Rapid-Prototyping of Rapid-Prototyping Machines
Fostering the spread of inexpensive, sustainable manufacturing processes and equipment empowers individuals and societies to create products which solve their particular challenges. We intend to advance that idea to its next logical step, offering not just the means of production, but also the mechanisms by which this empowerment can propagate and evolve. By creating rapid-prototyping machines ...
متن کاملRapid Prototyping of Rapid Prototyping Machines
Rapid prototyping tools empower individuals to create almost anything. Unfortunately, these tools are still far too expensive for personal ownership. The do-it-yourself community has responded with a slew of home-made rapid prototyping machines, but development times are slow because of the complexity of the necessary control system and the need to design the mechanical elements from scratch. T...
متن کاملEnzymatic Bleaching of Wood Pulp
The dark colour of kraft pulp after the wood chips have been heated at high temperature with NaOH solution is caused by lignin (a complex phenolic polymer) still attached to the cellulose fibres. Traditionally this pulp is treated with chlorine to bleach the pulp to make it suitable for paper making. Unfortunately this leads to the formation of some potentially toxic chlorophenolic compounds of...
متن کاملCharacterisation of water-soluble galactoglucomannans from Norway spruce wood and thermomechanical pulp
Different fractions of water-soluble polysaccharides, all composed mainly of acetyl-galactoglucomannans, from native Norway spruce wood and thermomechanical pulp were isolated and characterised. About 65% of the mannose units in the glucomannan backbone were acetylated at either the C-2 or C-3 positions in a ratio of 2.2:1.0. Mainly the mannose units, but also some glucose units, were also part...
متن کاملInfluence of hydrothermal treatment on the dimensional stability of beech wood
Hydrothermal treatment of wood material products with many interesting properties such as enhanced dimensional stability, lower equilibrium moisture content and increased biological durability. The effects of hydrothermal treatment on dimensional stability, oven dry density and water absorption of beech wood (Fagus Orientalis) naturally grown, has been studied in present research that extremely...
