Page 17: Model And Support Materials
Objet24 User Guide Model and Model and support materials are made of chemical substances. Although Support precautions must be taken when handling these materials directly, all Materials model and support materials used by the Objet system are handled in sealed cartridges. Normally, operators of the printer should never be directly exposed to hazardous materials. In the unlikely event of a leak or spill, follow the instructions that are included with the printing‐material cartridge used. Store 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 printing material is considered a hazardous substance, requiring certain precautions when directly handling it. To prevent skin irritation, wear neoprene or nitrile gloves. If there is any chance that model and support materials might splash into the eyes, wear safety goggles. Prolonged direct contact with printing materials can cause an allergic reaction. When handling UV‐cured models that may not be completely cured on the surface, common latex gloves are adequate. To prevent respiratory irritation, ventilate areas where model and support materials are used. The ventilation system should totally replace the air at least four times per hour. Clean up 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 in accordance with any applicable regulations. Absorbed printing material may re‐expose the user when these items are worn.
Page 18: First Aid For Working With Printing Materials
Safety First Aid for Working with Printing Materials In general, try to avoid direct contact with uncured printing material. If skin or eyes come into contact with it, wash the area immediately and thoroughly with water, and follow these first‐aid instructions. The Material Safety Data Sheet (MSDS) that accompanies printing materials contains important safety information. Keep this in an accessible place where these materials are used and stored. Contact with If uncured printing material comes in contact with skin, wash the affected ...
Page 19: Waste Disposal
Objet24 User Guide Waste Disposal Fully cured printed models can be disposed of as ordinary office trash. However, special care is required when handling printer waste (uncured printing material). Printing Materials When removing the waste container from the Objet printer, wear neoprene or nitrile gloves. To prevent liquid waste from splashing into the eyes, wear safety goggles. Liquid waste from the Objet printer is classified as hazardous industrial waste. Therefore, printing‐material waste must be packaged and disposed of in a manner that prevents human contact with it and contamination of water sources. Empty model‐material and support‐material cartridges contain residue of their contents. Some leakage of this residue may occur through the broken cartridge seal. Therefore, handle and store empty cartridges with care. Do not attempt to reuse empty cartridges, and do not puncture them. Dispose of used cartridges and waste containers in accordance with local regulations. Discard contaminated clothing, shoes, empty containers, etc., in accordance with any applicable regulations. UV Lamps UV lamps used by the printer to cure printing materials contain a small amount of mercury, and are considered “Universal Waste.” Recycle or discard used lamps in accordance with applicable regulations. Broken lamps: After ventilating the area, use protective gloves and carefully remove spilled mercury with a method that prevents the generation of mercury vapor, such as a syringe, packing tape or paper. Place the broken lamp, mercury and contaminated materials in an air‐tight, non‐metallic container. Dispose of the container in accordance with applicable regulations. 2–7 DOC-34014 Rev. C...

Page 24: Source Files
Introducing the Objet24 3D Printing System Source Files Objet 3D printing systems produce three‐dimensional models designed with most 3D CAD tools and with other job‐specific 3D applications. Objet systems accept: • STL Files • SLC Files Objet systems feature the capability of producing different 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 Objet system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass‐producing items. STL files can be ASCII (text) files or binary files. The content of the ASCII 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‐...
Page 25: Printing Materials
Objet24 User Guide Printing Materials Objet printers produce models by jetting thin layers of printing materials on the build tray, until the complete model is formed. Two types of material are used in this process: • Model material—which makes up the finished model • Support material—which fills gaps and spaces in the model during printing, and is removed after printing For up-to-date information about PolyJet printing materials and their properties, go to http://www.stratasys.com/materials/polyjet. Storage Materials used for printing models with Objet printers are made of resins, which are composed of reactive monomers and oligomers. Although printing materials are supplied in sealed, UV‐proof cartridges, care must be taken when storing and handling them. Follow these guidelines to protect operators and the environment, and to ensure optimum results. • 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 PolyJet printing materials. • When not in use, keep material cartridges tightly sealed to prevent contamination, the effects of exposure to UV radiation, and accidental ...
Page 26: Safety Considerations
Introducing the Objet24 3D Printing System Safety Before being cured, resins are hazardous materials. To prevent possible Considerations health hazards, follow these precautions regarding printing materials: • Do not expose to flames, heat or sparks. • Prevent contact with skin and eyes. • Ventilate areas where they are handled. • Keep them separate from food and drink. Cured plastic parts, however, are safe. They can be handled and stored without precautions. You can find more safety information about resins in “Safety Guidelines” on page 2-4, and “First Aid for Working with Printing Materials” on page 2-6.

