requirement
- [For All Members] All members of Innovation Wing are welcome to use the Ultimaker 3D printer to support their hands-on works.
- [Talk to us] Before using our 3D printers, please let us know your print job and project works by filling the 3D Printing Job Registration Form. If you do not have a project supervisor, please contact our staff (Director of Innovation Wing/ technical staff/ tutor staff), we are very happy to help you.
- [Operate the 3D printer with tutors/technicians] Please operate the 3D printer with our tutors/technicians, we are very happy to help.
-
Step 1. Create object model (.STL file)
Use any object modeling software (e.g., Solidworks / Fusion 360) or download a 3D model online for printing. Prepare the object model in .stl file format.
-
Step 2. Printing pre configuration (.G-code file)
Use Ultimaker Cura software to do pre-configuration of the print job. Do slicing and obtain the estimated printing duration and estimated material for the print job. Download the g-code file into a USB drive.
-
Step 3. Talk to on-duty tutor/technician
Come to Innovation Wing and talk to any of our on-duty tutors/technicians. They will go through the printing file with members and do a final confirmation of the printing parameters (such as duration, layer thickness, dimension, ...etc)
-
Step 4. Fill in the job registration form by members
Once confirmed, members can fill the 3D printing registration form.
Note: Printing jobs without a valid registration will be stopped immediately by staff. Printed items without a valid registration will not be collected by any members.
-
Step 5. Submit the print job to the 3D printer by tutor/technician (NOT by member)
The tutor/technician will check the registration record and once the data are verified, the tutor/technician will operate the 3D printer and submit the job with the presence of the student member.
-
Step 6. Start printing and collection of printed items
Member please come to Innovation Wing to collect the printed items. Members are encouraged to come to check the printing process frequently as there is NO GUARANTEE that the print job will be successful.
Printed items that are not collected for a week will be removed by Innovation Wing staff.
- Members please come to Innovation Wing and talk to our on-duty tutors/technicians.
- Innovation Wing tutor/technician will go through the printing file with members and do a final confirmation of the printing parameters (such as duration, layer thickness, dimension, …etc)
Once confirmed, members can fill the 3D printing registration form
- Innovation Wing tutor/technician will mark the assigned timeslot for the 3D printer on calendar.
Please click the following button to access the official user manual for Ultimaker 3 printer.
All users of this machine should read the following session about safety carefully before operating the machine.
The following are recapped from the user manual of the Ultimaker S3 printer.
1. General safety information
- Ultimaker 3D printers generate high temperatures and have hot moving parts that can cause injury. Never reach inside Ultimaker 3D printers while they are in operation. Always control the printer with the touchscreen at the front of the power switch at the back. Allow the Ultimaker 3D printers to cool down for 5 minutes before reaching inside.
- Do not change or adjust any parts of the products unless the change or adjustment is authorized by the manufacturer.
- Do not store items inside Ultimaker products.
- Ultimaker products are not intended for use by persons with reduced physical and/or mental capabilities, or lack of experience and knowledge unless they are supervised or have been given instructions concerning the use of the appliance by a person responsible for their safety
- Children should be under constant supervision when using Ultimaker products.
2. Hazards
Electromagnetic compatibility (EMC)
These devices may not cause harmful interference, and these devices must accept any interference received, including interference that may cause undesired operation.
An electrostatic discharge in some metallic parts of the devices may cause the interruption of the NFC communications, affecting the initial detection of the material spool. In these cases, a device restart should solve the problem
Electrical safety
- Ultimaker products have been tested according to the IEC 60950-1 and/or IEC 62368-1. All relevant products have undergone and passed hi‐pot testing before shipment. This test guarantees the right level of insulation
against electrical shock. An earthed mains socket must be used. Be sure that the building installation has dedicated means for over-current and short-circuiting. For more information, please visit the official website for the CB-certificate. The Ultimaker 3D printers are powered by mains voltage, which is hazardous when touched. Only trained staff should remove the bottom cover. - Always unplug Ultimaker products before performing maintenance or modifications.
Mechanical safety
- Ultimaker products are compliant with the Machine Directive 2006/42/EU. The EC declaration of conformity can be found on our website. The Ultimaker 3D printers contain moving parts. No damage to the user will be expected from the drive belts. The force of the build plate may cause minor injury, so stay out of the reach of the build plate during operation.
- Always unplug the product before performing maintenance or modifications.
Risk of burns
- There is a potential risk of burns: the print heads of the Ultimaker 3D printers can reach temperatures above 200 °C, while the heated bed can reach temperatures above 100 °C. Do not touch either of these parts
with your bare hands. - Always allow the product to cool down for 30 minutes before performing maintenance or modifications.
3. Health and safety
- 3D printing thermoplastics may result in the release of ultrafine particles (UFPs) and volatile organic compounds (VOCs) depending on the thermoplastic used and settings of the 3D printer.
- Ultimaker products are designed for use with Ultimaker materials and are open for use with materials from third-party suppliers.
4. Operation
- Do not touch the contact points on the back of the print core with your fingers.
- When using a brim, be aware of the danger of cutting yourself when removing the print from the build plate. Use a deburring tool to remove the brim once the print is taken from the build plate.
- Take the build plate out of the printer to avoid damaging the build plate clamps.
- It is advised to wear protective gloves when the support structure contains sharp corners or when working with larger models.
- Do not touch the contact points on the backside of the print core with your fingers.
5. Calibration
- Make sure there is no excess material below the tip of the nozzles and the build plate is clean before the start of a print or when you want to calibrate the build plate, or you might get inaccurate results.
- Do not touch the Ultimaker during the active leveling procedure, as this could affect the calibration process.
- Do not apply force to the build plate while fine-tuning with the calibration card, as this will lead to leveling inaccuracies.
This operational guideline is a walkthrough of the general printing procedure in Innovation Wing. You will act as a member and go through this process once.
- Step 1. Create an object model (.STL file)
- Step 2. Printing pre-configuration (.G-code file)
- Step 3. Talk to on-duty tutor/technician staff.
- Step 4. Fill in the job registration form by members, mark on the usage calendar by staff
- Step 5. Start printing and collection of printed items.
Step 1. Create an object model (.STL file)
- Members can do this part on their own computer/ in the digital learning studio.
- This is not a tutorial of Solidworks.
- 1.13. After clicking the fillet button, you can specify the items to Fillet.
- The items to Fillet are the 4 edges of the rectangle.
- Use mouse to carefully highlight the 4 edges. Note that we should select the short lines as marked by red circles in the figure.
- Once the 4 edges are selected, click the green tick to apply the fillet feature.
Step 2. Printing pre-configuration (.G-code file)
- Members can do this part in their own computer/ in the digital learning studio.
- 2.1. Open the Cura software application. The Cura software is installed in all computers in the digital learning studio and the computers next to the 3D printers. The version we used in this tutorial is 4.8.0.If you use another version, please use the following screen cap figures as a reference.
- 2.2. Load the .stl file of the 3D object.
