Welded Constructions with the SOLIDWORKS Structure System
From the 2004 version of SOLIDWORKS onward, the welded construction function speeds up the creation of assemblies because it allows the representation of assemblies without having to create multiple individual files. But, there is more since version 2019.
The new “Structure” function allows the creation of welded constructions in a different way. It is not necessary to draw a path for each profile. For example, it is possible to create a starting profile (“Primary Element”) from:
– From 4 planes;
– Of a path element (a bit like welded construction);
– By defining a length by selecting only one point (note the absence of a sketch in the requested selection);
– By defining an intersection between a face and a plane.
So, with a few clicks, you can define a structure, including corner treatment:
You can then modify the created structure (in one function!) to change the profiles of certain elements:
Following the creation of the external shape of the frame, reinforcements or other elements must generally be attached to it. As mentioned above, creation methods using entities other than sketch segments can be used. For so-called “secondary” elements, using the selection of two existing profiles, two methods are possible:
– Supporting Plan Element” uses an existing plan to position the newly created profile.
Activating chain selection allows the automatic creation of element pairs when two entities are selected.
– Between point elements.
This method has two ways of working, using either distance or length ratio.
The first allows the definition of two distances from the starting point of the profiles:
We can see on the screenshot above that despite the two equally defined distances, the profile is at an angle. The reason for this is that the dimension is defined by the starting point of the profile, which corresponds to the starting point of the sketch, i.e. at the top of the structure for the profile on the left of the screenshot and at the bottom for the profile on the right:
Just click on the appropriate icons to reverse the directions and thus obtain a secondary profile perpendicular to the primary profiles.
Ratios (whose value must vary between 0 and 1) of length relative to each previously selected element can also be used. In this way, always taking the direction into account, it is easy to create a spacer that would be on one side at the upper third of a profile and at the lower third on the other.
As for the creation of a drawing, the operation is the same as for a welded construction.
All in all, even if you are already using welded construction, this new working method can be confusing at first, but you quickly get used to it and learn to appreciate the lightness of the creation tree it produces. Moreover, just like the welded construction, the result produced is compatible with the BeamCutXperts beam optimization tool.

3D modeling for additive manufacturing
Repair Resolution –
You might be an engineer – if, you fix broken fitness equipment with CAD and 3D printing. This case study shows just how that was done. It starts with a budget water rower exercise machine that had arm failures in the resistance paddle which spins inside the water tank. The machine had been purchased early in the year and the paddle arms failed by December.
Note that the arms of the original paddle broke off where the plastic transitions from a thinner beam profile to the larger hub. Of course, it could have been predicted by using SOLIDWORKS Flow, Plastics, or Simulation software, but that discussion will be saved for another article.
For the moment we will focus on designing and producing a 3D printed replacement paddle that is more similar to the design used in expensive health club water rower machines.
The commercial grade water rower has single mixing paddle design that extends across the diameter of the tank. There are openings between the shaft hub and the scoop ends, but the paddle has solid plastic arms at the top and bottom of the water tank. The budget rower was connected only at the bottom of the water tank leading to increasing offset dynamic loads as athlete exertion increases.
Although the original design paddle diameter of 18 inches is larger than many 3D printer print volume dimensions, it was possible to get 16 inches diagonally across the build plate. Adjusting the width of the working portion of the paddle and having the solid section on top allows the surface area displacing the water to be similar between the 3D printed design and the injection molded paddle.
By using a pattern of triangle and diamond shapes for the open section, the replacement paddle can be printed without support.Chamfers are used for edge breaks around the edges and openings for better flow characteristics while still being easy to print.
The original paddle had a pressed and brazed connection between the paddle and rower shaft, and this has been replaced with a pentagon shaped hole to allow for screw fastening to the shaft.
For strength Markforged Onyx filament is used which is a carbon and nylon blend. The wall passes are increased and gyroid infill is used along with maintaining the full paddle width through the paddle cross section.
Disassembly of the original paddle from the rower was a bit involved, requiring drilling and a gear puller to get the shaft clear to accept the printed replacement.
Some additional drilling and bolting allowed the new paddle to be installed on the rower shaft.
With a slight adjustment of water volume in the tank, the 3D printed replacement paddle provides the same resistance and workout as the when the machine was new.
Water flow is different with the replacement paddle but the workout is the same. And the repair is done in time for a new year of health resolutions.

