The 3D printing page always attracts a regular stream of readers so I thought I'd flag this article from HP.
Digital manufacturing with 3D printing has the potential to disrupt the $12 trillion global manufacturing sector, said Timothy Weber, HP vice president and general manager of 3D materials and advanced applications.
HP began shipping its model 4200 Multi Jet Fusion units with Voxel-level 3D printing, that has a 21-micron resolution.
A while back I mentioned a JMOL script for creating files for 3Dpriting the paper desiring the work has now been published in Journal of Cheminformatics DOI.
Three-dimensional (3D) printed crystal structures are useful for chemistry teaching and research. Current manual methods of converting crystal structures into 3D printable files are time-consuming and tedious. To overcome this limitation, we developed a programmatic method that allows for facile conversion of thousands of crystal structures directly into 3D printable files.
The Jmol 3D Print website allows the creation of STL and VRML files for 3D printing for any structure in the Open Crystallography Database. You can search either the full COD and then design your own model for printing, or search the more than 30,000 predefined sample files in the figshare collection and download the STL or WRL files that have already been created for those structures.
There is more information on the 3D printing page
Chemical Computing Group have just announced an update to MOE. This release has fixed a couple of Mac OSX 10.12 (Sierra) issues but also brings a host of new features.
- MOEsaic: Web-Application for Ligand Analytics
- Spectral Analysis for Structure Determination
- Enhanced Protein Patch Analyzer
- Integrated Antibody Project Database and Antibody Homology Modeler
- Small Footprint MOE to Facilitate Large Scale Deployments
- Physical and Virtual Rendering of Structures
A more detailed description of the new and enhanced features in MOE 2016.08 can be found at http://www.chemcomp.com/print/moe2016.08.pdf.
I’ve updated the 3D printing page to include Chemtube3D which has a number of chemical reaction transition states in both the .stl and .x3d format which work with most printers.
A list of available transition state classes is shown below:
- (C=O) Nucleophilic Substition and Addition
- Pericyclic and Diels-Alder Reactions
- Radical and Stereospecific Reactions
- Organometallic Reactions
The page I wrote on 3D printing has proved to be pretty popular so I thought I'd mention that the NIH 3D print exchange has been updated with new features to improve printability.
AstroPrint is a neat way to slice, store, and manage your print files in the cloud. The service works by taking your uploaded 3D model, adding supports, slicing it, and saving the gcode in your account online. You can then access, download, and print your models. It's like a combination of 3D printing software, such as Cura or Repetier Host, with cloud storage.
A cloud-based 3D mesh repair application from Netfabb. Sometimes the mesh of a model can contain errors that are hard to find, and even more difficult to fix. Holes, inverted normals, intersecting faces, and isolated pieces can all cause problems during 3D printing. These mistakes can occur frequently when models are generated from "messy" datasets, such as image stacks or CT data.
3D printing has become a useful way to produce representations of scientific objects of interest, whether it be small molecules binding to a target protein to complete organisms.
Traditional 3D printing uses an additive process, where successive layers of material are laid down in different shapes to slowly build up the final 3 dimensional shape. This is a time-consuming process but a new process described in Science DOI aims to reduce production times considerably, at first examination this looks to be a real game changer.
We demonstrate the continuous generation of monolithic polymeric parts up to tens of centimeters in size with feature resolution below 100 micrometers. Continuous liquid interface production is achieved with an oxygen-permeable window below the ultraviolet image projection plane, which creates a “dead zone” (persistent liquid interface) where photopolymerization is inhibited between the window and the polymerizing part.
The authors have formed a company to exploit the new technology carbon3D, the website gives more details on the technology.
The NIH 3D Print Exchange now has over 460 models available for printing, ranging from small molecules to proteins and macromolecular assemblies to anatomical models. There are also an increasing selection of lab ware, including small flasks and racks.
There are more resources details here.
There was an interesting presentation at the 248 ACS Meeting Accessing 3D Printable Structures Online Vincent F. Scalfani, Antony J. Williams, Robert M. Hanson, Jason E. Bara, Aileen Day, and Valery Tkachenko Science and Engineering Librarian, The University of Alabama email@example.com 248th ACS National Meeting San Francisco, CA August 13, 2014 slideshare describing the construction of the RSC Crystal Data Repository of crystal structures all of which can be downloaded in a format suitable for 3D printing.
Currently contains: the entire Crystallography Open Database (COD) of 289,395 .cif and 48,022 .hkl files of molecules and extended solids; 3D Printable Files – 31,239 .wrl files (color printing) and 11,732 .stl files. 3 Still in beta mode, can manually browse through files. Repository will soon have user interface that is fully searchable (name, structure, formula, SMILES, InChI, and others) with deposition and crowd-source curation/ annotation platform.
I’ve also updated the 3D printing page to include several new resources.