Page 52: Copying And Pasting Objects
Using Objet Studio Copying and If you need to duplicate objects on the build tray, you can insert the same Pasting object from its file more than once. An easier way, however, is to copy and Objects paste the object. You can copy objects from the build tray or the model tree. The objects copied remain in the Windows clipboard until you paste them onto the build tray. You can also copy objects from one tray and paste them onto another, in the same way as you copy text from one document and paste it into another one. However, Objet Studio allows only one tray to be open at a time. For each build tray you need to work with (at the same time), you must open a separate Objet Studio window, by running the application again (from the Windows Start menu). Having multiple Objet Studio windows open can be convenient when you need to manipulate or configure objects before inserting them in your production build tray.
Page 53: Selecting Objects
Objet24 User Guide Selecting To manipulate an object on the build tray or assign characteristics to it Objects (building style, for example), you must first select the object. You select an object by clicking it, either on the tray or in the model tree. Its image on the build tray changes color (to light blue, by default) and its name is highlighted in the model tree. You can select multiple objects by drawing a box around them with the mouse cursor, or by pressing the Ctrl or Shift keys while clicking additional objects. Alternatively, select or de‐select objects using the following Edit menu commands: • Select All • Invert Selection • Undo Select object Figure 5-17: Edit menu Surface Finish Models can be printed with a matte or glossy surface finish. To create a matte finish, the printer surrounds models with a thin layer of support material. To set the model finish: 1.
Page 54: Positioning Objects On The Build Tray
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 supports the automatic positioning of objects. However, you should check to make sure that the objects are orientated optimally for your needs, according to the considerations explained in “Model Orientation” on page 21. Two things that affect the positioning of objects on the build tray are orientation and placement. You can let Objet Studio determine the optimum orientation and position, or you can control them. Automatic By default, Objet Studio automatically orients objects, when placed on the Orientation build tray, for the shortest printing time. (You can later change the orientation manually.) However, you can cancel automatic orientation when placing an object on the build tray. To place an object on the build tray without automatic orientation: In the Insert dialog box, make sure Orient Automatically is not selected. Figure 5-18: Orient Automatically option disabled You can change the default setting, so that automatic orientation is not applied unless you select the Orient Automatically check box each time you place an object on the build tray.
Page 55: Automatic Placement
Objet24 User Guide Automatic After placing several objects on the build tray, you can let Objet Studio Placement arrange them before printing. This ensures that the objects are positioned properly, and that they will be printed in the shortest time and with a minimum of material. To automatically arrange objects on the build tray: On the Tray Settings ribbon, click or— From the Tools menu, select Automatic Placement The effects of automatic positioning are shown in the figures below. Figure 5-19: Tray before objects are properly arranged Figure 5-20: Tray arrangement after applying Automatic Placement For best results, arrange the tray with Automatic Placement, on the Tray Settings ribbon, even if you inserted the objects with the Orient Automatically option.
Page 56: Model Orientation
Using Objet Studio Model Orientation The orientation of models on the build tray affects how quickly and efficiently they will be produced by the 3D printer, where and how much support material is used, and whether or not model parts will have a glossy 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 largest dimension along the X‐axis. Any surfaces that come into contact with support materials become matte. Since models are built up, on the Z‐axis, in 28‐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.
Page 57: Manipulating Objects On The Build Tray
Objet24 User Guide Avoid Support-Material Rule This rule considers models that have large holes or hollows, open on at least one side (like a pipe or a container). It may be advantageous to print a model standing up, so support material does not fill the hollow, even though printing the model lying down would be much faster. Manipulating Objects on the Build Tray Positioning When you use the automatic positioning option to arrange objects on the Objects on the build tray (see “Automatic Orientation” on page 18), the objects are Z-Axis positioned directly on the tray. If you do not insert objects with automatic positioning, they often appear either above or below the tray. In practice, the Objet system prints all models on the build tray on a one- millimeter bed of support material.
Page 58: Valid Object Placement
Using Objet Studio Valid Object You can ensure that models do not overlap when you position them on the Placement build tray, and that they do not extend beyond the tray. To ensure valid object placement: 1. From the Tools menu, select Constraints Settings Figure 5-22: Constraints Settings dialog box 2. Select to identify— Dynamic check • invalid object placement while placing objects—On Drop selected. • invalid object placement after moving objects—While Drag selected. • objects placed beyond the tray’s boundaries—Outside Tray selected. • objects that overlap—Object Collision selected.

There are a few differences between Objet Studio on client workstations and on the computer connected directly to the 3D printer—the server workstation. • Objet Studio installed on a client computer only displays the queue and status for jobs sent to the 3D printer server from that computer, and it allows the user to edit only these jobs. Note: If there are several Objet printers on the local network, client computers can connect to any of them, but only one at a time.
Page 94 Using Objet Studio Jobs Queue On the server, the Jobs Queue lists the last 15 jobs sent from client computers. On client workstations, the Jobs Queue lists jobs sent from that computer to the printer server. Information for each of the queued jobs is displayed, including the job status. Status Meaning Waiting Printing of this job has not started. Building Printing of this job is in progress. Stopped Printing of this job was interrupted. Printing can later be continued (Resume) or begun again (Restart). Error Errors occurred during the printing of this job, and it was placed in the Jobs Queue again.