Metal X 3D Printing: 3 Easy-to-Make Products
written by SolidXperts – USA Senior Technical Representative John Nolin
New metal 3D printing systems are available with a much lower price point and the ability to produce parts in a growing range of alloys. This is making metal 3D printing a valid option for manufacturing firms much smaller than the aerospace companies usually associated with metal printed components.
Custom Power Train
BowHead Corp produces the Reach adventure cycle that allows disabled persons to enjoy mountain bikes or similar trail systems. The custom power train components are metal 3D printed.
The printed drive and idler sprockets are lighter weight than a machined equivalent and have held up to severe off-road trail conditions. Metal printing allows for customization of sprocket spacing and OD which can be difficult to obtain with standard off-the-shelf components.
Similar parts can be easily printed for commercial conveyor roller chain systems as well. Tables representing the appropriate ASME/ANSI B29.1 standard can be found here: https://www.engineersedge.com/power_transmission/roller_chain_dimensions_13610.htm
A Better Grip
3D printed end effectors are a popular user upgrade or customization for traditional manufacturing pick & place robots. For gripping on parts with internal course threads or other hard-to-handle surfaces, a custom-fit set of gripper fingers can be easily printed in metal.
Cast No Doubt
Sometimes the anticipated annual product quantity does not readily justify the expense and inventory issues of minimum casting runs. This is an area where the option to metal 3D print a component can have significant savings. Properly designed for the 3D metal printing process, a component can combine features that might otherwise require additional fasteners and assembly work.
These are just a few samples of the components that can be quickly and easily produced with Metal-X 3D printing. The range of metal alloys available to print is growing every few months. Currently, it includes stainless steel (17-4), tool steel (H-13, A2, D2), and Inconel (625). Additional stainless steels, Copper, and Titanium are in development. The ability to quickly and inexpensively print metal components will spur further innovation in design and help to bring production local to where it is used.

The SolidXperience Group Reveals Designs to Mass Produce Custom Ventilators in Response to the COVID-19 Crisis
St. Laurent. April 3, 2020 – A journey of a thousand miles starts with just one step. For The SolidXperience Group, that step happened on March 21st, 2020 on a couch in the socially distant living room of CEO, Alex Habrich. While watching the news with his wife, Susie, both growing increasingly concerned with the spread of COVID-19, she came across an advertisement for the Code Life Ventilator Challenge. Knowing him and the abilities of the people he employs, it was the perfect opportunity. “I know you can do this – go save lives”. That was all it took!
Our directive was clear: Design a low-cost, simple, easy-to-use, and easy-to-build ventilator that could serve COVID-19 patients, as quickly as possible. The following day Alex asked for volunteers, and a diverse team was curated from three companies and various backgrounds.
“This project is a collaboration of people from both Canada and the United States, with everyone teleworking!” – Alex P. Habrich, The SolidXperience Group CEO
Within 24 hours a team was gathered, within 8 days the designs were submitted to the challenge hosts, and within a month The SolidXperience Group will be testing a fully functional prototype of the complete OXYGEN field-ready ventilator system.
“It feels like drowning is”, the most common report from the COVID-19 patients requiring breathing assistance, and with that imagery, we took inspiration from the simplicity of a scuba breathing apparatus. The SolidXperience Group officially began tackling the problem on March 23rd, ready to help save the world however they could.
The group quickly decided the best course of action would be to produce a machine that could both conventionally connect in a hospital setting and run as a stand-alone unit in developing countries or emergency overflow.
The next step was to analyze the given product specifications and start creating schematic diagrams defining the required parts and showing how those parts interact to create the desired results. With the help of the project’s panel of medical advisors, the group was able to take the initial schematic designs and modify them as a collaborative team. All online!
Then commenced several fast-paced days of editing, revision, discussion, and decision. Affordability always being a key factor. The device needed survivability, an intuitive setup and user interface, easily maintained and replaceable parts, and it needed to be kept as inexpensive to manufacture, in mass, as possible. This iterative process proceeded until March 29th at which time schematics were finalized. With the engineering in place, product design took off.
Next, packaging: getting all the required components to fit into a manageable, transportable, robust, easy-to-operate, and reliable case. Under the pressure of the CODE LIFE contest entry submission date of March 31st, this process was successfully started and completed on March 30th. Concurrently, the digital interface was coded to manage the internal valves, solenoids, and sensors necessary to provide a clear and secure on/off readout and warning alarms.
