security and health reasons. All SLA resin types are harmful to health in direct  contact. These machines are recommended for use in well ventilated environments.  Since there is a high probability of not having an internet connection in these  environments, USB connection is used. To be more competitive tender, we kindly  request from Contracting Authority change this specification as below:  4.1.8 Printer shall have ethernet port or USB for data transfer.  Q42  Item 4.2 DESKTOP 3D PRINTER  4.2.2 Build Envelope for single nozzle shall have minimum of 200 x 200 x 200  mm.  This specification is requested 8.000.000 mm$^{3 }$effecting building volume. The device  we want to offer has 8.740.000 mm$^{3 }$(230 x 190 x 200 mm) effecting building area  and it is better than requested but the dimensions given are very specific and only  one brand (VOKSEL 3D) can be suggested considering the whole technical  specification. To be more competitive tender, we kindly request from Contracting  Authority change this specification as below:  4.2.2 Effective Building volume shall be at minimum 200 x 190 x 200 mm. These devices are benchmarked according to their printing areas  in the cartesian X-Y-Z axis system or with diameter and height  as with Delta-type 3D printers. Considering our target group’s  demands, 3D printers with a printing dimensions under  20x20x20cm do not meet their needs. Volumes of devices found  on market research are greater than the specified dimensions. Based on the market research, requested technical specifications  are available in more than one eligible product. Therefore, the  specifications remain unchanged.  Q43  Item No. 4.3, page 48-49/49, “Large Volume 3D Printer”  Combination of most of the requirements specified in the Technical specification for  LOT  4,  item  4.3  represent  only  one  manufacturer  “German  RepRap”  (https://www.germanreprap.com)  company  with  specific  model  “X1000”,  specifically:  Definition: The printer shall use  Fused Filament Fabrication  method and it shall be  compatible to utilize materials such as PLA, and PET-G.  For article 4.3.3, It has been decided that the support material  specified in the specification is for support purposes and is  thrown away after production. This material type has less  significant effect on the performance of the finished product and  this requirement has been removed to meet different devices’  specifications on the market.  Please refer to Changes No:1 to the Tender Dossier, article 4.3.3.
