![]() Right, the *.3gdrem containing binary stuff at the beginning. Then you open the g3drem file in notepad++, and you open the *.gcode file in another pane: Left, the *.gcode file produced by Craftware. ![]() A previousle made dremel 3D *.g3drem file.A text editor that will let you open a file with Binary in – Notepad++.What you can do is copy and paste the other way. Unfortunately, the first part of the file is in binary, and you can’t just copy and paste it into the G-code file we just produced. In my simple little world, I tried just opening the g3drem file in a text editor, hoping to see what was different from standard g-code. Hit the save button and save the Gcode somewhere. The sliced model complete with scaffold-style supports Take note of the top right, where you can get info on length of filament and estimated time – it’s important to note this as you won’t see it again (as we’ll see below). You can view each layer with the slider at the bottom of the screen, and follow the path of the print. You’ll now see a lovely model with scaffold-style supports. Hit the slice button and slice that model. This is what that looks like: Lovely lovely scaffold style supports! You can tweak this to enable the raft, or change the angle that requires supports, but I think to start with the defaults were fine (maybe I tweaked angle to 45 degrees). Options suitable for preparing a model to build on the Dremel Idea Builderīy hitting ‘’Auto-Generate Support”. Make sure your options (1) are set as below (this makes sure the build platform is the same dimensions as the Dremel Idea Builder) – make sure 0,0 position is set to centre, not front left, and then head to supports (2). Import your model (drag and drop works for me).This is a pretty comprehensive free slicer for 3D printing. !!!WARNING – ITS ENTIRELY POSSIBLE YOU CAN EXPLODE YOUR DREMEL IDEA BUILDER – DO THE FOLLOWING AT YOUR OWN RISK!!! So, after much tinkering (a favourite pastime of mine), I came up with the following solution. Actually 3D Builder, which comes with Windows 10, is great, and can produce excellent supports and rafts, but for some unknown, infuriating reason, it sends the files to the Dremel and sets the print temperature to 215, which is too cold and the builds generally fail (The Dremel normally prints at 220). I searched for some time to find a piece of software that could create scaffold support and output a *.3gdrem file, but it was not to be. It’s worth noting that aside from forcing this style of support, MeshMixer is a pretty decent piece of software. Secondly, I found that trying to print both halves at the same time resulted in significant curling at the build front on one while the print head was working on the other, with the curling usually ending up catching on the print head and the model being knocked over. This is less than ideal – firstly, it’s an extra step that needn’t be there. For a while I got around this by slicing the model in half, creating a flat surface, and then printing both halves separately before gluing them together. Unfortunately, I’ve generally had terrible results using them, and the result is usually a model that fails, particularly for complex, organic objects like bones that have no good flat end for attaching to the build plate. Now I’m told that these supports use considerably less plastic that the traditional scaffold. Dremel support suggest using Autodesk MeshMixer, or PrintStudio to create supports, but these pieces of software create branching, tree-like supports: Example tree-like supports around a crocodile foot in Autodesk MeshMixer, the software recommended by Dremel for producing supports. This wouldn’t be too much of a problem, except that the software the printer ships with, Dremel 3D, is incapable of adding supports and rafts, features which are pretty much essential for most prints. However, annoyingly the dremel does not accept standard gcode files, instead it only reads it’s own proprietary *.3gdrem files. The Dremel Idea Builder itself is a re-branded Flashforge Dreamer. I’ve been really impressed with the quality of the prints so far, but one area that the machine does disappoint is in the software. It’s been great, and I’ve been able to print a range of animal bones for use in practicals – students can all get exact copies of the same bone and it doesn’t matter if they break them. Last year I got hold of a Dremel Idea Builder 3D printer. **update 21/2/19: Not only has Dremel moved to a waaay better slicing software (based on Cura), but the latest firmware (v1.5, 20180611) has enabled standard *.gcode support for the 3D20 model.
