  1. I bought an Anycubic Photon via Amazon.co.uk. It looks a really well designed piece of kit. Unboxing and setting up is easy and away it went with the first print, as provided by the comapny on their usb stick. Unfortunately it didn’t complete as half the lcd screen (which masks the UV light source) went on the blink. The print quality was superb. Amazon have a fantastic return policy, collected from the door and ten minutes later notification of my refund. So impressed, thinking maybe an odd dud was to be expected, I ordered another. Similar story, tried three prints and each had a defect caused by problems with the LCD screen. Gutted, I also returned the second machine. I note that currently (May 2018) Amazon no longer stock this printer and there does not seem to be an obvious UK source. My question to those who have one... have they proved reliable in use? I have three FDM printers, but the Anycubic Photon can produce prints of tiny objects which FDM can’t do. I would risk trying another if Amazon stock them again, but a faulty one from EU or China might be difficult to return. An alternative may be the Wanhao Duplicator 7plus. Anyone experience of these?

  2. I have used Mylar successfully on my 35W HPC CO2 laser for fine detail. Bought from supplier who sells it for airbrush stencils. Varying thicknesses. For the finest detail, and to help stop it melting into a rounded edge, try cutting on low power and doing several (2 or 3) passes. Not home at present but will try to post a photo of example next week. Bob PS. I have just done a search on Amazon.co.uk for ‘mylar sheet’ and there are loads of options to buy, both thickness and quantity.
  3. I have successfully used E.M.A. Plastic Weld on PLA from Rigid Ink. This melts and 'welds' the parts together just like it does on styrene. Interestingly some PLAs respond better to it than others. A 5-minute 2-part Epoxy also works well.
  4. I use Sketchup Make 2017 on a fast computer with 256Gb solid state drive and it can take up to a minute to resize complex drawings. You get the message (not responding) top left. Just leave it for a while. Resizing in Sketchup is easy, simply draw a line of 100units with the pencil tool, switch to the tape measure tool and measure the line - you get 100 in the dimensions box. Now simply type the size required before touching any other keys (eg. 50 for half size, 200 for double the size) and press Return. Answer yes to the 're-size all model' question and your drawing re-sizes. Do this with a group or component open and you can re-size just that item.
  5. I use Sketchup and always load my exported .stl files into Netfabb and use the 'repair' option prior to printing. This resolves any problems in the mesh and makes for much more reliable 3D prints. Netfabb Basic used to be free, but it looks like all versions now cost. However, I came across this blog statement from Netfabb and hope it is of use to others........ We care about desktop 3D printing and the vibrant community of engineers, designers and makers who use our software to realize their designs. When Autodesk acquired netfabb in 2015, we knew how important netfabb Basic was to its many users. When we released the latest update of Netfabb 2017, we changed the way you can get the basic version of Netfabb. We unfortunately did not include that detail in our original announcement, and we’d like to use this post to update our users and clarify some points. Instead of downloading netfabb Basic as a separate product, all customers have to do now is download the free Netfabb trial. For the first 30 days, users will have access to all the features of Netfabb Premium, including advanced packing, support structures and support for metal additive systems. When the trial expires, the software will continue to run with the same functionality that was previously netfabb Basic. For most users, it’s still the same basic Netfabb you know and love and can be used to preview, fix, and analyze STLs and much more. Unfortunately, we do not currently offer support for Mac or Linux users. We made this change for many reasons. By accessing the basic version of Netfabb through the free trial, users get access to: The advanced features available in Netfabb Premium, making it easy to see if they're right for your business or project A free product that is updated and improved right alongside the core, professional products New capabilities like unified materials definitions and machine support After the trial, if you choose not to renew your subscription, you still maintain access to all files and have basic printing and prep functionality. The paid features like metal supports will no longer be available, but users will still be able to open saved projects, slice them, and print them. The team is committed to maintaining a free version of Netfabb as a high-quality tool for 3D viewing, repair, selective printing, and more. We will continue to update our customers on any changes, updates and new features here on the Netfabb blog.
  6. HPC will sell you a machine with support. Visit them to collect it and they will give you the training needed to look after it. My small hobby HPC 3020 I have owned for over three years and it has performed really well. I am not connected to HPC other than as a happy customer. Bob Gledhill
