METAL DLMS 3D PRINTER HANDBOOK

MetalONE is a DMLS (Direct Metal Laser Sintering) 3D printer specially designed to bring companies and trie world of research and education closer to metal 3D printing witri a limited budget. DMLS is one of trie most advanced tecrinologies triat will revolutionize trie mecrianical sector in trie future. Another peculiarity of metalONE is triat thanks to a smart design, it rias been possible to control trie costs and therefore to realize a 'democratic1 project accessible not only to large companies but also to company and educational world with low budgets. Not only trie printer cost is accessible...

We consider our metalONE a development platform as we have complete control on both hardware and software, so we are open to discuss special solutions to fulfill the needs of our users. The typical set of accessories for a metal 3D printer is: Powder sieve Vacuum cleaner Die grinder Sand blaster If a heat treatment is required to achieve the right proprieties a furnace is required. Note: accessories can be very different depending on powders or alloy you are using. All the basic required software is included with the machine. You can slice your own .stl objects and start printing the just after...

The design of parts for metal printing is different from other additive technologies so some design guidelines needs to be followed. One of the main problems is the creation of the supports as for this technology they have different functions: 1- keep the molten material in place 2- anchor the object to the construction plate 3- dissipate the heat generated by the process We had good results using Fusion 360 using the functions dedicated to generate support for laser metal printing and exporting the resulting supported structures as a single stl file. Other programs like Netfabb, Magix and Materialize...

Tensile value, elongation, modulus of elasticity and hardness properties comparable to forged or cast properties. MetalONE resources Sharebot following his philosophy of sharing experiences and solutions has created an area on his own website where users and interested people can share what has been achieved and discovered. Here is the link for the metalONE CLUB https://www.sharebot.it/en/sharebot-metalone-club/ Youtube channel Sharebot makes available on its youtube channel a series of time lapse and videos of the objects build. Linkedln metalONE club https://bit.ly/3SV0S7r

Furthermore, through an intuitive interface, it is possible to insert and/or modify all the parameters of the printing process. In the main menu you can see the build area trough a webcam and all the relevant build information. TURN OFF AFTER PRINTING MAIN PRINT SETUP SYSTEM MetalONE records in a file every data recorded during the build and these data are downloadable. In particular the internal camera archives an image just after the powder is spread (before the passage of the laser) and one after the passage of the laser. Plus you can download all the sensor's relevant data in csv (comma separated...

The typical metalONE user whats to: - study new materials and alloys, starting with little quantities to verify his characteristics and proprieties before approaching an industrial machine - personalize a DMLS machine with different sensors or process implementation - teach how 3D metal printing affects the design of pieces - allow students to experiment with a machine that's affordable and easy to use - prototype or build small pieces - a research team, universities or powder manufacturers who study new materials or new alloys.

APPLICATIONS IN ADDITIVE MANUFACTURING Oral Abstracts Concurrent Conference Session 2 | Great Room 2 Selective Laser Melting of high purity copper on a low cost, low power (250W) machine Presenting Author Gordon, Tim The University of Auckland [email protected] Diegel, Olaf The University of Auckland [email protected] Schutte, Juan The University of Auckland [email protected] This work explores the feasibility of selective laser melting (SLM) of high purity copper on a low power, low cost SLM printer, namely, the Sharebot MetalOne. Due to the high reflectivity and high...

This work is done under: Dear supporter, We are thrilled to inform you that our R&D team modified a metalONE and we are now testing almost pure copper. We began increasing the laser source power to 1 KW and changed all the optical systems accordingly. We have now entered the testing phase to find the right combination of printing parameters (laser power, speed and focus). We know that there’s a long road ahead, but we're sure that the work we're doing will bring continuous improvements to the metalONE system. The following images show the results obtained from the first print jobs with this material....