11:58 p.m. March 31st, 2020 – The SolidXperience Group successfully submitted their entry to the CODE LIFE Ventilator Challenge and walked away with a new purpose.
Inspired by how quickly and efficiently his team was able to redesign the ventilator system while physically separated and baffled by the inflated asking price for current machines, Alex decided regardless of the outcome of the contest, The SolidXperience Group would produce their more reliable and less expensive ventilators.
The fight isn’t over yet, however! In the coming weeks, several more steps need to be taken quickly to meet the hopeful deadline of May 1st for a functioning prototype. As the physical pieces of the first construction are gathered the interface code must be tested and refined, and the assembly must go through a series of tests and simulations to determine that it meets pre-set standards and can be labeled ‘medical grade’.
Both companies in The SolidXperience Group, SolidXperts, and Mecanica Solutions, eagerly look forward to stepping out into the world, continuing our thousand-mile journey, and doing what we can to help save lives all over the world.
Thank you to the following team members and professionals for their part in the success of this project!

How Does a 3D Printer Work?
By Application Specialist – Greg Bejtlich
Despite additive manufacturing being developed in the late 1980s, the term “3D printing” has been a fairly new topic in world news. Adidas is printing footwear, ICON is printing houses, and Ford is printing car parts. There are dozens of techniques for 3D printing, some for plastics and others meant for metal. The most common being FFF, or Fused Filament Fabrication. The principle of FFF requires pushing hot thermoplastic through a nozzle and onto an adhesive bed. Depending on the style of printer, the hot thermoplastic is deposited in the X and Y-axis, cools, and moves onto the next layer. Similar to our favorite childhood toy the “Etch A Sketch”, moving the print head on the X and Y-axis can create complex shapes and pathing. Repeating this process and stacking these layers can result in strong lightweight parts.
Filament
To best understand 3D printing, we’ll start with the extruded material. The material for 3D printing is called “filament” and can vary from high-impact plastics to flexible elastomers. The most common materials printed today are ABS, PLA, and Nylon. These plastics are sold in spools and range from diameters of 1.75 – 3mm. Filaments can also be supplemented with various additives such as fiberglass, ceramic, and carbon fiber. Innovators like Markforged are creating proprietary blends of thermoplastics resulting in nylon twenty-three times stronger than ABS with a 40% increase in heat deflection.
Extruder
The spools of filament are loaded into a dry box and fed into a motorized extruder. The extruder’s bearings and toothed gears ensure that the material is fed into the hot nozzle at a constant rate and does not under extrude. Most commonly the extruder is located inside of an enclosure or mounted directly on top of the print head, also called “Direct Drive”.
Print Head
The print head consists of six major components that handle the extrusion of the build material. The filament is forcibly fed from the extruder into the heat sink and heater block. The heater block is comprised of three simple components. An aluminum block, a heating element, and a temperature sensor – most commonly called a thermistor. The heating element warms both the heater block and the filament while the thermistor keeps the temperature in check. In its molten state, the filament is pushed through an interchangeable nozzle with diameters of .1mm to 1mm. The most common filament nozzle is .4mm
The image below shows two colored areas. The red area of the diagram is the heater block providing temperatures of 180-275°. The blue heat sink is cooled by fans and prevents molten filament and heat from creeping up the print head, also known as “heat creep”. The cooling fans also ensure that the molten filament leaving the nozzle rapidly cools and adheres to the previous layer.
Print Bed
The last stage in a 3D printer is the print bed. The print bed is the flat and level surface where your part is built. The first layer of filament deposited on the print bed must have excellent adhesion or else the part may dislocate. Similar to constructing a house, the foundation’s quality will impact the rest of the building. To ensure proper adhesion, many printers have implemented heated build plates, tacky surfaces, or liquid adhesives. One-time use or disposable build plates can be inefficient and costly, unlike reusable build plates which require minimal cleanup and reduced waste
The material science and precision of 3D printing are key to the success of tomorrow’s technology. The ability to generate complex geometry with a broad selection of materials unlocks endless possibilities, and the next big idea could be yours.
If you’ve enjoyed this article and have an interest in creating strong 3D prints, head over to Markforged and check out the MarkTwo and X7. Their printers have an added twist on FFF and reinforce parts with kevlar, fiberglass, and carbon fiber. Creating parts lighter and stronger than 6061 Aluminum!