If the application does not open and a HASP message appears, contact your dealer or Stratasys Customer Support. The Objet printer interface screen opens (see figure 6‐3). All monitoring and controlling of the printer is done from this interface.
Page 110: Loading Model And Support Cartridges
Operating & Maintaining the Objet24 3D Printer Loading Model and Support Cartridges Objet24 printers use two cartridges of Model material and two cartridges of Support material, each weighing one kilogram when full. A graphical representation of the cartridges loaded and their current weight appears in the printer interface (see figure 6‐3). Note: The printer-control interface displays the type and weight of the material cartridges loaded only if the materials drawer is closed. The printer uses RFID technology to automatically identify cartridges of printing material.
Page 111 Objet24 User Guide Tips about loading and replacing material cartridges: It recommended that you always have two material cartridges loaded in the printer. When the weight of the material in one cartridge drops below 100 grams, the printer pumps material from both cartridges until one is empty.
Page 112: Producing Models
Operating & Maintaining the Objet24 3D Printer Producing Models The Objet24 printer produces models by printing tray files prepared in the Objet Studio application and sent to the printer from there. For information about preparing model files for printing, see “Using Objet Studio” in this user guide or Objet Studio Help. The Objet24 printer is capable of printing models with the following maximum dimensions: With glossy finish— X‐axis: 234.00 mm (9.21 inches) Y‐axis: 192.00 mm (7.55 inches) Z‐axis: 148.60 mm (5.85 inches) With matte finish— X‐axis: 233.00 mm (9.17 inches) Y‐axis: 191.00 mm (7.52 inches) Z‐axis: 148.30 mm (5.83 inches) Preparing the Printer Before beginning to produce models, it is recommended that you check the current printing quality of the print heads by performing a pattern test (see “Pattern Test”...
Page 113 Objet24 User Guide In the printer interface, the printer mode changes from Idle to Pre‐print, as the printer’s components prepare themselves for production: • The print block is heated. • If more than 48 hours have passed since the last print job, the printing materials in the print heads are flushed and replaced, to ensure quality printing. (This step adds 7 to 14 minutes to the Pre‐print cycle, and it is displayed in the printer interface.) Figure 6-5: ReInitiate process during the Pre-Print cycle • The UV lamp is powered and it warms up. When printing begins, Objet Studio sends seven slices to the printer. This is the standard buffer between Objet Studio and the printer. As each slice is printed, another slice is sent 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 Objet printer.

Page 116: Resuming Production After Printing Has Stopped
Operating & Maintaining the Objet24 3D Printer Resuming Production After Printing has Stopped If the printing process is interrupted, Objet Studio stops sending slices to the printer. This can happen, for example, if the printing material runs out in the middle of a print job, and you don’t replace the empty cartridge immediately. After the printer changes to Standby or Idle mode, you need to resume printing from the Job Manager screen of Objet Studio. After printing stops, the printer goes into Standby mode, when heating of print heads is reduced. About 20 minutes later, the printer goes into Idle mode, when heating of print heads is stopped.
Page 117 Objet24 User Guide You cannot continue printing the model if: • The number of the last slice printed does not appear in the printer interface, even if the server computer displays the Continue from Slice confirmation dialog box. • There was a relatively long interruption in printing, even if the “last slice” and “continue from slice” indicators are correct. The part of the model already printed may deform or shrink, and there might be a visible difference between it and the newly printed part. The effects of a printing stoppage on a model depend on the model size and structure, Model material used, ambient temperature and the length of the stoppage. If you cannot continue printing: 1. Cancel the print job in the Job Manager screen. 2. Remove the partially printed model from the build tray. 3. Restart the job from the Job Manager screen (in Objet Studio). You can stop printing from either the printer interface or from the Job Manager screen of Objet Studio.

Page 128: Improving Print Quality
Operating & Maintaining the Objet24 3D Printer 6. Carefully inspect the test paper to see if there are missing lines. Too many missing lines, especially if they are in the same area, indicates that the quality of printing when producing models will be poor. If this is the case, see “Improving Print Quality,” below. Note: Acceptable model quality is subjective, and depends on the type and scale (size) of the models produced. As a rule, however, if two consecutive lines are missing, or if there are more than 10 lines missing in either column, the model quality is usually unacceptable.

Objet24 User Guide Testing and The effective UV radiation from the lamp used for curing models can Calibrating the change over time. Too little UV curing can cause some of the printing UV Lamp material to remain in a liquid state, on models, when printing has finished. Test the lamp and calibrate its effective UV radiation after every 300 hours of printing, or when you suspect that this is necessary, by running the UV Calibration Wizard. The wizard compares the measured radiation to the recommended radiation level. When calibrating the lamp, the wizard attempts to adjust the radiation level, if necessary. • If the reading is within the acceptable range, the wizard continues. • If further adjustment is necessary, the test is repeated. • If the UV radiation is too low to be properly adjusted, the wizard indicates that the lamp’s radiation for the printing mode is unacceptable. Before testing and calibrating the UV lamp, make sure the glass lens is clean. For easy access, run the Head Cleaning Wizard, and use the special cleaning pad supplied.

Page 174: Removing Models After Printing
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 printer, it is best to let the printed models cool in the printer, with the cover closed, as long as possible. If the 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. 3.

Objet24 User Guide Figure 7-1: 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. Soak models in a 1‐percent solution of caustic soda (sodium hydroxide) to Removing Support Material with remove support material from difficult‐to‐reach areas and to give the Caustic Soda 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.
