed in the Transform tab of the object properties dialog box. The object properties dialog box is displayed by default (see figure 5-4 on page 4) and whenever the screen layout is changed or refreshed (see “Arranging the Objet Studio Screen” on page 6). 5–12 DOC-04000 Rev.

Using Objet Studio Valid Object To ensure that models do not overlap when you position them on the build Placement tray, you can select the Dynamic Checking icon from the Tools toolbar. When selected, Objet Studio only allows the positioning of objects if they do not interfere with other objects on the tray. Note that the space occupied by an object includes the “bounding box” surrounding it (see figure 5‐22 on page 17). Even if you do not use Dynamic Checking when placing objects on the build tray, Objet Studio automatically checks if there is a problem with the positioning of objects on the tray before sending it to the printer. You can also manually check for problems after positioning objects (see “Tray Validation” on page 22).

You can load partially used cartridges, as long as they contain more than 100 grams of material. Producing Models Before beginning to produce models, it is recommended that you clean the print heads (see “Cleaning the Print Heads” on page 13). To prepare the Alaris30 printer for producing models: 1. Make sure that the build tray in the Alaris30 printer is empty and clean. If not, remove old material with the scraper, and clean the tray thoroughly with cleaning fluid. Note: Use protective gloves when cleaning the build tray, and be careful of the sharp edges of the scraper blade.

When printing begins, Job Manager sends seven slices to the Alaris30 printer. This is the standard buffer between the Job Manager and the printer. As each slice is printed, the Job Manager sends another slice to the printer. Depending on the size of the model(s) to be produced, printing can take between several hours to several days. As long as there is enough model and support material in the supply cartridges, printing proceeds automatically until the job is finished. During printing, the server computer must remain on and it must communicate with the Alaris30 printer. Do not log-off Windows until printing is finished. The Alaris30 printer uses one model‐material cartridge and one support‐ material cartridge to produce models. When four cartridges are loaded in the printer, two of them are reserve, or standby, cartridges. By default, the printer first uses the cartridges with the least material in them. The active cartridges are blue in the printer interface. When the weight of a cartridge drops below 100 grams, the level of material in it displayed in the printer interface is red. The printer then alternates the pumping of material between the heavier and the almost‐empty cartridge. ...

Handling Printed Models Removing Models After Printing After printing models, you should allow them to cool as much as possible before handling them. If additional models do not have to be produced on the Alaris30 printer, it is best to let the printed models cool in the printer, with the cover closed, as long as possible. If the Alaris30 printer must be used to produce additional models as soon as possible: 1. Let the printed models cool on the build tray for at least 10 minutes. 2. Very carefully, remove the models from the tray with a scraper or spatula (supplied in the tool kit), taking care not to pry or bend the model. WARNING: Wear protective gloves when handling printed models before they are washed.
Alaris30 User Guide Figure 8-1: Objet WaterJet Cleaning Unit To clean a model using this device, you place it in the chamber, and you manipulate it and the jet using the built‐in, waterproof sleeves. A pump turns ordinary tap water into a high‐pressure jet, and a wiper keeps the window clear. Use caution when cleaning delicate models with high-pressure water systems. Removing Support Material with Caustic Soda Soak models in a 2‐percent solution of caustic soda (sodium hydroxide) to remove support material from difficult‐to‐reach areas and to give the model a smooth, clean finish. The amount of time you soak the model in the solution depends on how delicate it is and how much support material needs to be removed, but it is typically between half‐an‐hour and several hours. In any case, you should remove as much support material as possible before the caustic soda treatment, and rinse the model thoroughly (with a water jet) afterwards. WARNING: Caustic soda may cause chemical burns, scarring and blindness.
