  • 1. How to make an architectural model in a Fablab
  • 2. WHAT’S A FABLABA Fab Lab (fabrication laboratory) is a small-scale workshop offering digital fabrication. It is generally equipped with an array of flexible computer controlled tools that cover several different length scales and various materials, with the aim to make "almost anything". This includes technology-enabled products generally perceived as limited to mass production. (Wikipedia.com) HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 3. FabLab in AmsterdamNeil Gershenfeld, the «father» of FabLabs Valentina Kofi and her first PCB HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB

  • 6. - Understand the machines potentiality - Develop the project toOBJECTIVES be done with theOF TODAY machines - Realize the prototype HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 7. LASER Laser cut works by directing the output of a high-power laser, by computer, at the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high- quality surface finish.HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 8. MATERIALS It’s possible to cut: ● plexiglass (max 5mm) ● WoodPlywood (max 6mm) ● cardboard ● rubber ● etc. It’s not possible to cut: ● PC ● PVC ● Glass ● Metal ● Too thick material, even if it’s foam (i.e. PS) WE WILL MAINLY USE 3MM PLYWOODHOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 9. DESIGN - Draw unit is mm - Draw a reference rectangle of 600x450 mm - Place the pieces inside a central area of 590x440 - Design joints and notches - Place small pieces (less than 15x15) in the top area - With Autocad, move the sheet in the origin (0,0) - Check that everything is at the same Z level - Delete double lines - Explode everything in simple vectors (text, blocks, etc.) - Divide vectors in four layers: cut, engrave, dotted lines, referenceHOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB

  • 18. REMOVE DOUBLE LINES If you move different pieces close one to another please check for double lines.HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 19. MOVE TO 0,0 - select everything (Ctrl + A) - move from the bottom-left corner to 0,0HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 20. CHECK Z LEVEL - check front / right / prospective views - eventually project everything on Top planeHOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 21. EXPLODE TO POLYLINES To double check try to pick and move a control pointHOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
  • 22. HOW TO EXPORT THE FILEBEFORE PLEASE DOUBLE CHECK- no hidden object- no texture, no blocks, no texts (everything converted in polylines)- no double lines- no different Z levelsEXPORT- dxf 2004 “natural”- a multiple boards file is allowed- pdf (if you have just cut lines) HOW TO MAKE AN ARCHITECTURAL MODEL IN A FABLAB
